[Ref: 12564725] Tanzanite from Tanzania, 0.892ct loose stone
Tanzanite is a captivating stone known for its "pleochroism," displaying different colors when viewed from different angles. Watching the various shades of blue—such as blue, violet-blue, and ultramarine—dance within the stone is truly mesmerizing. Incidentally, the name "Tanzanite" was coined by Tiffany & Co.
This tanzanite also features high transparency.
