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

One beautiful translucent 1.41 carat oval shape blue flash moonstone is presented with dimensions of 7.76 x 6.43 x 3.72 mm, cabochon cut, clarity grade very very slightly included, evaluated at eye level, light color intensity, and an excellent polish. This gem displays a distinct blue flash across its domed surface, a desirable adularescent phenomenon that is most visible in well cut cabochons, and the stone is from Ceylon, Sri Lanka. The opal type is White Opal, and the specimen has no enhancement. For buyers seeking a natural, untreated example of classic moonstone character, this piece offers a compelling balance of aesthetic appeal and gemological integrity. The compact oval profile and the measured thickness of 3.72 mm provide enough depth for a strong internal sheen, while the 7.76 by 6.43 mm face up gives a pleasing presence for rings, pendants, and collector cabinets, making it versatile for both jewelry applications and specimen collections.

Carat weight is a primary driver of rarity and value in gemstones, and a 1.41 carat moonstone occupies an important threshold for educated buyers. Moonstones are typically encountered in smaller sizes because of the nature of the feldspar cleavage and the way adularescent layers form, therefore stones above one carat with a strong blue flash are comparatively scarce in the trade. The 1.41 carat weight enhances the gem in two ways, physical presence and market valuation, because price per carat in moonstones often increases progressively with size when color and clarity remain high. In practice this means that a 1.41 carat stone will command a premium over multiple smaller stones that aggregate the same weight, due to the desirability of a single, clean face up adularescence and the aesthetic impact of a larger, uninterrupted surface. For collectors and lapidary designers, this weight makes the gem suitable for central settings in fine jewelry, where the visual scale of the adularescence can be shown off without crowding, and where the single stone narrative is usually more valuable than a cluster of small stones.

Clarity grading of very very slightly included, evaluated at eye level, is a meaningful descriptor for an educated buyer because it speaks to the practical transparency and perceived purity of the stone. Very very slightly included describes inclusions that are minimal and not distracting when the gem is viewed without magnification, which in moonstones often translates to faint needle like inclusions or planar growth lines that do not interfere with the play of light. Because adularescence results from internal layering, some growth related features are natural and acceptable, and a VVS grade at eye level indicates that these features are subtle and do not undermine the blue flash. The cabochon cut is optimized to enhance the sheen, with a domed surface that concentrates and reflects light across the adularescent layers, and the excellent polish ensures maximum surface reflectivity, so that the blue flash reads cleanly across the face of the gem. Together, the cabochon geometry, the clarity profile, and the fine polish create a stone that performs strongly under different lighting conditions, maintaining a visible and attractive blue flash under directional or diffused light.

Origin and treatment status are critical elements for provenance and long term value, and this moonstone is from Ceylon, Sri Lanka, a source with a historical reputation for producing high quality moonstones with attractive adularescence. Stones from Sri Lanka often exhibit cleaner adularescence and a refined sheen, which are characteristics valued by connoisseurs and designers alike. The absence of enhancement is particularly important, because untreated natural color and sheen are preferred by many collectors and by markets that prize natural gem characteristics. The classification as White Opal type may be used in trade to describe the pale body color and luminous quality that aligns this specimen with lighter, opalescent feldspars, and when combined with the documented origin and clear treatment history, it reinforces confidence in the stone as a natural, collectible item. The Natural Gemstone Company stands behind the accuracy of these descriptions, and we present this 1.41 carat blue flash moonstone as a gem that balances rarity, visual performance, and gemological integrity, making it suitable for discerning buyers who prioritize origin, clarity, and the lasting value associated with a naturally beautiful, well proportioned stone.
