Tanzanian Bicolor Zoisite 1.136ct Loose Stone with Certification
Zoisite is available in a rich variety of colors and was named after the Slovenian mineral collector, Sigmund Zois. Tanzanite is actually a type of zoisite. Like tanzanite, its charm lies in its "pleochroism," where it appears to change color when viewed from different angles. This particular piece is a relatively rare bicolor zoisite.
This is a highly transparent bicolor zoisite from Tanzania. It comes with a certificate of authenticity.
