0.52 Ct. Greenish Blue Cabochon Sapphire from Montana

This listing describes one transparent 0.52 carat oval shape greenish blue sapphire with overall dimensions of 5.49 x 4.33 x 2.08 mm. The gem presents a gentle greenish blue hue with light color intensity, offering a subtle and refined tone that is consistent across the stone. The shape is a classic oval, and the gem has been fashioned as a cabochon, producing a smooth domed surface rather than faceted planes. The cabochon form emphasizes the stone body color and internal character, and it measures to a size appropriate for a modest solitary setting or as a harmonious accent component in multi stone jewelry. This sapphire is documented as originating from Montana, and the piece is presented and available through The Natural Sapphire Company.

The cutting and finishing of this sapphire display quality workmanship, the cabochon surface shows an excellent polish which contributes to a clean, satiny luster and pleasing light reflection from the dome. As a transparent cabochon, the stone transmits light through its body while also revealing internal features, and it has been evaluated as slightly included, evaluated at eye level. The slightly included clarity grade indicates that small inclusions are visible without magnification to an experienced viewer under typical lighting, and these internal characteristics can impart a natural, unique appearance and depth to the gem. The stone has undergone a standard heat treatment enhancement to stabilize and improve its color and overall appearance, a common and accepted practice for sapphires. Heat treatment has been applied carefully to maximize the inherent color while preserving the integrity of the cabochon form, and no other enhancements are reported.

From a practical perspective, this 0.52 carat Montana sapphire is well suited for jewelry applications where a soft, organic aesthetic is desired, including bezel set rings, pendants, or as a complementary center to bespoke designs. The light color intensity and cabochon shape make it particularly suitable for settings where diffuse light and surface luster are preferred over the sparkle of faceting. Considerations for setting include protection of the domed surface through bezel or partial bezel settings to reduce exposure to knocks and abrasion, and routine care should be consistent with standard sapphire handling, including avoiding harsh chemicals and extreme thermal shock. For clients and designers seeking provenance and natural character, this stone provides a tangible link to Montana sapphire sources, and the documentation and presentation by The Natural Sapphire Company support transparent disclosure of weight, dimensions, cut, clarity, enhancement, and origin.
