3.66 Ct. White Cabochon Moonstone from Ceylon (Sri Lanka)

This exquisite translucent white moonstone weighs 3.66 carats, an exceptional weight for a single cabochon moonstone that immediately communicates premium quality and presence. The oval shape measures 12.46 x 9.26 x 4.53 mm, a generous size that photographs and sets beautifully, while maintaining classic proportions for ring or pendant designs. The cabochon cut is expertly executed to showcase strong adularescence, and the excellent polish allows soft blue and silvery flashes to glide across the dome as the stone moves. Clarity has been evaluated at eye level as very slightly included, which is typical and acceptable for natural moonstone, and the near colorless body tone enhances the play of light rather than obscuring it. Importantly, this gem has received no enhancement, so collectors and connoisseurs can be confident in its natural character and intact optical properties.

For the educated buyer, this moonstone represents an appealing combination of gemological integrity and aesthetic impact, which is why The Natural Gemstone Company features it as a highlight piece. Originating from Ceylon, Sri Lanka, this specimen benefits from a provenance known for producing high quality feldspar group gems, and its translucency coupled with minimal inclusions increases its desirability. The 3.66 carat weight is noteworthy because moonstones at this scale, with such clean appearance and well centered adularescence, are less common than smaller, more heavily included material. This makes the stone suitable for fine jewelry where visual weight matters, offering an elegant presence on the finger without resorting to overly large dimensions. We recommend setting options that protect the cabochon, such as a bezel or halo design in white gold, yellow gold, or sterling silver, which will both complement the near colorless body and preserve the gem for long term wear. At The Natural Gemstone Company we prioritize accurate grading, ethical sourcing, and clear photographic representation, and this white moonstone meets those standards, providing a trustworthy choice for collectors, designers, and discriminating clients seeking a natural, untreated, and visually appealing gem.
