甲州貴石切子

Koshu precious stone cut glass

Koshu Precious Stone Kiriko was developed by applying cutting techniques such as Edo Kiriko and Satsuma Kiriko. It was born from a collaboration between Yoichi Fukazawa of Jewelry Craft Fukazawa and Yukio Shimizu of Shimizu Precious Stone. Koshu Precious Stone Kiriko is made using a cutting method that is a world first, with Fukazawa in charge of the cut surfaces and Shimizu in charge of the facet surfaces. The stunning cuts, full of originality and like works of art, are combined with the individuality of the gemstones to make them truly one of a kind. There are dozens of patterns in total that combine surface cuts such as rose cuts and checkerboard cuts with several types of cut glass, and it is also possible to enjoy the luxury of collecting and arranging stones with various cuts.
