10.00 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

In the cool layered bedrock of Ceylon where ancient rivers once carved terraces through crystalline schists this yellow moonstone began its long patient journey, formed where feldspar twins intergrew under low grade metamorphism, the mineral slowly organized into the soft shimmery layers that give moonstone its whispering glow. Local miners in Sri Lanka, working deposits that have been known and respected for generations, read the rock like a map, taking only select pieces of rough that promise translucence and an even tone, and the rough that became this gem was chosen with that same quiet care. This single translucent 10.00 carat oval moonstone measures 16.09 x 11.67 x 7.11 mm, a balanced size that feels substantial in the hand yet elegant on a finger or pendant. Its faint yellow color carries the suggestion of late afternoon light trapped in a pool of glass, and the translucency allows light to move through the stone rather than simply reflecting off the surface. Tiny natural inclusions, very slightly included when evaluated at eye level, are part of the stone is history, natural fingerprints that tell of growth and change over geological time rather than detracting from the gem is calming presence.

When the rough arrived at our workshop the decision to fashion it as a cabochon was intentional, the rounded oval silhouette chosen to honor the stone is internal structure and to present a smooth luminous face that breathes with soft sheen. Cabochon cutting is the traditional form for moonstone, a cut that displays adularescence and the subtle interplay of light that defines the gem, and the cutter preserved the depth with a domed profile that respects the dimensions of 16.09 x 11.67 x 7.11 mm while safeguarding durability for daily wear. The clarity grade of very slightly included was evaluated at eye level by our gem specialists, and the surface received an excellent polish that yields a mirror like finish without the need for any enhancement. There has been no heating, coating, or other treatment applied to alter the stone is natural character, the color intensity remains faint and honest, and the translucent body is presented exactly as the earth created it. At The Natural Gemstone Company we work closely with skilled cutters who understand that a gem is both a physical object and a piece of narrative, and the result for this moonstone is an object that reads as both mineral and memory.

For jewelers and designers the oval cabochon shape lends itself to a variety of settings, from a classic bezel that protects the rounded edges and emphasizes the gem is smooth silhouette, to an open back pendant that allows light to pass through and plays with translucency, to a statement ring where the 10.00 carat weight gives presence without overwhelming.
