[On sale 7/24 at 10 PM] Malawi Moonstone 1.621ct Loose Stone
A type of feldspar found in Malawi, Southeast Africa. It is characterized by fine, rainbow-colored streaks of light appearing within a translucent crystal. While common moonstones and rainbow moonstones are admired for their surface schiller, the appeal of Malawi-sourced moonstones lies in the way the rainbow light appears to penetrate deep inside the crystal. This rainbow color is created by light interference from slight distortions and layered structures within the crystal,
and the band-like brilliance spreading in one direction creates an impressive appearance. The contrast between transparency and rainbow colors is beautiful, and those with particularly good coloration are rare and limited in production. Please enjoy the unique light expression of each individual piece.
