Jewelry Wholesale

I consulted many diamond institutions and some said that there are anti -counterfeiting codes on the diamonds, and some say no. What is going on?

Recently, I want to buy jade and crystals. Which of these two is better? Who knows, how does jade and crystal form?

Many jewelry stores say that natural crystals have various magical effects, such as helping the recovery of ** disease, prosperity, helping my studies, and even bringing good luck. I wonder if there is an exact scientific basis for this?

Urgent! Dear brothers and sisters to help! I am very optimistic about you!
