1.72 Ct. Moonstone from Ceylon (Sri Lanka)

There are gemstones, and then there are singular treasures that appear only rarely, stones that feel destined for the hands and minds of collectors and creators who understand true rarity. This transparent blue flash moonstone of 1.72 carats is one such treasure, a piece we at The Natural Gemstone Company present with the quiet confidence of something both exceptional and scarce. Its provenance is Ceylon Sri Lanka, a source renowned for producing moonstones with the most vivid and pure adularescence, and this specimen shows that legacy in every shifting flash of blue. Offered without enhancement, with an excellent polish and a clarity graded as very slightly included at eye level, it arrives to the bench or the vault as a raw invitation to bespoke artistry, an opportunity to claim a gem that is not mass produced, but selected and preserved for the discerning few.

Beyond provenance and polish the physical form of this moonstone makes it supremely suited to custom jewelry. The oval shape in a precise 9.38 by 7.03 by 4.75 millimeter profile combines graceful presence with practical versatility. At 1.72 carats it retains the visual impact to serve as the crown of a ring, the heart of a pendant, or the centerpiece of a cuff or bespoke brooch, while remaining comfortable for everyday wear. The mixed brilliant cut has been executed to balance scintillation and the unique blue flash, so that as light moves across the surface the internal adularescence plays and blooms rather than dissipating. Designers will appreciate how the oval silhouette allows for a secure four or six prong setting or a custom bezel that highlights the gem without concealing its luminous core, and how the length to width ratio lends itself to both classic and contemporary compositions.

For those commissioning custom work the stone rewards imagination and precision. Its faint body color provides a neutral and elegant backdrop that allows accent stones to introduce contrast or harmony, diamonds for clarity and fire, sapphires for echoing blue, or subtle colored melee for modern accents. The mixed brilliant facet arrangement enhances brilliance along the long axis, which means the gem reads larger than its carat weight might suggest when set vertically on a ring or horizontally in a pendant. The very slightly included clarity at eye level ensures that the gem remains visually clean to the unaided eye, while offering a character that certifies natural origin and authenticity. The excellent polish amplifies the blue flash, so settings that allow light to enter and reflect will best display the moonstone nature that collectors prize. For bespoke ateliers and private clients seeking a statement that is both wearable and museum worthy, this moonstone is a rare canvas.

Owning this moonstone is to join an exclusive circle of collectors and clients who commission the extraordinary rather than the ordinary. The Natural Gemstone Company presents this gem as a limited offering, a single specimen that will not be duplicated, and we work directly with designers and private clients to ensure the final piece reflects the singularity of the stone. Because it is unenhanced and responsibly sourced from Ceylon Sri Lanka it carries provenance that matters, and the combination of size shape and cut makes it immediately adaptable to custom designs without compromise. If you imagine a ring that will be handed down through generations, a pendant that defines a personal signature, or a bespoke commission that marks a milestone, this moonstone is an invitation. We welcome inquiries from clients who wish to reserve the stone, to discuss design possibilities, or to arrange private viewing and consultation with our lapidary and design partners.
