黑碧玺

Black tourmaline is a member of the tourmaline mineral. It is actually a black tourmaline rich in iron. It is a complex borate and belongs to crystalline minerals. Because of the variety of colors of tourmalines, there are some good-looking colors, so black tourmalines are generally less used to make jewelry. Although black tourmaline has the same physical properties as other color tourmalines, it is dark and not translucent, so it is not as popular as its other brothers and sisters. The market value of black tourmaline is not too high, but there are also small jewelry used to make bracelets.

Unlike obsidian, obsidian is a non-crystalline gemstone that is a silica semi-colloidal ore body. It is a kind of glass formed in a natural environment, usually formed by rapid cooling of volcanic lava. Obsidian is usually black in color, but it can also be seen in brown, gray and a small amount of obsidian in red, blue or even green materials. Although the color of obsidian is black, the obsidian as a jewel generally has a rainbow effect. Therefore, its color is changed, not the same black, and the black tourmaline is pure black.
