[Takeshi Yamamoto] Brazilian Rock Crystal 22mm/48.216ct Loose Stone (Fire Flower)
This is a very beautiful loose stone cut by Yamamoto Takeshi, a first-class gemstone cutter from Yamanashi. The cut is called Fire Flower (fireworks), and it certainly seems like there is an affinity between fireworks sparkling in the night sky and sparkling gemstones. This is a wonderful piece with a delicate sparkle created by the fine cut. This is a size that is quite impressive, at 22mm.
