2.62 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

This 2.62 carat marquise shape blue flash moonstone from Ceylon Sri Lanka exemplifies the qualities that discerning buyers seek, with dimensions of 13.59 x 6.19 x 4.13 mm, a cabochon cut, a clarity grade of very slightly included as evaluated at eye level, light color intensity, and an excellent polish. The stone is untreated, with no enhancement, which preserves its natural character and contributes directly to its market value. As presented by The Natural Gemstone Company, this specimen displays a vivid blue flash across its surface that is the result of its internal microstructure. Moonstone adularescence arises from extremely thin, alternating layers of feldspar within the crystal, which scatter and interfere with incoming light, creating a dynamic sheen that appears to float beneath the surface. The marquise cabochon shape has been carefully chosen and executed to maximize this optical effect, allowing the blue shimmer to travel along the length of the stone and to reveal subtle variations as the viewer or wearer changes angle.

For the educated buyer, the combination of factors here defines rarity and desirability. The blue flash is a prized attribute among moonstones, and Ceylon provenance is historically associated with cleaner material and a purer, more saturated adularescence. Very slightly included clarity at eye level indicates that the stone is essentially eye clean, offering strong visual appeal without compromising durability. The cabochon cut and excellent polish are critical for moonstone, because faceting would destroy the layered structure that produces adularescence, whereas a high quality cabochon enhances it. Light color intensity provides a delicate and versatile palette, making the gem well suited for refined jewelry designs, particularly solitaire rings and elegant pendants where the optical play can be showcased. No enhancement further elevates this moonstone for collectors and connoisseurs who prioritize natural state and provenance. In summary, this marquise blue flash moonstone combines scientifically explainable optical phenomena, precise cutting and finishing, and respected origin, making it a compelling choice for buyers seeking both aesthetic distinction and intrinsic gemological integrity.
