18K is better because the purity of 18K is higher than 14K.
The purity of gold refers to the content of gold. Generally, K is used to indicate the purity of gold, the highest purity of 24K gold, 18K times, and so on. Gold's name depends on its purity.
18k gold indicates that the content of gold is 18/24, which is 75%, and the remaining 25%are other metals, which are usually copper, silver, and so on. 24K gold means pure gold.
Extension information
"AU" is a symbol used internationally to represent goldenness (that is, gold content). K gold (or opening gold) is a alloy made of gold and other metals. The characteristic of K gold jewelry is that the amount of gold is small, the cost is low, and it can be made into various colors, and it is not easy to deform and wear. K gold is divided into 24K gold, 22K gold, 18K gold, 9K gold, etc. The most common "18K gold" in my country's market, its gold content is 18 × 4.1666 = 75%, and the imprint on the accessories should be "18K" or "750". The white K gold is impure gold. It is a white alloy made of gold and gold or nickel, silver, copper, zinc and other metals. Its main component is still gold. Because white K gold is white, it is the white metal that is most likely to confuse with platinum, but it is completely different from platinum. The price of white K gold is lower than platinum and gold, and it has been widely used in jewelry production. The materials are all pure 18K gold. Including 18K platinum, 18K gold, etc. Therefore, when buying platinum (platinum) accessories, you must recognize the PT logo. 18K platinum
Colin according to national precious metal jewelry standards, only platinum can be called platinum. The market is often called platinum, which should be called 18K white K gold or 18K white gold. 18K white K gold is a mixture of 75%gold and 25%of other metals. k gold with 1. K gold jewelry of the yellow series: Golden Golden Jewelry is always the love of many women.

According to gold value, 18K gold is better. If inlay gemstones on gold, 14K gold is better. The difference between 18k gold and 14K gold . The content K as the most commonly used alloy can be calculated according to the amount of gold content. The biggest difference between 14K gold and 18K gold is how much they contain gold, according to the calculation formula of 1K = 1/24, 14K = 100%/24*14 = 58.333%(585 ‰), 18K = 4.166%*18 = 75% (750 ‰), it can be seen that the gold content of 14K gold is 58.333%, the gold content of 18K gold is 75%, the larger the number in front of K gold, and the higher its gold content. . Hardness Generally speaking, the gold content of 14K gold is lower than 18K gold, and other metal content is higher than the other metal content of 18K gold. Higher, but both can be inlaid with various gems. . Value 18k gold price will be slightly higher than the price of 14K gold, but in general, the price is moderate. It is a highly cost -effective metal in jewelry metals. When many people choose a proposal ring or a wedding ring, they will choose a 18K gold ring as a proposal ring. Like the 18K Gold DR true love ring is a good marriage proposal ring. This information 14K platinum and 18K platinum? must be 18K, and the content of 18K gold is 75%. Strictly speaking, "K platinum" is a wrong statement. Because the appearance is like platinum, the business in the market has appeared "K gold" as "K platinum", making consumers mistakenly believe that "K gold" is an impure platinum. In fact, K gold's main ingredient is gold, it is not natural white, and it is white because it adds other metals. In international standards, K gold is divided into 24 species, that is, IK to 24K. In fact, there are 17 types of K gold for jewelry. Among these 17 kinds of K gold materials, 18K and 14K are used most, and they are major jewelry raw materials in the jewelry industry in various countries. In order to enrich the expressiveness of various K gold, under the circumstances of unchanged abroad, other alloy ratio coefficients are adjusted to synthesize K gold with different colors. 14K How much is gold? k gold system is divided into 24 species, 24K gold is pure gold, and the theoretical value is 100%; correspondingly, the calculation formula of 1k = 1/24,14K gold is as follows: 14K = 100/24** 14 = 58.333%(585 ‰); is a convenient logo, and the gold content of 14K gold is generally agreed to 58.5%internationally internationally. The appearance of 4K gold is related to the characteristics of gold itself. It is explored in practice in order to meet the durability and diversity of jewelry. So the end is about 285.56 yuan/gram. 18k gold and 14K gold maintenance methods. 18k gold maintenance method. 1. When wearing a diamond ring with 18K gold inlaid, try to avoid contact with chemicals. 18k gold's primary color is golden yellow, and the white 18K gold we see is the color after electroplating. If it is often exposed to items containing chemical ingredients (such as: skin care products, hand washing solution, vinegar, etc.), the plating layer is easily corroded and exposed the primary color of 18K gold [3]. Therefore, please remove the diamond ring when applying makeup and makeup, do not wear diamond ring to cook, wash, or do chemical experiments. Before doing these things, you should gently place the diamond ring in jewelry boxes specializing in diamond ring. 2. Avoid collision or friction between hard objects such as diamond ring and metal. , although the diamond hardness is large, it may also be cracked.

Therefore, when wearing a diamond ring, it is not advisable to do severe physical or sports. In this way, it can not only wear elegant grades, but also protect the diamond ring that is not vulnerable to damage. 3. Avoid the diamond ring on an excessive cold or overheated environment The metal has the properties of thermal expansion and contraction. Therefore, the diamond ring will be affected by temperature. Putting the diamond ring in an excessive cold or overheated environment will affect the firmness of the diamond inlaid, and may even cause the diamond to loosen and fall off, causing unnecessary losses. Therefore, do not put the diamond ring in a place where it is too cold and hot, and try to avoid places with large temperature differences in hot and cold temperatures, such as cold storage and bathrooms. 4. Wipe gently with soft cloth, but do not use the hand -toilet with chemical ingredients to clean too many things to do, it is inevitable to contact many items. Therefore, the diamond ring is more vulnerable to dust. Or pollution such as oil pollution. You can wipe it gently with a soft cloth, but do not use the hand -toilet with chemical ingredients to avoid corroding valuable metals. You can also regularly go to the shops in the purchase of diamond rings to ask the staff to help clean it, remove the dust, oil and other impurities, etc. This can avoid the damage of these impurities to the diamond ring and make the diamond ring refreshed. It in other words, the maintenance of 18K gold wedding diamond ring, which is usually the precautions when wearing, as long as these matters can be noticed, that is the best maintenance of the 18K gold diamond ring. 14K gold maintenance method 14k gold is stable in normal conditions and will not be refunded or deforms, but like all valuable metals, we must also pay attention to maintenance and reasonable wear to maintain its shape and gloss. In first, try to avoid contact with some acidic and alkali chemicals. Stay away from those corrosive chemicals such as chlorine gas and cleaning agent. Secondly, pay attention to reasonable matching, reduce daily wear, bumps and other damage, and prolong the color life of gold. Third, the method of cleaning 14K gold is as follows: Use a soap temperature water solution, and use a soft brush to gently clean it, and then gently dry it with a soft cloth.

The understands of K gold's meaning and calculation method, so it is not difficult to know how many types of K gold are. According to international standards, K gold is divided into 24 species, that is, IK to 24K. However, the types of K gold for jewelry are not yet these, and the jewelry materials used in the world are not less than 8K. In this way, there are actually 17 types of K gold for jewelry. M of these 17 kinds of K gold materials, 18K and 14K are the most used, and it is the main jewelry raw materials in the jewelry industry in various countries. In order to enrich the expressiveness of various K gold, under the circumstances of unchanged abroad, other alloy ratio coefficients are adjusted to synthesize K gold with different colors.
18K. White gold, also known as K platinum and platinum, is actually a alloy. Its code WG (white GDD) means white gold. Generally, WG585 (14K) , WG750 (18K) is often used abroad or only with a digital representative content and white gold. It is not easy to lose luster. Platinum, also known as pure platinum, its symbol is PT, silver-gray white, a grade of 21.35, a melting point of 1700 ° C, Moh's hardness 4-4.5 degrees, chemical stability, except for king water, which is not corroded by acid and alkali. Pure platinum is relatively soft. Add metal such as 钯, 铑, calcium, and calcium will increase its hardness. The international platinum poke is PT, and the purity is represented by a number, such as PT900, PT950, PT990. This gold is a member of the platinum family. Under normal conditions, it is not easy to oxidize and loses luster. The temperature will produce oxides on the surface of about 400 ° C. It is PD950, indicating that the content of the pantra is 950%. In the irregular market, platinum and K platinum are used to being used to platinum, so some consumers suspect that platinum and platinum are metal? platinum, also known as platinum. Its English is Platium, which is generally coded by its abbreviation PT. The gold jewelery marked with 18K platinum or 18kWG sold by merchants is a white alloy of 25%or nickel in gold. It is actually a type of K gold, and its gold content is 75%.
is like this, so there is no need to worry. The reference to this:
What is platinum, platinum, K platinum and gold in recent years, silver -white precious metal inlaid jewelery has been popular in recent years. In malls, the names of these precious metals are often at a loss. In in Taiwan, these white metals are called in Platinum and K platinum (silver is not discussed here). In fact, this statement often causes misleading and confusion. We must explain according to the naming of the elements on the chemical cycle table to get a reasonable name.
. White Gold:
The so -called K platinum and platinum on the market are actually a alloy of gold, nickel, copper, and zinc. Or gold and silver, or alloy of gold, silver and copper. It also includes the alloy of gold and crickets often adopted by the Taiwanese masters. Its code WG (White Gold), which means white gold. In the early days, 226 (60 % of gold, 钯 20 %, and 20 % of copper) represents white gold containing 600/1000, which is commonly known as "material", which means silver white metal containing gold, instead of not gold without gold, not gold without gold, not gold without gold, not gold without gold, not gold without gold, not gold without gold. Nickle Alloy electroplating. Generally use abroad; WG585 (14K), WG750 (18K), or only the gold content with digital. The white gold has good reflexity and is not easy to lose luster. Before the use of platinum and 钯 in the future, white gold is mainly used to inlay gemstone silver white metals.
. Platinum:
, also known as pure platinum, positive platinum or real platinum. But these titles are unreasonable and easily confused with white gold. Its symbol is PT, silver gray -white, a gravity of 21.35, a melting point of 1700 ° C, and a Mohs hardness of 4 -4.5 degrees. It is chemical and stable. The pure platinum is relatively soft, and adding metals such as 钌, 铑, and 钯 will increase its hardness. South America's Indian people made platinum jewelry as early as the 15th century, and Europeans began to adopt until the middle of the 19th century. At present, Japan is the largest consumer of platinum.
three, platinum alloy (Platinum AlLoy):
alloys made of platinum mixed with other metals, such as 钯, 铑, 钇, 钌, cobalt, 锇, 锇, Copper, etc. Although platinum hardness is higher than that of gold, it is still not enough to use it as a mosaic. It must be used to make jewelry with other metal alloys. This use of platinum, cricket alloy and platinum, and crickets are used. Platinum and cobalt alloys are used in Europe and Hong Kong. Platinum (85%) in Japan manufacture chains. The poke of platinum jewelry internationally is the word PT, Plat or Platinum, and represented by a thousand points of purity. For example, PT900 means that the purity is 900%O. The specifications of Japanese platinum jewelry are marked with PT1000, PT950, PT900, and PT850.
. Palladium:
is a member of the platinum, silver -white, symbol PD, a proportion of 12, light than platinum, strong ductility, than platinum, than platinum Slightly hard, insoluble in organic acid, cold sulfuric acid or hydrochloride. But dissolved in nitric acid and Wang Shui. Under normal conditions, it is not easy to oxidize and loses gloss. The temperature will generate oxides on the surface of about 400 ° C, but the temperature will be restored when the temperature rises to 900 ° C. At present, it is cheaper than platinum. The jewelry industry is used alone, or it is composed of gold, silver, and platinum alloy. Sometimes I participate in some crickets to increase their hardness. Common gold on the market, k k 市场, platinum, and 钯 alloy. Specifications are marked with PD1000, PD950, PD900
-Platinum and platinum 1, thousands of gold refers to pure gold jewelry of 99.9 %, engraved with 999 or thousands of foot gold printing Essence 2, foot gold refers to pure gold jewelry with a gold content of 99%, with 99%or foot gold engraved. 3, 18K gold refers to jewelry containing 75 % gold ingredients, and the remaining 25 % are other precious metals, with 18K or 750 marks. 4, 18K platinum refers to gold jewelry containing 75 % golden ingredients, white gold jewelry, and the remaining 25 % of other white golds, engraved with 18K or 750 imprints. 5, PT900 refers to platinum with 90 % platinum, and the remaining 10 % are other precious metals. Platinum and cricket content reaches 950 % of platinum accessories. The mark is PT900. 6. PT950 refers to accessories containing 95 % platinum ingredients, and the remaining 5 % are other precious metals and the mark is PT950. The metal composition is completely different. On the chemical element table, one is Gold, and the other is Platinum
-how to identify Platinum and silver expensive. Platinum is gray -white and is easy to confuse silver. Consumers who buy metal to buy metal jewelry should correctly recognize platinum and silver. The identification method is: 1. See the mark. If there is "PT" or "Platnum" or "Plat" on the jewelry, it is platinum; if there is the word "S" or "Silver", it is silver. 2. Weighing method. The proportion of platinum iron is 21.4, and the proportion of silver is 10.49. Comparing the weight of the same volume, the weight of the platinum is almost double the weight of the silver. 3. appearance comparison. Platinum is gray -white and the texture is relatively hard; while silver is white, the texture is delicate and smooth, softer than platinum. 4. Fire burning method. After the high temperature was burned and cooled, the platinum color remains unchanged and still gray -white; while silver becomes moisturizing, or black and red. 5. Chemistry identification method. Moch white gold on the test goldstone and drip on the goldstone with nitric acid and hydrochloric acid. If the material exists, it is platinum; the silver is grinded on the test gold stone, drops a few drops of nitric acid, and rinse it with water. If the material disappears, it is silver.
18K is better because the purity of 18K is higher than 14K.
The purity of gold refers to the content of gold. Generally, K is used to indicate the purity of gold, the highest purity of 24K gold, 18K times, and so on. Gold's name depends on its purity.

in recent years, silver -white precious metal inlaid jewelery has been popular in recent years. In malls, the names of these precious metals are often at a loss.
In in Taiwan, these white metals are called in Platinum and K platinum (silver is not discussed here). In fact, this statement often causes misleading and confusion. We must explain according to the naming of the elements on the chemical cycle table to get a reasonable name.
. White Gold:
The so -called K platinum and platinum on the market are actually a alloy of gold, nickel, copper, and zinc. Or gold and silver, or alloy of gold, silver and copper. It also includes the alloy of gold and crickets often adopted by the Taiwanese masters. Its code WG (White Gold), which means white gold. In the early days, 226 (60 % of gold, 钯 20 %, and 20 % of copper) represents white gold containing 600/1000, which is commonly known as "material", which means silver white metal containing gold, instead of not gold without gold, not gold without gold, not gold without gold, not gold without gold, not gold without gold, not gold without gold. Nickle Alloy electroplating. Generally use abroad; WG585 (14K), WG750 (18K), or only the gold content with digital.
The white gold has good reflexity and is not easy to lose luster. Before the use of platinum and 钯 in the future, white gold is mainly used to inlay gemstone silver white metals.
. Platinum:
, also known as pure platinum, positive platinum or real platinum. But these titles are unreasonable and easily confused with white gold. Its symbol is PT, silver gray -white, a gravity of 21.35, a melting point of 1700 ° C, and a Mohs hardness of 4 -4.5 degrees. It is chemical and stable.
The pure platinum is relatively soft, and adding metals such as 钌, 铑, and 钯 will increase its hardness. South America's Indian people made platinum jewelry as early as the 15th century, and Europeans began to adopt until the middle of the 19th century. At present, Japan is the largest consumer of platinum.
three, platinum alloy (Platinum AlLoy):
alloys made of platinum mixed with other metals, such as 钯, 铑, 钇, 钌, cobalt, 锇, 锇, Copper, etc. Although platinum hardness is higher than that of gold, it is still not enough to use it as a mosaic. It must be used to make jewelry with other metal alloys.
This use of platinum, cricket alloy and platinum, and crickets are used. Platinum and cobalt alloys are used in Europe and Hong Kong. Platinum (85%) in Japan manufacture chains. The poke of platinum jewelry internationally is the word PT, Plat or Platinum, and represented by a thousand points of purity. For example, PT900 means that the purity is 900%O. The specifications of Japanese platinum jewelry are marked with PT1000, PT950, PT900, and PT850.
. Palladium:
is a member of the platinum, silver -white, symbol PD, a proportion of 12, light than platinum, strong ductility, than platinum, than platinum Slightly hard, insoluble in organic acid, cold sulfuric acid or hydrochloride. But dissolved in nitric acid and Wang Shui. Under normal conditions, it is not easy to oxidize and loses gloss. The temperature will generate oxides on the surface of about 400 ° C, but the temperature will be restored when the temperature rises to 900 ° C. At present, it is cheaper than platinum. The jewelry industry is used alone, or it is composed of gold, silver, and platinum alloy. Sometimes I participate in some crickets to increase their hardness. Common gold on the market, k k 市场, platinum, and 钯 alloy. Specifications are marked with PD1000, PD950, PD900
-Platinum and platinum
1, thousands of gold refers to pure gold jewelry of 99.9 %, engraved with 999 or thousands of foot gold printing Essence
2, foot gold refers to pure gold jewelry with a gold content of 99%, with 99%or foot gold engraved.
3, 18K gold refers to jewelry containing 75 % gold ingredients, and the remaining 25 % are other precious metals, with 18K or 750 marks.
4, 18K platinum refers to gold jewelry containing 75 % golden ingredients, white gold jewelry, and the remaining 25 % of other white golds, engraved with 18K or 750 imprints.
5, PT900 refers to platinum with 90 % platinum, and the remaining 10 % are other precious metals. Platinum and cricket content reaches 950 % of platinum accessories. The mark is PT900.
6. PT950 refers to accessories containing 95 % platinum ingredients, and the remaining 5 % are other precious metals and the mark is PT950.
The metal composition is completely different. On the chemical element table, one is Gold, and the other is Platinum
-how to identify Platinum and silver expensive. Platinum is gray -white and is easy to confuse silver. Consumers who buy metal to buy metal jewelry should correctly recognize platinum and silver. The identification method is:
1. See the mark. If there is "PT" or "Platnum" or "Plat" on the jewelry, it is platinum; if there is the word "S" or "Silver", it is silver.
2. Weighing method. The proportion of platinum iron is 21.4, and the proportion of silver is 10.49. Comparing the weight of the same volume, the weight of the platinum is almost double the weight of the silver.
3. appearance comparison. Platinum is gray -white and the texture is relatively hard; while silver is white, the texture is delicate and smooth, softer than platinum.
4. Fire burning method. After the high temperature was burned and cooled, the platinum color remains unchanged and still gray -white; while silver becomes moisturizing, or black and red.
5. Chemistry identification method. Moch white gold on the test goldstone and drip on the goldstone with nitric acid and hydrochloric acid. If the material exists, it is platinum; the silver is grinded on the test gold stone, drops a few drops of nitric acid, and rinse it with water. If the material disappears, it is silver.
