The necklace is made of 18k gold and platinum.
In terms of material characteristics, platinum necklace and 18K gold necklace have their own advantages.
1. In terms of hardness, the hardness of 18K gold and platinum is relatively high, but in comparison, the hardness of 18K gold is slightly better, so 18K gold necklaces generally do not break due to careless pulling.
2. In terms of purity, the purity of platinum is very high, up to 95%, while 18k platinum is composed of 75% gold and other metals, so the purity of platinum metal is higher than that of 18K gold. In this respect, most consumers will prefer metal ornaments with high gold content.

3. In terms of metal color, platinum has a natural white metallic luster and never fades, which is very suitable for long-term wear. 18k gold has various colors, such as platinum, gold and rose gold. However, part of the luster of 18K metal is produced by electroplating, which will fade with the extension of wearing time, so it is necessary to go to the relevant jewelry store for re-electroplating.
4. In terms of price, platinum is a rare natural precious metal, and 18k platinum is a synthetic metal, so there are some differences in price between them, and the price of platinum will be slightly higher.
In fact, from the difference between the two, platinum necklace and 18K gold necklace have their own advantages, and we can't directly say which material is good or not. Some international jewelry brands have introduced many exquisite necklaces made of platinum and 18K gold, which have rich meanings and novel styles.
