The reason why online tourmaline is so cheap is that jewelry has always been a precious and beautiful luxury in people's eyes, but some kinds of jewelry look "low-end". Unfortunately, tourmaline is among them. There is actually a big misunderstanding here. Tourmaline is not cheap, but there are too many fake tourmalines on the market now. Tourmaline also has ultra-high-priced varieties, and it is not worse than noble gems!
