3.48 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful opaque 3.48 carat round shape blue flash moonstone is presented with precise dimensions of 9.69 by 9.68 by 5.25 mm, showing a classic domed cabochon cut that maximizes the stones adularescence. The cabochon profile is very well centered and polished to an excellent finish, allowing the blue flash to move smoothly across the surface when viewed in different lighting. Clarity is graded as very slightly included, evaluated at eye level, which indicates minute internal features that are typical for natural moonstone and do not interrupt the overall visual effect. Color intensity is very light, which in combination with the blue adularescence creates a delicate, ethereal appearance sought after by collectors and designers. There has been no enhancement or treatment to alter this gem, and its origin in Ceylon Sri Lanka is an important quality marker, as Sri Lankan moonstones are historically prized for fine adularescence and clean body tones.

For the educated buyer this moonstone offers a compelling combination of natural provenance, optical character, and lapidary quality, making it well suited for both bespoke jewellery and premium collections. The 3.48 carat weight and near 10 mm diameter sit in a desirable size range that allows for striking pendants or rings while retaining affordability relative to larger cabochons. The excellent polish enhances light return and the perceived depth of the blue flash, while the very slightly included clarity assures natural origin and stability, attributes that add to long term value. Because the stone is unenhanced and from Sri Lanka, it carries provenance value that informed purchasers prioritize, as treatments can affect future resale and appraisal. Practical considerations for setting include using a bezel or protective setting to preserve the domed surface and to reduce exposure to knocks, while standard care involves avoiding harsh chemicals and ultrasonic cleaners.
