1, color, compared with silver, K gold is gray to the naked eye and hard in texture; Silver is clean and white to the naked eye, and its texture is fine and smooth, but its hardness is lower than that of K gold and it is easy to deform.
2. Craft: 18k gold is the first choice for complex jewelry by many jewelry designers because of its hard texture.

3, label, real 18k gold necklace will be printed with the steel seal of the product label, G 18K, 18K or 750, if there is no label necklace, it is probably fake K gold. In addition, the necklace has 18kGF or 18KGP steel seal, which is 18K alloy or cast gold, but not real 18K gold.
4. Look at after-sales service. Although the real 18k gold necklace is cheaper than the gold jewelry, it is also a gold jewelry, but the color is different, so 18K gold necklace can be sent to a jewelry store for cleaning and polishing. If it is broken by accident, it can also be repaired by welding. If you like the style, you can change it in a jewelry store or sell it directly as gold. If it is fake gold, none of this can be done.
