1.18 Ct. Bluish Green Sapphire from Montana

This transparent 1.18 carat trillion shape sapphire offers an exceptional combination of size, cut and color that will appeal to an educated buyer. At 1.18 carats this stone crosses a psychologically important threshold where per carat value typically increases, making it measurably more rare and valuable than stones just below the one carat mark. The measured dimensions of 6.59 x 6.82 x 3.96 mm yield a pleasing spread for a trillion cut, and the faceted cutting style has been executed to produce strong light return and scintillation despite the stone s dark color intensity. The eye clean clarity, assessed at normal viewing distance, means the gem presents a clean window with no visible inclusions to distract from its bluish green hue, which is uncommon and sought after for its distinctiveness. Excellent polish contributes to crisp facet junctions and optimal brilliance, and the overall proportions indicate a cutter focused on maximizing both weight retention and optical performance.

As a Montana origin sapphire, this gem carries provenance that many collectors and connoisseurs value, Montana sapphires are known for their unique and often complex blue to green tones, and this specimen s bluish green character is representative of that locale. The sapphire has been heat treated, a widely accepted enhancement that stabilizes color and clarity while remaining permanent under normal wear, and it is disclosed here to allow buyers to make an informed evaluation of value. For those evaluating value, the 1.18 carat weight is a primary driver, both because it places the stone into a higher value tier and because larger natural Montana sapphires with eye clean clarity and strong color intensity are relatively scarce. This makes the stone attractive for a bespoke engagement ring center, a striking pendant, or a collector s cabinet where provenance and natural character matter. The Natural Sapphire Company stands behind transparent disclosure of origin, treatment and grading details, and this sapphire exemplifies the balance of rarity, aesthetic appeal and reliable gemological attributes that knowledgeable buyers seek.
