The jewelry bought from Fuxiang Jewelry Store is real. Because it is impossible for a store to intentionally sell fakes to consumers and damage its reputation.

Look at the color, according to the different luster and color of gold, we can roughly distinguish pure gold, k gold, real gold and fake gold. In other words, red and yellow gold is the best, with a purity of over 95%, a positive yellow purity of about 80% and a cyan yellow purity of about 70%. Yellow is light gray, and the fineness is about 50%. Therefore, there is a formula of seven green, eight yellow, nine five red, yellow and white with gray and half gold. For jewelry that has been hidden for a long time, there is a saying that copper turns green, silver turns black and gold never changes color.
