This brand is the top gem brand in South America, boss. But there is something wrong with your question. It depends on what material, what weight and what color. I saw this brand of things in his shop, only a few hundred, and the starting price of small things was several thousand baht. If your things are beautiful and big, only a few hundred dollars, then it is probably not a real stone. The price of Thai baht to RMB is 3: 1, and that store has 600,000 RMB worth of gems. This brand is definitely the top brand in the gem industry.
