0.90 Ct. Bluish Green Sapphire from Montana

This transparent bluish green sapphire weighs 0.90 carat and is cut into a refined oval shape, with exact dimensions of 6.06 x 5.16 x 3.78 mm. The mixed brilliant cut combines precision faceting with an eye for balance, producing a lively interplay of scintillation and color. Clarity is graded as very very slightly included evaluated at eye level, a level of purity that is uncommon in sapphires of this tone and size. Color intensity is described as intense, and the surface finish is an excellent polish, both of which underscore the gem quality. The sapphire is heat treated, a standard and stable enhancement that optimizes color and clarity without obscuring the stone's natural character. The material originates from Montana, a source known for producing a distinctive range of blue and green sapphires, and this particular piece represents a noteworthy example from that region.

What sets this stone apart is its combined rarity in both size and color when compared to similar sapphires on the market. Sapphires under one carat frequently exhibit paler tones or more pronounced inclusions, while richly saturated bluish green material at this weight is less common. The oval outline and mixed brilliant cut maximize face up appearance, so the 6.06 x 5.16 mm table presents strongly for its 0.90 carat weight, creating a visual impact that belies the sub one carat measurement. The intense bluish green hue occupies an uncommon niche between classic blue and distinctly green sapphires, offering a level of saturation and purity that is often reserved for larger stones or those from different localities. The very very slightly included clarity at eye level further elevates the rarity profile, as most comparable gems with such vivid color will show more noticeable internal characteristics when examined without magnification. The excellent polish and precise facet junctions enhance light return, which accentuates both fire and body color, reinforcing the gem's presence in any setting.

From a practical and design perspective, this Montana sapphire is versatile and well suited to a range of applications in fine jewelry. Its size and shape accommodate classic solitaire mounts, elegant halo designs, and contemporary three stone layouts, while the strong color can be paired with metals that either contrast or complement, such as white gold or platinum for a cooler presentation or yellow gold for a warmer emphasis. The mixed brilliant cut encourages lively performance under varied lighting situations, making it appropriate for daily wear items like engagement rings as well as for dress or statement pieces. Because the enhancement is a stable heat treatment, normal jewelry care practices are appropriate, and professional inspection and cleaning are recommended to preserve polish and setting security. Provenance from Montana adds a layer of interest for collectors and connoisseurs who value geographic identity in their gemstones.

The Natural Sapphire Company presents this sapphire with detailed documentation of the described attributes and a commitment to transparency about treatment and origin. For buyers seeking a gemstone that is notable for its uncommon conflation of intense bluish green color, excellent clarity at eye level, and a face up presence that exceeds expectations for a 0.90 carat oval, this stone stands as a distinctive option. Its combination of optical performance, precise cutting, and geological provenance means it occupies a rare position among sapphires in this size range, offering both immediate aesthetic appeal and enduring desirability for bespoke and heirloom jewelry.
