8.78 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

If you are searching for a singular stone that will finally end your search for the perfect engagement stone or the rare centerpiece to add to a collector cabinet, this grey moonstone is designed to answer that need. This is a translucent oval moonstone weighing 8.78 carats, presented in an elegant cabochon cut that allows its inner glow to breathe, and its measurements of 13.89 x 9.95 x 8.63 mm make it a substantial and wearable size for both rings and pendants. Many customers tell us that they want a gem that feels refined yet quietly distinctive, something that reads as timeless rather than trendy, and this moonstone checks those boxes with its gentle grey tone and light color intensity that sits beautifully between soft neutrality and expressive presence. The shape and size lend themselves to classic solitaire rings, graceful bezel settings, and striking bespoke creations, so whether your priority is everyday wearability or making a memorable statement for a special occasion, this single gem provides the versatility you are looking for.

As a gem professional I appreciate when a stone brings both character and honesty, and this moonstone delivers on both. Its clarity grade is very slightly included, evaluated at eye level, which means it carries natural inclusions that speak to its authenticity while remaining visually clean and appealing to the naked eye. The cabochon cut and excellent polish work together to reveal a smooth surface and a soft inner sheen that catches light in a way faceted stones do not, creating a living, lunar quality that shifts with movement and ambient light. There is no enhancement, the stone is fully natural, and its origin in Ceylon Sri Lanka situates it among some of the most respected sources for fine moonstone material. For practical considerations the dimensions and depth provide ample table area for jewelers to set the stone securely, and the cabochon profile makes it ideal for bezel work, low profile rings, or dramatic open settings that allow light to play through the body of the gem. Collectors will value the stone for its provenance and natural state, while a couple commissioning an engagement ring will find in this moonstone a rare and personal alternative to traditional choices.
