This Rainbow Garnet from Nara Prefecture, Japan, showcases a vibrant array of colors, with flashes of gold, pink, and orange. Its striking iridescence results from thin, reflective layers within the garnet's crystal structure, causing light to diffract and produce its signature rainbow effect. The geometric cut enhances the gem's natural brilliance, making each angle display a slightly different play-of-color. As one of the rarest garnet varieties, specimens from this region remain highly coveted among collectors for their unique optical properties and limited availability.
What makes these even more special is the insight from our supplier: "The guy who polished them will no longer be doing that, so what you have and what's left in Japan is all there will be.'".... No more...Guy is very elderly. When he polished them he was adjusting angles so the rainbow is visible not just from the top but even from the side. He planned every stone to give it maximum rainbow performance"
