1.47 Ct. Greenish Blue Sapphire from Montana

This transparent 1.47 carat round greenish blue sapphire measures 6.65 x 6.65 x 4.44 mm, and it is fashioned in a mixed brilliant cut designed to balance strong light return with optimal color presentation. The mixed brilliant design marries a brilliant pavilion with a modified crown geometry to concentrate scintillation while maintaining face up color, and the proportions yield an approximate depth ratio of 66.8 percent, a range that preserves both brilliance and saturation for round sapphires. Clarity is graded as very slightly included, evaluated at eye level, indicating that the stone presents as clean to unaided view with only minor, well distributed internal features visible under magnification, and the excellent polish enhances facet crispness and contrast so that facet junctions remain sharp and scintillation crisp.

The sapphire exhibits medium color intensity in a distinct greenish blue hue characteristic of high quality Montana material, and it has been heat treated, a stable and well established enhancement that refines color tone and reduces the visibility of internal features without compromising the structural integrity of corundum. Heat treatment is fully disclosed, and documented handling ensures predictable optical results, preserving the stone for long term wear. The Montana origin contributes measurable value beyond the physical metrics, because sapphires from this region are prized for their uncommon teal to greenish blue range, a geologic fingerprint that collectors and connoisseurs recognize. Provenance from Montana denotes limited supply, historical desirability, and a distinct trace element profile that often produces clean, cool tones with appealing subtlety, factors that increase desirability in specialist markets.

At The Natural Sapphire Company we emphasize provenance, precision cutting, and full disclosure, and this sapphire exemplifies those commitments, offering a nuanced color profile, superior polish, and robust proportions suitable for fine jewelry. As corundum this sapphire carries excellent wearability for rings or pendants, and the mixed brilliant cutting strategy ensures lively scintillation in motion while maintaining an even color face up. For buyers who prioritize technical quality and documented origin, this Montana greenish blue sapphire represents a refined balance of optical performance and collectable provenance, and our team is available to provide detailed imagery, certification options, and bespoke setting recommendations to showcase the stone to best advantage.
