153.83 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

Presenting a remarkable grey moonstone from The Natural Gemstone Company, a single translucent oval weighing 153.83 carat, with dimensions of 14.52 x 12.48 x 11.65 mm, cut as a smooth cabochon to showcase the stone core and surface sheen. This gem displays a light grey body color with subtle depth, and a translucent clarity that invites light to travel through the material in a soft glowing manner. The overall effect is elegant and understated, perfect for clients who desire a large statement piece that is refined rather than flashy. The excellent polish enhances the surface reflection, while the cabochon dome allows any internal play of light to present without interruption, making this moonstone an excellent candidate for a central piece in rings, pendants, or bespoke collectors pieces.

From a gemological perspective this moonstone is a fine example of Sri Lankan material, originating from Ceylon, a source historically prized for its clean, well crystalized feldspar specimens. The clarity grade has been assessed as very slightly included, evaluated at eye level, which means the stone is visually clean to most observers while still retaining natural characteristics that confirm its authenticity and natural origin. There has been no enhancement, so what you see is natural color and structure, with an excellent polish applied by skilled lapidary hands to maximize feel and light behavior. The cabochon cut emphasizes the moonstone effect known as adularescence, a soft sheen that appears to float across the surface when moved under light, and although this specimen shows light color intensity, the translucence and sheen together create a serene and luminous presence that can read differently under warm or cool lighting conditions.

For design and care considerations this 153.83 carat oval is substantial enough to be the focal point of high end jewelry, where the smooth dome will sit comfortably against the skin and interact beautifully with surrounding metal work. Consider settings that protect the girdle and top surface, such as a bezel or partially bezel set frame, to maintain the integrity of the cabochon while allowing light to enhance its adularescence. The grey tone pairs exceptionally well with warm metals if a soft contrast is desired, and it also harmonizes with white metals when a cooler, modern aesthetic is preferred. For collectors the unenhanced origin from Ceylon adds provenance value, while the very slightly included clarity and excellent polish make the piece both natural and finished to the standards expected by connoisseurs. Care is straightforward, avoid harsh chemicals and ultrasonic cleaners, clean gently with mild soapy water and a soft cloth, and store separately to prevent scratching from harder gems. As a representative of The Natural Gemstone Company I am pleased to offer this distinctive moonstone to clients who appreciate a combination of size, natural character, and expert lapidary finishing, and I am available to discuss custom design options, certification queries, and secure shipping arrangements.
