0.28 Ct. Bluish Green Sapphire from Montana

At The Natural Sapphire Company we present a transparent 0.28 carat oval bluish green sapphire, offering discerning buyers a compact yet characterful stone that combines classic cut quality with a distinctive Montana hue. The gem measures 5.06 x 3.08 x 2.30 millimeters, and is fashioned in an oval mixed brilliant cut designed to balance sparkle and color saturation. Clarity is graded as very very slightly included when evaluated at eye level, meaning that the stone appears clean to the unaided eye with only minute inclusions that do not detract from the overall visual appeal. Color intensity is medium, producing a pleasing bluish green that shifts subtly with viewing angle, and the polish is excellent, allowing the facets to return light efficiently and enhance brilliance. This sapphire has been heat treated, a common and stable enhancement that improves tone and hue while preserving the natural origin and structural integrity of the crystal. Origin is Montana, a source prized for its range of teal and greenish blue sapphires that often display a unique balance of blue and green tones and a more earthy, natural aesthetic compared with certain classic Ceylon or Kashmir examples.

The internal inclusions visible within this stone serve as unique identifiers that add to its character and provenance, and they should be understood as natural fingerprints of the sapphire formation process. Inclusions in this sapphire are fine and well dispersed, and while they are observable under magnification, they remain very minor at eye level, consistent with the very very slightly included grade. These natural features provide a useful reference for identification and for long term record keeping, and they can also be informative about the gemological environment in which the crystal grew, supporting the Montana origin attribution. Heat treatment may subtly affect the appearance of certain inclusions while enhancing color, and full disclosure of this enhancement is provided to maintain transparency for informed buyers. For an educated purchaser, the combination of documented origin, honest treatment disclosure, precise measurements, excellent polish, and a conservative clarity grade makes this sapphire a trustworthy and attractive choice for a refined custom setting. Consider a low profile or halo mounting to showcase the stone, and care for it with warm soapy water and a soft brush, avoiding harsh chemicals and sudden thermal shocks.
