14k gold itself has not only the gorgeous golden color like gold, but also the hardness that pure gold does not have. So choose 14k gold for customization, which is a universal metal that is not bound by pure gold or inlaid gems.

Because 18K gold contains 25% other metals, it can be made into different colors such as white, yellow and rose red, which are called white 18K gold, 18K rose gold respectively. Compared with 14K gold, it has various colors.

Five, different maintenance skills:
