Product｜Blue-green Tourmaline・Blue Tourmaline Quality｜Natural blue-green tourmaline from Brazil. Its color is sea green blue. The pixel lathe polishing technology is used to divide the entire blue-green color scale into grids and layers on the gem table, which is a very clever design and polishing technology! Speaking of Brazil, it is a country rich in tourmaline. Currently, most of the blue-green tourmalines are exported from Afghanistan, and the quality is quite unreliable. It is often heard that there are cases of optimization. However, this color of tourmaline has been popular in the Brazilian tourmaline market for a long time, and the sales and docking are relatively mature, and the quality is impeccable. It is worth noting that this kind of blue-green tourmaline does not contain copper, so even if the blue color is a bit similar or even very similar, it is not Paraiba Tourmaline, and has no connection with it. The price is still set according to their respective market prices. And this can also be a cheap version of electric blue tourmaline. Tourmaline has a high Mohs hardness of 7.5~8. It can withstand daily scratches, but it is very afraid of falling. Its corners are brittle, so you need to pay more attention when setting and wearing it. Clean｜VVS2 - Very slight inclusions, which are still invisible to the naked eye even if a non-professional uses a 10x magnifying glass.
