16.89 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent grey moonstone, weighing 16.89 carat, oval shape, measures 17.62 by 13.15 by 10.07 mm, cabochon cut, with a clarity grade of very very slightly included as evaluated at eye level, medium light color intensity, and an excellent polish. This gem is untreated, no enhancement, and hails from Ceylon Sri Lanka, a source renowned for fine moonstones. The surface shows a silky translucence that allows a soft internal glow to emerge, and the cabochon dome has been finished to reveal a gentle adularescence when viewed in changing light, a classic character of the best moonstones. At 16.89 carat the stone has a substantial presence that will feel both elegant and bold in wearable pieces, and the oval proportions are ideal for a variety of settings, from a statement ring to a pendant centerpiece.

At The Natural Gemstone Company we appreciate the combination of size, quality, and natural origin that this moonstone represents, and we recommend it for designers and collectors who value authenticity and untreated beauty. The excellent polish and careful cabbing make it especially suitable for bezel and halo settings where the stone can be protected and shown to best advantage, and the medium light color intensity means the gem will harmonize with both white and yellow metals. Because there has been no enhancement, the stone preserves its natural character, and our team can advise on mounting options that enhance the adularescent effect while ensuring durability.
