15.81 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

When you are searching for a center stone that feels like an answer to a long held wish, this translucent 15.81 carat grey moonstone from The Natural Gemstone Company is crafted to meet that exact need. Whether your search is for an engagement ring that speaks to quiet sophistication, a pendant that becomes an everyday heirloom, or a rare addition to a discerning collection, this moonstone delivers presence without shouting. Many clients come to us wanting something that balances soft luminosity with a meaningful size and natural origin, and this oval shape gem answers that brief precisely. Its graceful proportions and gentle internal glow create a sense of calm and refinement that works beautifully for someone who values subtlety and substance in equal measure.

This gem measures 20.19 by 15.38 by 7.26 mm, it is cut as a cabochon to showcase the moonstone s unique optical character, and it remains untreated with no enhancement, preserving the purity of its origin in Ceylon Sri Lanka. With a clarity graded as eye clean at normal viewing distance, you will appreciate the smooth, uninterrupted surface and the internal clarity that invites light to travel through the translucent body of the stone. The color presents as a refined grey with an intense color intensity that reads as a soft, ethereal glow rather than a flat neutral, and the polish has been finished to an excellent standard so that the dome of the cabochon reflects softly and evenly. The cabochon cut is deliberately chosen for moonstones because it maximizes the adularescence and the layered sheen that collectors and connoisseurs prize, giving this piece a luminous quality that changes gently with movement.

For the bride or partner seeking an engagement ring that feels unique yet wearable, this moonstone offers a magnificent balance of size and elegance. At 15.81 carat the gem occupies a commanding presence on the finger, while the oval cabochon profile keeps the silhouette smooth against daily wear. Consider a bezel setting to protect the rim and to emphasize the moonstone s serene surface, or a soft halo of fine diamonds to introduce sparkle without overpowering the stone s understated glow. For collectors looking to add a fine Sri Lankan specimen to their cabinets, the lack of enhancement and the documented origin make this an object of provenance and pride. Jewelry designers will appreciate how the intense yet subtle color allows pairing with white metals like platinum or white gold for a contemporary aesthetic, and with warm metals like yellow or rose gold for a vintage or romantic expression. This versatility means the stone adapts to many creative directions, making it ideal for bespoke commissions through The Natural Gemstone Company.
