11.99 Ct. Moonstone from Ceylon (Sri Lanka)

This piece presents a single translucent peach moonstone weighing 11.99 carat, fashioned in an oval outline with dimensions of 19.90 x 14.92 x 5.25 mm. The stone is cut in a mixed brilliant style, and exhibits an intense color intensity with an eye clean clarity grade when observed at eye level. The polish is graded excellent, and there has been no enhancement applied to the gem. Origin is Ceylon, Sri Lanka, and the combination of weight, proportions, and translucency yields a strong, uniform peach tone that reads consistently across the table and crown. The Natural Gemstone Company documents these characteristics to aid exact setting and design decisions.

This moonstone adapts well to a wide variety of jewelry settings, offering flexibility for both classic and contemporary executions. For rings, a low bezel setting will emphasize the stone geometry while providing edge protection for daily wear, whereas a fine prong mounting can increase light entry and accentuate the mixed brilliant cutting style for greater optical return. For pendants and brooches, an open back or partially open gallery will enhance translucency and depth, while a closed back in warm metals will enrich the peach color. Matched halo treatments with small brilliant diamonds or warm colored sapphires will create contrast and apparent size without overwhelming the primary gem, and paired side stones can be used to balance the oval proportions in three stone or tapered cluster settings. The stone scale and depth are suitable for drop earrings, where paired symmetrical mountings preserve movement, and for statement cuff or signet designs where the robust table provides a secure focal plane.

Design and metal choices influence perceived color and character, with rose gold and yellow gold tending to heighten the warm peach tones, and platinum creating a cooler, modern contrast. Given the natural, untreated state and the feldspar family hardness range, protective settings such as bezels, chemise crowns, or raised galleries are recommended for rings expected to receive frequent wear. Ultrasonic cleaners and harsh chemical exposures should be avoided during routine care, and cleaning with a soft brush, mild soap, and warm water will preserve the polish and color. The Natural Gemstone Company can provide additional technical drawings and mounting recommendations to integrate this 11.99 carat Ceylon peach moonstone into bespoke or production jewelry projects.
