1.11 Ct. Bluish Grey Sapphire from Montana

This 1.11 carat marquise sapphire from The Natural Sapphire Company presents a technically refined package for the specialist buyer, transparent and precisely faceted to maximize optical performance. The stone measures 9.26 by 5.28 by 3.50 mm, yielding a length to width ratio of approximately 1.75, a proportion that preserves classic marquise silhouette while avoiding excessive bowing or narrowness. The cutting style is faceted, executed as a mixed brilliant cut, with a brilliant oriented crown and a pavilion facet architecture designed to return light efficiently, producing focused scintillation and balanced flash across the girdle. Clarity is graded very very slightly included, evaluated at eye level, which in practice means minimal internal features that do not impede visual transparency or sparkle. Color registers as bluish grey with intense color intensity, and the polish is excellent, indicating tight facet junctions and smooth facet planes that enhance luster. The gem has been heat treated, a stable and well established enhancement for sapphire that optimizes hue and clarity without compromising structural integrity. The reported Montana origin contributes to the gemological profile, reflecting a regional trace element signature that favors teal and slate blue tones rather than the saturated cornflower blues of other deposits.

Rarity in both size and color is a defining attribute of this example, making it notable among comparable stones on the market. Marquise sapphires above one carat from Montana, with a bluish grey saturation at intense level, are uncommon, because most rough yields in this color range are smaller or require more aggressive cutting to achieve uniform tone. The combination of a desirable 1.11 carat weight, a well proportioned marquise outline, mixed brilliant faceting to balance brilliance and color, and a very very slightly included clarity grade places this sapphire in a scarce category of stones suitable for high quality bespoke jewelry. For the technically minded buyer considering setting decisions, the stone will perform well as a solitaire center where the length enhances finger coverage, or as a precision matched component in three stone or cluster designs where its consistent hue and excellent polish will harmonize with complementary side stones. The Natural Sapphire Company presents this gem for clients who prioritize measured proportions, documented origin, and the technical craftsmanship that elevates rare color and size into wearable refinement.
