17.25 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent 17.25 carat oval grey moonstone awaits collectors and designers at The Natural Gemstone Company, a true example of classic elegance and natural charm. Measuring 19.65 x 14.61 x 8.47 mm, this oval cabochon has been shaped and polished to bring out the stone body and surface luster, giving you a piece that sits comfortably and looks substantial in any jewelry setting. The cabochon cut is the ideal artisanal form for moonstone, as it emphasizes the soft internal glow and smooth dome that so many admirers seek. With a clarity grade recorded as very very slightly included when evaluated at eye level, this moonstone presents excellent transparency and minimal inclusions that are only visible under careful inspection, preserving an overall clean and tranquil appearance. The color intensity is medium, providing a gentle grey tone that complements a wide palette of metals and accent stones, and the polish is excellent, reflecting the care and skill applied during the final finishing stages. Importantly, there has been no enhancement to alter color or clarity, so you receive a gem in its natural state, direct from Ceylon Sri Lanka, a source known for yielding fine moonstones with subtle beauty.

For jewelry design and wearable art, this moonstone offers versatility and a serene visual presence that adapts to both modern minimalist and vintage inspired aesthetics. Its substantial carat weight and comfortable dimensions make it an excellent centerpiece for a statement ring, where the oval cabochon will command attention while remaining elegant enough for daily wear. The gentle grey hue and medium color intensity are particularly flattering when paired with warm metals such as yellow gold or rose gold, which introduce a soft contrast that enhances the gem warmth, and the same stone also creates a refined monochrome effect when set in white gold or platinum. For a pendant, the depth and dome of this cabochon will catch ambient light and present a calming focal point against the skin. Designers may choose a bezel setting to protect the cabochon margin and highlight the smooth contour, or an open gallery design to allow more light to interact with the interior. Gemstone accents such as small white diamonds or champagne colored sapphires can frame the moonstone and add brilliance while maintaining the primary stone character. Custom commissions will benefit from the stone dimensions, allowing gem setters to plan prongs and bezels that complement the 8.47 mm depth and ensure secure fit.

At The Natural Gemstone Company we value transparency and the story behind every gem, and this Ceylon origin moonstone carries a heritage of careful mining and skilled lapidary work. No treatments have been applied, which means you are investing in material that displays its natural qualities, with the cabochon form amplifying its intrinsic glow. Care for this moonstone with simple and mindful steps, as moonstone responds best to gentle handling, avoiding harsh chemicals and extreme temperature changes, and cleaning with mild soap and warm water followed by drying with a soft cloth will preserve the excellent polish. When designing with this stone, consider protective settings for active wear to prevent abrasion to the cabochon surface, and remember that a secure bezel or protective prong arrangement will maintain the gem beauty for generations. Whether you are a jeweler selecting a distinctive centerpiece, a collector seeking a fine example of Ceylon moonstone, or a private client commissioning a bespoke piece, this 17.25 carat translucent grey moonstone represents a refined balance of size, clarity, and natural charm, backed by the expertise and care of The Natural Gemstone Company.
