The emerald cut — a rectangular format with cut corners and parallel step facets on the crown — is an unconventional and highly distinctive presentation for moonstone, where the broad horizontal steps provide a uniquely architectural canvas for the adularescent phenomenon. This 10.84 ct emerald-cut moonstone from India displays a near-colourless body with a vivid, polychromatic adularescence — blue, orange, and pink simultaneously — visible across the broad rectangular table in a flowing, distributed wash of natural colour. At approaching 11 carats, this is among the most substantial faceted moonstones in this collection; emerald-cut moonstone of this size and adularescent quality is an unusual and distinctive acquisition for the collector who values both extraordinary size and an unconventional lapidary presentation. Natural moonstone (orthoclase feldspar). Weight: 10.84 ct | Origin: India | Cut: Emerald | Dimensions: approx. 19.2 × 15.4 mm
