2.05 Ct. Blue Flash Cabochon Adularescence Moonstone from Ceylon (Sri Lanka)

This 2.05 carat marquise blue flash moonstone is a superb example for the discerning collector, measuring 12.87 x 5.37 x 4.91 mm, expertly fashioned as a cabochon to maximize its adularescence. The marquise silhouette is an elegant and relatively uncommon shape for cabochon moonstones, offering a refined elongated profile that sits beautifully in bespoke high-end jewelry or in an assembled gemstone collection. Clarity is graded very very slightly included, evaluated at eye level, meaning that the stone presents an exceptionally clean appearance to the naked eye, with any internal characteristics remaining unobtrusive and not interrupting the play of light. Color intensity is light, allowing the classic blue flash to read clearly against the semi-translucent, milky body. Enhancement status is none, the polish is excellent, and the origin is Ceylon, Sri Lanka, a region renowned for producing moonstones of superior adularescence and consistent quality. For comparative reference, the gem exhibits an opalescent shimmer akin to White Opal, while retaining the distinct schiller and lamellar structure that define authentic moonstone.

The adularescence on this specimen is particularly noteworthy, presenting as a soft, floating blue glow that appears to move across or slightly beneath the surface as the stone is rotated, giving the impression of depth and an inner luminosity. This blue flash is centered and well focused, a sign of fine internal layering and careful cutting, and the cabochon dome has been tuned to present the effect in motion with minimal windowing. For an educated buyer, the combination of a true natural origin, no enhancement, excellent polish, and very very slightly included clarity at this size and shape elevates the stone beyond a common specimen, making it a compelling acquisition for collectors seeking both aesthetic beauty and sound gemological credentials. The Natural Gemstone Company stands behind the provenance and description of this moonstone, and its qualities make it an ideal addition to a high-end gemstone collection or the centerpiece of a custom fine jewelry commission, pairing particularly well with white metals to enhance the cool blue adularescence.
