5.69 Ct. Brownish Green Sapphire from Montana

This 5.69 carat oval brownish green sapphire measures 10.85 x 8.88 x 7.15 mm, exhibiting a precision cut in a faceted mixed brilliant style that balances fire and color saturation. The mixed brilliant paradigm places a brilliant facet structure across the crown to optimize scintillation, paired with a modified pavilion geometry that deepens perceived color without sacrificing light return. Proportions are well calibrated, the oval outline is symmetrical with a consistent girdle, and the depth dimension yields an efficient balance between brilliance and body color. Clarity is graded eye clean at standard viewing distance, indicating no inclusions visible to the unaided eye, and the finish is reported as excellent polish, producing crisp facet junctions and lively facet crispness. Color intensity is intense for this hue, a stable brownish green that presents uniformly across the table under standard illumination, and the stone is natural with no enhancement, originating from Montana, a source noted for distinctive green and teal tones in corundum specimens.

In practical application this sapphire is highly versatile, performing equally well in casual and formal settings due to its combination of robust physical properties and refined cutting. As corundum with inherent surface durability, it is suitable for daily wear in settings such as rings and bracelets when secured by a protective bezel or well executed prong mounting, and it also lends itself to elevated designs including halo or three stone compositions where the intense color will read differently against white or yellow metals. The mixed brilliant cut enables dynamic light play in motion, making this gem an engaging focal point for pendants and masculine pieces like cufflinks, while the eye clean clarity supports open settings that expose the pavilion and crown geometry. The Natural Sapphire Company provides this Montana sapphire as an untreated, well finished example for connoisseurs who value traceable origin, precise cutting technique, and minimal intervention, and we are available to advise on setting choices that will best showcase the oval proportions, intense color, and excellent polish for both everyday elegance and formal presentation.
