12.61 Ct. Peach Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent 12.61 carat oval shape peach moonstone, dimensions of 18.36 x 12.34 x 7.51 mm, cabochon cut, clarity grade eye clean evaluated at eye level, medium color intensity, excellent polish, enhancement no enhancement, origin Ceylon Sri Lanka. As an orthoclase feldspar, this specimen shows soft adularescence that appears as a gentle shimmer beneath the surface, a characteristic that cabochon cutting is intended to maximize. The substantial 12.61 carat weight and generous face up dimensions allow the adularescent glow to read clearly across the surface, making the stone suitable as a principal center for a ring or pendant. Eye clean clarity at normal viewing distance means there are no obvious inclusions to interrupt the light movement, which raises both aesthetic appeal and market value for discerning buyers. The medium peach tone is warm and natural, avoiding the artificial appearance of treated material, and the excellent polish ensures a satiny finish that complements both modern and vintage design languages. Provenance from Ceylon Sri Lanka adds an important provenance factor, as Sri Lankan moonstones are prized for their balanced color and quality, and the absence of enhancement confirms that what you see is entirely natural.

For a custom piece the peach moonstone reads beautifully with both warm metal choices and carefully selected accent gems. An 18 karat rose gold bezel or low profile prong setting will emphasize the peach warmth and create a cohesive tonal composition, while a halo of small brilliant white diamonds or champagne diamonds will introduce scintillation that contrasts with the moonstone satin glow without overpowering it. For tonal harmony consider pairing with morganite or peach sapphire accents, set as shoulder stones or a delicate cluster, to maintain a soft pastel palette. For deliberate contrast choose deep blue sapphires or teal tourmalines placed as side stones to accentuate the adularescence and make the peach sparkle appear more luminous. The oval shape and 7.51 mm depth allow secure settings that sit comfortably on the hand or chest, and the cabochon profile is especially well suited to bezel set styles and artistic open back mounts that show the gem from both sides.
