Is it better to buy a pearl ring or a tourmaline?

Tourmaline is good. Tourmaline is a kind of tourmaline with rich colors, with high grades of colorless, rose red, purple red, green and blue. The brighter the tourmaline color, the higher its value, its hardness is about 7.5, and it contains bubble inclusions. At the same time, it is precisely because of the variety of tourmaline colors that it will bring a feeling of peace of mind and relaxation to the wearer, which can adjust the wearer's mood and broaden his mind. Tourmaline is hard but fragile, so wear and tear must be avoided.
