KGold is an alloy of gold and other metals. Because pure gold has low hardness and is easily deformed, it is not conducive to setting precious stones or making precise styles, and K gold is enough hardness to make up for the shortage of pure gold. The K number will vary depending on the gold content.
In China, 18k gold is widely used, while Hong Kong and Europe and the United States will choose 14k and 9k for jewelry. In the market, there are mainly three colors of k gold: white gold, yellow gold and red gold. However, the color of K gold is actually very diverse, so why do k gold have different colors? Let's come together.
White gold

White k gold mainly has two kinds of coloring metals. One is nickel, which can be mixed with gold to make it white (or gray), but because if the nickel exceeds the standard, it will cause skin irritation to the wearer, so good k platinum will be used less, and more used. It is palladium. Palladium is another metal used in the manufacture of K white gold. Because it is in the same family as platinum metal, it is more expensive than nickel, but it does not cause allergic reactions. In addition to palladium, some metals such as silver and zinc are mixed to increase the hardness.
Red gold
(Rose&PinkGold)
Red gold is also called rose gold, mainly with copper added for coloring. Different proportions of copper will give it a pink or rose red color. The more copper content, the darker the color. So we can see different factories in the market, or the color depth of different batches of red gold will usually be different.
Green K gold
(GreenishGold)
This color of K gold, will be used in the retro design of Europe and the United States. Mainly because silver is added to k gold, and sometimes a small amount of cadmium is added for color matching. Green k gold is quite rare because its green color is very subtle. Personally feel that it is not so much green, it is better to say that yellow-green or tender green is more appropriate.
Black gold
(BlackGoldAlloys)
Black k gold is also seen more and more on the market, becoming a more popular element nowadays. Black k gold is mainly mixed with iron or colored by electroplating.
Blue K gold
(BlueGoldAlloys)
The extremely rare k-gold color, a blue gold gold bar that was displayed at the 8th Dubai Gold Exchange in 2011, attracted many people's attention. Due to the fact that its k-gold formula is less disclosed, it has not been promoted in the market, but it is expected that there will be a popular opportunity in the future.
Purple K gold
(PurpleGoldAlloys)
Purple K gold is also a rare K gold, mainly added to the aluminum to make it discolored. The color of the aluminum varies, and the color depth will vary.
In fact, it is not an easy task to make K gold jewelry. Before manufacturing, craftsmen must consider adding metal interactions to make the finished product color, hardness, and durability appropriate. Perhaps the same color of K gold, the metal ratio will be a lot different.
