0.81 Ct. Bluish Green Sapphire from Montana

This transparent 0.81 carat round bluish green sapphire measures 5.37 x 5.32 x 3.70 mm, presenting a near perfectly circular outline with dimensions that yield a mean diameter of approximately 5.345 mm and a depth of approximately 69.3 percent. The gem is fashioned in a mixed brilliant cut with a brilliant crown and a step pavilion, a faceting strategy that balances strong internal light return with controlled color saturation. The mixed pavilion complements the crown facet geometry to produce lively facet-to-facet scintillation and a focused face up color, while the crown geometry opens the table to deliver immediate visual impact. Clarity is graded very slightly included evaluated at eye level, indicating minor natural inclusions that do not detract from the gem when mounted, and that in many lights enhance character by breaking light into subtle pinpoint highlights. Color intensity is intense, with a stable bluish green hue that shows a measurable pleochroic response between blue and green tones as the stone is rotated, a characteristic consistent with Montana provenance. The polish is excellent, with crisp facet junctions and a clean finish that maximizes both luster and precise light performance. Enhancement is by controlled heat treatment, a standard and stable practice that improves color homogeneity and is fully disclosed.

As a gift this sapphire offers technical excellence and emotional resonance, making a striking choice for a milestone or a special celebration. The combination of an intense bluish green hue, robust mixed brilliant faceting, and an eye level clarity that remains engaging yet wearable ensures the stone reads as vivid and substantial once set, particularly in fine prong or bezel settings that allow the crown facets to interact with ambient light. The gem is durable for everyday wear due to the inherent hardness of corundum at Mohs 9, and its Montana origin gives it a distinct mineralogical signature prized by collectors and connoisseurs alike. Presented by The Natural Sapphire Company, this 0.81 carat Montana sapphire comes with provenance and full disclosure, and it makes a memorable and technically sophisticated gift for someone special who appreciates the intersection of precise craftsmanship and natural beauty.
