Malawi Moonstone 1.640ct Loose Stone

A type of feldspar mined in Malawi, southeastern Africa. It is characterized by fine, rainbow-colored streaks of light appearing within its transparent crystal. While typical moonstone and rainbow moonstone are appreciated for the surface schiller effect, the appeal of those from Malawi lies in how the rainbow light appears to be suspended inside the stone. This rainbow effect is caused by light interference due to slight distortions or layered structures within the crystal, creating an impressive appearance with banded brilliance that spreads in a fixed direction. The contrast between its transparency and rainbow colors is beautiful, and those with particularly vivid coloration are rare with limited production. Please enjoy the unique expression of light in each individual piece.

※ We strive to ensure that the colors in our photos are as close to the actual product as possible; however, appearance may vary slightly depending on lighting during photography or your monitor settings. Additionally, some photos may be taken using a penlight.

※ For products with UV fluorescence photos, images are taken using a 365nm wavelength blacklight. If you use a light with a different wavelength (e.g., around 395nm), the fluorescence may appear weaker or be difficult to see. The blacklight we use can be found here.
