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

This piece is a translucent blue flash moonstone, marquise shape, weighing 2.36 carats, with precise dimensions of 14.93 by 6.07 by 3.55 mm. The cutting style is cabochon, executed to emphasize the stone volume and the internal optical effects typical of quality moonstone material. The clarity grade is very very slightly included, evaluated at eye level, and the color intensity is classified as light, attributes that contribute to the gemstone refined visual balance. The surface has been given an excellent polish, which enhances both the tactile quality and the optical performance, and the stone has undergone no enhancement. The stated origin is Ceylon Sri Lanka, a source with a long established reputation for producing moonstones of fine character, and the opal type is White Opal.

Optical behavior is central to the character of this stone, with a pronounced adularescence that manifests as a soft, floating glow appearing to move across or beneath the surface of the cabochon. This blue flash adularescence is most active when the stone is viewed in raking light or when it is gently tilted, producing a sensation of depth and motion as the luminous band sweeps from one end of the marquise to the other. The translucent body allows the light to interact with the internal microstructure in a way that produces a clean and cool blue sheen, while the light body color maintains a delicate and elegant overall presence. The cabochon cut is intentionally low in profile, with smoothly contoured surfaces that allow the adularescent layer to remain visually unobstructed, and the excellent polish ensures that the luminous effect is not interrupted by surface interference.

As a selection for a high end gemstone collection, this marquise blue flash moonstone offers a combination of rarity in form, optical refinement, and provenance. The marquise cabochon shape is relatively uncommon for moonstone, lending the piece a distinctive silhouette that photographs and displays well in both bespoke jewelry and curated mounted presentations. The combination of very very slight inclusions at eye level, light color intensity, and a clean blue adularescence produces a stone that reads as both delicate and striking in quality. The Sri Lankan origin provides a documented geographic context, useful for provenance records and for collectors who prioritize known sourcing. The Natural Gemstone Company presents this moonstone as an example of natural material retained in its original state, with no treatments applied, and with finishing that respects the optical character of the material. For collectors seeking a piece that balances gemological clarity, visual movement, and refined cut execution, this marquise cabochon blue flash moonstone is well suited to serve as a centerpiece or as an accent within a high end collection.
