19.21 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

Here is a beautiful, natural moonstone that will appeal to collectors and designers alike, a translucent 19.21 carat oval shape grey moonstone measuring 16.80 x 13.24 x 11.66 mm, expertly fashioned with a classic cabochon cut to showcase its smooth, domed surface. The gem carries a clarity grade of very slightly included, evaluated at eye level, which means the stone has only minor internal characteristics that do not detract from its overall beauty but instead confirm its natural origin. The color intensity is medium and presents a serene grey tone that will harmonize with many metals and complementary gems. The polish is described as excellent, producing a bright, even surface that reflects light cleanly and enhances the subtle glow unique to moonstone. Importantly, this moonstone has undergone no enhancement, so you are receiving a genuine, untreated gem from a trusted gem producing region.

This moonstone originates from Ceylon, also known as Sri Lanka, a location renowned for producing fine quality moonstone with appealing color and clarity. The stone displays a gentle, internal shimmer that is characteristic of moonstone adularescence, a soft play of light that moves across the domed surface as the viewing angle changes. Because of its generous weight and pleasing dimensions, this cabochon is particularly well suited to become the centerpiece of a statement ring, an elegant pendant, or a bespoke brooch. The classic oval shape and the smooth cabochon profile allow the adularescence to be experienced fully, and the neutral grey color makes this gem versatile for both contemporary and vintage inspired settings. At The Natural Gemstone Company we value untreated, well cut examples like this one, and we present this stone as an opportunity to craft a distinctive piece that will age gracefully and retain strong aesthetic appeal.

For practical considerations and long term enjoyment, the very slightly included clarity means that daily wear should be mindful and protective, particularly from hard knocks which can chip a cabochon edge or surface. Moonstone responds well to simple care, gentle cleaning with warm water and mild soap, and avoiding prolonged exposure to harsh chemicals and extreme heat. When designing a setting, consider a bezel or protective halo to secure the cabochon while showcasing its smooth contour, or select a low prong setting for rings to reduce the chance of accidental impact to the dome. This stone offers excellent value for designers seeking a natural, untreated focal gem that combines a substantial presence with refined subtlety. Its 19.21 carat weight positions it well for high end custom work, and because it is untreated, it appeals to connoisseurs who prioritize natural beauty and provenance.
