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

At The Natural Gemstone Company we present a jewel of exceptional character and quiet drama, a translucent blue flash moonstone that reads like a private discovery, reserved for collectors and connoisseurs who seek rarity and refined presence. This is not a common offering, it is a single, beautifully formed oval cabochon from Ceylon Sri Lanka, a region known for producing moonstones with a luminous inner glow and a silky, ethereal depth. The gem is classified within trade descriptions as White Opal type, a designation that highlights its soft, luminous body tone and the way it carries spectral light within its structure. Such specimens are rarely found in this size and with this degree of clarity, and when they do appear they command attention from jewelers and collectors who understand that true rarity is measured not only in scarcity, but in the unrepeatable harmony of size, cut, and optical performance.

Measured and weighed with exacting care, this moonstone totals 6.28 carats, presenting an oval silhouette that spans thirteen point four nine millimeters by nine point nine zero millimeters by six point seven nine millimeters, dimensions that translate into a compelling presence when set into a ring, pendant, or bespoke centerpiece. The cabochon cut amplifies the gemology of the piece, allowing the blue flash to glide across the surface with every turn of the wearer, producing adularescence that reads as both luminous and alive. The clarity is graded as very very slightly included at eye level, a clarity profile that preserves visual purity while carrying the character expected of natural material. The color intensity is light, which in moonstones allows the inner blue flash to read more vividly without overpowering the stone. The polish is excellent, a mirror soft finish that maximizes the stone s interaction with light, and there has been no enhancement applied, ensuring that the gem you receive is wholly natural.

Because of its size and clarity, this moonstone is ideally suited to a statement piece that will be admired for generations. At six point two eight carats and with those expansive dimensions, the stone anchors a design with authority, whether mounted in a classic solitaire pendant that lets the light work its magic unfettered, or set into a custom ring where a low profile bezel highlights the oval face and protects the cabochon while maintaining maximum visual impact. Designers and clients alike will appreciate how the light body color allows metal choices to influence the overall mood, with warm eighteen karat gold creating a vintage, sunlit warmth, and platinum offering a contemporary, cool framework that emphasizes the blue flash. For those seeking contrast, a dark rhodium plated setting will dramatize the adularescence, making the blue flashes appear as if they glow from a midnight sky. Beyond rings and pendants, this gem will translate beautifully into a bespoke brooch or cuff, places where scale and presence are celebrated and the stone can remain the unmistakable focal point.

Ownership of a piece like this places you among an elite few who can claim a gem with such unambiguous character and provenance. We intentionally offer a highly limited selection of single stones of this quality, because rarity is diminished when abundance follows. The moonstone s origin is Ceylon Sri Lanka, acknowledged across the trade for producing specimens with captivating internal light, and at The Natural Gemstone Company we stand behind every detail of our descriptions and assessments. If you wish to commission a setting, our atelier can translate your vision into a bespoke creation, working with trusted master setters who specialize in preserving the integrity of cabochon cut stones, and who understand how to balance protection with the need to present the gem as the solitary star of the piece. For private consultations, secure viewings, and to discuss custom design options, we invite you to contact us so that this remarkable White Opal type moonstone can be reserved and brought into a design that befits its singular beauty. Owning this gem is not merely a purchase, it is an invitation to join a circle of collectors who prize authenticity, provenance, and the rare pleasure of wearing something utterly unique.
