The spectral adularescence of this 9.84 ct radiant-cut moonstone from India is the most comprehensive multicolour display in this collection — a simultaneous green, blue, and pink adularescent wash distributed across the broad rectangular-radiant face, producing a distributed rainbow effect that is entirely natural and arises from the moonstone’s internal feldspar layering. The pale, near-colourless body provides maximum contrast for the multicolour display, which shifts and redistributes as the viewing angle changes, with different spectral colours dominant at different angles. At approaching 10 carats, this is a large and impressive faceted moonstone with a colour range and optical complexity that is genuinely exceptional in the moonstone world. Natural moonstone (orthoclase feldspar). Weight: 9.84 ct | Origin: India | Cut: Radiant | Dimensions: approx. 17.2 × 14.8 mm
