0.43 Ct. Bi Color Sapphire from Montana

This pear shape bi color sapphire from Montana, presented by The Natural Sapphire Company, is a transparent 0.43 carat gem with dimensions of 6.06 by 4.20 by 2.30 millimeters, finished in a mixed brilliant cut and an excellent polish. The clarity is graded as very very slightly included, evaluated at eye level, which means the stone presents as eye clean to most observers while still retaining natural character under magnification. The medium intense color intensity displays a pleasing bi color separation that ranges from warm amber to soft violet depending on orientation and lighting. Heat treatment has been applied, a standard and stable enhancement for sapphires, used to optimize color and clarity without compromising the inherent material integrity, making this a sound selection for collectors and connoisseurs who expect permanence and market acceptance.

The geometric faceting of this mixed brilliant pear is designed to maximize light play, combining a brilliant crown with precisely angled kite and triangular facets, and a faceted pavilion that promotes efficient internal reflection and scintillation. This faceting strategy produces lively fire and crisp flashes across the bi color zones, allowing each hue to activate under movement and light. For an educated buyer, the value of this sapphire derives from its balanced proportions, high polish, and Montana origin, a provenance known for producing some of the most desirable, characterful sapphires with subtle color phenomena. At 0.43 carat the stone is compact yet strong in presence, ideal for refined solitaire settings, asymmetric designs that showcase the bi color effect, or as a complement in bespoke pieces where orientation and mounting will accentuate the two tone appeal. Given the clarity, cut quality, and stable heat enhancement, this Montana sapphire represents a thoughtful purchase for those seeking a collectible natural gem with excellent lapidary execution and lively optical performance.
