18k Necklace

18k gold is a type of gold that is not pure and is produced by humans with a mixture of other various materials. However, it does contain more pure gold than other types of gold. 18k gold can be found in three types which can also be classified according to their color. Yellow gold is the purest gold out of rose gold and white gold. It also consists of rich and vibrant gold color which is brighter than 10k and 14k gold necklace. White gold is the most popular metal when it comes to jewelry. The silvery color of the gold has always made it a topic of discussion. As for rose gold, it is a new type of gold that doesn't seem to go out of trend anytime soon. The mixture of various metals gives this gold pinkish color.

The pure 18k gold is most well known because the gold doesn't trigger and irritate skin which leads to fewer skin infections. Various types of jewels made from 18k gold can be found.
