10.57 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

When you are searching for a gemstone that finally feels like the answer to a long held vision, this orange moonstone brings that sense of completion. Many customers tell me that they want a stone that is rare enough to feel special, yet wearable enough to become a treasured everyday piece. Whether you are planning an engagement ring that steps away from the expected, designing a bespoke pendant that captures warm light, or adding a standout specimen to a curated collection, this stone meets those needs with confidence. Offered by The Natural Gemstone Company, this is a single, translucent 10.57 carat oval moonstone, presented in a classic cabochon cut that emphasizes a soft luminous glow. The dimensions are 16.00 x 12.05 x 7.31 mm, and the stone displays a medium intense orange hue that reads as warm and inviting under natural light. The clarity is graded very very slightly included evaluated at eye level, and the surface shows an excellent polish that gives the piece a silky, reflective finish. There is no enhancement, and the origin is Ceylon Sri Lanka, which is known for producing moonstones with refined color and good optical character.

As a specialist I like to describe how each technical attribute enhances the gem for practical use. The cabochon cut makes the dome shape ideal for showcasing the moonstone effect known as adularescence, where internal layering creates a gentle inner glow. Because this stone is translucent rather than fully transparent, light diffuses beautifully across the surface, giving it depth and a soft, almost satiny appearance. At 10.57 carats and measuring 16.00 by 12.05 by 7.31 millimeters, the proportions are generous enough to serve as a confident center for a ring, a statement oval in a pendant, or a prominent component in a designer brooch. The clarity grade of very very slightly included at eye level means that inclusions are minimal and do not distract from the overall visual presence, and the excellent polish enhances the smooth, reflective dome so the color and internal sheen read consistently from different angles. Because there has been no enhancement, you are receiving the stone in its natural state, and the provenance from Ceylon Sri Lanka adds a layer of geological and ethical transparency that many customers appreciate.

Practical considerations matter when you are commissioning a piece or evaluating a collectible, and this moonstone is versatile while still demanding thoughtful handling. Moonstone is softer than many faceted gemstones, so I recommend protective settings such as a secure bezel or a partially bezeled halo to shield the edges while still allowing light to animate the cabochon surface. A warm metal choice such as rose gold will complement the orange tonality and deepen the perceived warmth, while yellow gold will harmonize with the classic palette and silver will create a modern contrast. The measurements 16.00 x 12.05 x 7.31 millimeters sit comfortably within many standard mounting templates, so a jeweler can typically set this cabochon with minimal alteration to a custom design. For collectors who value provenance and condition, the absence of enhancements and the excellent polish increase the stone s long term desirability and ease of resale when that becomes a consideration. I can advise on ring shank sizes, pendant bails, and recommended protective measures, and I can facilitate matching the stone to certified settings that preserve both its beauty and its structural integrity.
