This note describes transparent feldspar from Tanzania displaying blue adularescence, marketed since mid-2004 as Tanzanian moonstone. The material is identified as albite (peristerite), and its physical and chemical properties are reported. The blue sheen is attributed to Tyndall scattering. Microscopic examination reveals white, parallel, needle-like inclusions.
