0.36 Ct. Rainbow Moonstone from Ceylon (Sri Lanka)

One transparent 0.36 carat oval rainbow moonstone, dimensions 4.88 x 4.58 x 3.15 mm, presents a finely executed mixed brilliant cut that combines a brilliant facet arrangement on the crown with a calibrated pavilion to maximize light return and adularescence. The cutter has maintained a measured pavilion depth relative to the table size to preserve dispersion without sacrificing face up brilliance, while the excellent polish ensures minimal surface diffusion of light. Clarity is reported as very slightly included, evaluated at eye level, which in this size contributes character without compromising optical performance. Color intensity is light, allowing the intrinsic rainbow sheen to read clearly against a transparent body tone, and the gem is unenhanced, originating from Ceylon, Sri Lanka. The mixed brilliant faceting delivers scintillation across the table and along the facets, and the oval outline yields an elegant length to width ratio suitable for both solitaire and framed designs, the 3.15 mm depth permitting low profile settings when required without excessive overhang of the girdle.

This stone adapts readily to a variety of custom jewelry executions, and The Natural Gemstone Company can advise on mounting strategies that preserve the stone geometry and optical behavior. For high security and contemporary aesthetics, a thin bezel with an inner channel profile will protect the girdle while maintaining the visual outline, an ideal solution for pendants and everyday rings. For maximum light interaction, a four or six micro prong setting elevates the crown to expose the table to incident light, which enhances the spectral flashes typical of rainbow moonstone. Halo settings with melee diamonds or colored accents will increase perceived size and contrast the light body color, while east west orientation in a slim band provides a modern silhouette. The mixed brilliant pavilion also supports tension settings for a floating effect when precise seat geometry is fabricated. For earrings or matching pieces, consider asymmetrical pairings that use small complimentary stones to balance the lightness of color. All custom work can include recommendations on metal selection, with platinum and 18 karat white gold preserving cool tones, and 18 karat rose gold adding warm contrast that emphasizes the rainbow play.
