Tourmaline beads are small and have obvious cracks, some of which have affected the transparency. The overall color of tourmaline is not bright enough, but there are many black and dark beads. According to the current general wholesale market price, it is about 40-60 per gram. If you buy it in a shopping mall, the price will increase according to the level of the shopping mall, but generally it will not exceed per gram 100.

Besides, I don't know if the diameter and weight of the landlord's note are right. Generally speaking, the weight of tourmaline bracelets is rarely less than 10g.
