[Koshu Precious Stone Kiriko] Tanzanite 2.360ct loose with patch

Tanzanite is a stone that is attractive for its pleochroism, which appears to be a different color depending on the viewing angle. I never get tired of watching the various blue colors such as blue, blue-purple, and ultramarine dancing inside the stones. The name ``Tanzanite'' was given by Tiffany & Co.

This is a loose tanzanite (checkerboard cut x dawn) made by Koshu Takaishi Kiriko, a collaboration between Shimizu Kiseki and Yoichi Fukasawa. It is 10×8mm.

Koshu precious stone Kiriko was created by two masters: Yukio Shimizu, representative of Shimizu Precious Stones, and Yoichi Fukasawa, representative of Jewelry Craft Fukasawa. Mr. Shimizu handles the facets and Mr. Fukasawa handles the facets. A special patch is included.
