5.54 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

When you are searching for a gemstone that feels like the final piece of a story, rather than the first draft, this translucent blue flash moonstone from The Natural Gemstone Company is designed to end that search, not extend it. Clients who are looking for an engagement stone that is quietly unique, collectors who prize natural phenomena over synthetic uniformity, and designers who want a centerpiece with depth and movement will all see this moonstone as the perfect solution. At 5.54 carat, this oval shape moonstone has a presence that reads as substantial without overwhelming a thoughtful design. The dimensions of 19.23 by 6.57 by 5.80 millimeters allow for elegant, elongated settings that sit comfortably on a finger or translate beautifully into a pendant. The cabochon cut preserves and highlights the stone s signature adularescence, and the blue flash that appears as you move the stone gives it an almost living quality, responding to light like a private moonlit sky.

For buyers who require clear technical information to feel secure in their choice, this moonstone checks every box that matters. The clarity grade is very slightly included when viewed at eye level, which in moonstones often contributes to a soft internal glow rather than detracting from it. The color intensity reads as medium intense, meaning the blue flash is noticeable and captivating without appearing artificial or overstated. The polish is excellent, giving the cabochon a silky surface that enhances the play of light and improves comfort against the skin. Importantly for discerning collectors and anyone who values natural rarity, there is no enhancement. This moonstone is natural and untreated, sourced from Ceylon, Sri Lanka, a region historically celebrated for producing moonstones with exceptional adularescence and character. That provenance adds to the piece s narrative and to its desirability on the market.

When you imagine this moonstone in a finished piece, think of designs that allow the blue flash to be seen from multiple angles, while protecting the cabochon s smooth dome. A low bezel or a soft scalloped gallery provides security and a modern aesthetic that complements the stone s translucent body. For an engagement ring that emphasizes serenity and personality, pair this moonstone with platinum or white gold to echo the sapphire like flash, or choose warm rose gold to create a poetic contrast that softens the overall look. For pendants and statement earrings, orientation matters, so the 19.23 millimeter length can be aligned vertically for a graceful drop, or set horizontally for a contemporary bar effect. Because of the very slightly included clarity grade, setting the stone close to the skin will make the adularescence more intimate and responsive. Caring for this moonstone is straightforward, but important, keep it away from harsh chemicals and extreme heat, avoid ultrasonic cleaners, and clean it gently with mild soap, warm water, and a soft cloth to maintain the excellent polish over years of wear.
