Gold necklace refers to a necklace made of gold as the main raw material. The chemical symbol of gold is Au, with a specific gravity of 17.4 and a Mohs hardness of 2.5. Gold ornaments can be divided into pure gold and k gold according to their gold content. The gold content of pure gold jewelry is above 99%, and the highest can reach 99.99%, so it is also called "99 gold", "all gold" and "red gold". In order to overcome the shortcomings of gold, such as high price, low hardness, single color, easy wear and delicate pattern, some other metal elements are usually added to pure gold to increase the hardness of jewelry gold, change its color tone and lower its melting point, so that gold alloy jewelry with different colors and obviously different gold contents appears, and is marked with the word "Kai". K-gold system is an internationally accepted standard of gold measurement. The complete characterization of K-gold is "K-gold", which gives K-gold an accurate gold content standard, thus forming K-gold jewelry series.

If you buy jewelry,

I have two suggestions.

1. If you watch it at home, you can find the brand online.

2. If you want to see the real thing, it is recommended to try it on directly in the regional physical store.

There are several diamond rings under the brand name, all of which are good.

For example, my Zakaly diamond bird Clankin Taifu diamond likes to drill.

Take Jin Taifu as an example.

Jintaifu is a merchant engaged in online diamond sales in Hongkong and Chinese mainland, integrating jewelry research and development, design, wholesale and sales. His home is an O2O sales model that combines "physical stores and online stores". Jintaifu Diamond pursues simplicity and fashion, and creates jewelry with oriental cultural and artistic colors, so that lovers all over the world can have unique Cupid diamond ornaments and witness their eternal love. So it will be much cheaper to buy his brand of jewelry!

These brands can be seen on Tmall ~

If you go to a physical store, you might as well find their official website address first, and then find a physical store in your area to try it on directly.

I am lazy and buy it directly on Tmall.

I'm tired of typing. I hope to adopt ~ ~
