[Koshu Precious Stone Kiriko] Spodumene 14.070ct《Collaboration》Loose with emblem
Spodumene comes in a variety of colors, including pink, green, yellow, and clear. Pink is Kunzite, which is particularly famous among spodumene. Green is green spodumene and hiddenite. Yellow is also commonly known as triphane. Spodumene is said to be difficult to cut because it is a cleavage-prone stone. Beautifully cut spodumene is the culmination of the cutter's skill. Enjoy the pleochroism, which allows you to enjoy different hues depending on the angle you look at it from, and the gorgeous sparkle that comes from the doubling property.
This is a loose spodumene stone from Koshu Kikiseki Kiriko, a collaborative work between Shimizu Kikiseki and Yoichi Fukasawa . This Koshu Kikiseki Kiriko was created by two master craftsmen, Yukio Shimizu, president of Shimizu Kikiseki, and Yoichi Fukasawa, president of Jewelry Craft Fukasawa. The faceted surface was handled by Shimizu, and the cut surface by Fukasawa. A special patch is included.
