12.73 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This translucent white moonstone of 12.73 carat, measuring 17.19 x 13.38 x 7.52 mm, is cut as a high domed oval cabochon to maximize adularescence and surface brilliance. The cabochon profile exhibits a smoothly graduated dome and a precise, symmetrical oval outline, with proportions that create a commanding presence while preserving light play across the table. The stone is evaluated as eye clean at normal viewing distance, allowing its internal structure to present a clean, even glow without visible inclusions disrupting the adularescence. Color intensity is near colorless, offering an essentially neutral body tone that enhances the white schiller and permits versatile metal pairings. The polish is excellent, the surface free of cabochon tool marks, and the piece is completely natural with no enhancements, sourced from Ceylon Sri Lanka where traditional lapidary techniques emphasize orientation and cutting to reveal the finest adularescent effect.

For a statement piece, the dimensions and clarity are decisive. At 17.19 mm length and 13.38 mm width the stone occupies a pronounced visual field, while the 7.52 mm dome provides depth and luminous movement when worn. The eye clean clarity ensures uninterrupted adularescence, making this moonstone ideal for a solo bezel set pendant, a bold cocktail ring, or a centerpiece brooch where the dome can catch and reemit light with each motion. The near colorless body allows designers to select white gold or platinum for a cool, ethereal presentation, or yellow and rose gold for warm contrast against the white schiller. The Natural Gemstone Company presents this cabochon as a collector quality specimen, ready for secure setting and long term wear, with its excellent polish and natural origin ensuring authenticity and enduring visual performance. For clients seeking a significant, wearable gemstone with technical merit in cut, clarity, and provenance, this 12.73 carat Ceylon moonstone offers a rare combination of scale and optical purity suitable for a memorable signature piece.
