1.32 Ct. Bluish Green Sapphire from Montana

This transparent 1.32 carat round bluish green sapphire presents precise proportions and collectible appeal, measuring 6.53 x 6.56 x 4.31 millimeters. Cut to a mixed brilliant style, the gem combines a faceted crown with a pavillion designed to maximize return of light while preserving weight, producing a balanced interplay of brilliance and depth. The color reads as bluish green with medium intense saturation, giving the stone a notable presence without overwhelming darkness. Clarity is graded as very slightly included when evaluated at eye level, indicating only minor internal characteristics that do not detract from overall transparency or visual performance. The polish is excellent, resulting in crisp facet junctions and lively surface reflection.

This sapphire has been heat treated, a stable and commonly accepted enhancement that refines tone and clarity while remaining durable under normal wear conditions. Originating from Montana, the gem carries the geological signature of North American corundum, offering a different character from classic Asian and Australian sources. The combination of Montana provenance, mixed brilliant cutting, and the bluish green hue provides a distinct offering for a discerning collection, particularly for those who prioritize provenance and natural variation in color. The gem’s dimensions and round outline make it versatile for classic solitaire settings as well as modern halo or bezel treatments, allowing curators and jewelers to showcase its color and light performance in multiple design approaches.

As a high-quality natural corundum, this sapphire benefits from inherent hardness and resistance to abrasion, supporting long-term use in wearable pieces while also meeting the expectations of serious collectors. The measured weight, exact dimensions, color intensity, clarity grading, and finishing details make this stone a precise, well-documented addition to a specialized cabinet or bespoke jewelry commission. For those assembling a high-end gemstone collection or sourcing a distinctive center stone, this Montana bluish green sapphire combines documented specifications and attractive visual character, and it is offered through The Natural Sapphire Company.
