10.10 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

There is one beautiful translucent 10.10 carat oval grey moonstone from Ceylon, Sri Lanka that we are pleased to present, measuring 13.08 x 11.24 x 9.37 mm. This gem is cut en cabochon to best reveal the classic adularescence that moonstone lovers seek, the soft, floating sheen that shifts with movement and light. The body color reads as a cool grey with a gentle warm yellow flash in certain angles, a medium light color intensity that gives the stone a refined and versatile presence. Clarity is graded very slightly included when evaluated at eye level, natural inclusions that add character and depth without interrupting the overall silky appearance. The surface finish is an excellent polish, producing a glass like dome that feels smooth to the touch and reflects light in broad, flattering highlights. Importantly, this moonstone has undergone no enhancement, it is natural and untreated, and its Ceylon origin speaks to a long tradition of fine gemstone material that often shows balanced color and pleasing adularescence.

For design and styling, the generous dimensions and weight of this 10.10 carat oval make it an outstanding choice for a statement ring or a central pendant, while the cabochon dome also lends itself to bold earrings and artisan cuff links. The stone sits beautifully in a bezel setting which protects the edges and highlights the rounded profile, and it also adapts well to low profile prong settings that allow more light to reach the dome. Metals that complement the grey and subtle warm flash include 18k white gold for a modern cool look, yellow gold to bring out the warmer undertones, and rose gold for a soft, romantic contrast. For designers or collectors interested in mixed gem compositions, pairing this moonstone with small accent diamonds or deep blue sapphires can create elegant contrast and draw attention to the luminous center. The substantial depth of 9.37 mm ensures a satisfying sense of presence on the hand or at the throat, while the even oval outline allows for symmetrical mounting and secure bezel work.

At The Natural Gemstone Company we stand behind the natural beauty and provenance of this moonstone, and we are happy to assist with setting recommendations, custom design consultations, and care guidance. Moonstone is durable enough for everyday wear with mindful care, its Mohs hardness is around 6 to 6.5 so it benefits from protective settings and gentle handling to avoid sharp knocks and abrasive surfaces. Clean with mild soapy water and a soft brush, avoid steam or harsh chemicals, and remove jewelry during heavy work to keep the polish and adularescence at their best. Because this stone is natural and untreated, slight inclusions and unique internal structures are part of its charm and make each piece a one of a kind treasure.
