[9/22, 10 PM Sale] Malawi Moonstone 4.333ct Loose Gemstone
A type of feldspar mined in Malawi, in southeastern Africa. It is characterized by fine, rainbow-colored light that appears in streaks within its transparent crystals. While typical moonstones and rainbow moonstones are enjoyed for their surface sheen, the allure of the Malawi variety lies in the appearance of the rainbow light contained deep within the stone. This rainbow effect is created by light interference caused by slight distortions or layered structures inside the crystal, creating an impressive, banded brilliance that spreads in a specific direction. The contrast between its transparency and the rainbow colors is beautiful, and those with particularly vibrant coloration are rare, with limited production. Please enjoy the unique expression of light in each individual stone.
