1.49 Ct. Bluish Green Sapphire from Montana

This gem is a beautiful transparent 1.49 carat cushion shape bluish green sapphire, measuring 7.10 by 6.00 by 4.41 millimeters, faceted in a mixed brilliant cut with an excellent polish. Evaluated at eye level, the clarity grade is slightly included, which means minor natural inclusions are present but do not significantly interrupt the gem’s overall transparency or sparkle when worn. The color intensity is described as intense, producing a rich bluish green tone that shifts subtly with light and viewing angle, a behavior characteristic of corundum that contributes to visual depth and appeal. This stone has been heat treated, a stable and widely accepted enhancement in the trade that improves color saturation and can reduce the visibility of some inclusions. Origin is Montana, a source known for producing sapphires with unique teal to greenish-blue hues. Taken together, the carat weight, cushion profile, mixed brilliant faceting, and excellent polish deliver an object that is both visually striking and practical for daily wear, with enough presence to be set as a center stone in a bespoke ring or pendant.

From a gemological standpoint this sapphire is classic corundum, hardness nine on the Mohs scale, offering exceptional durability for jewelry destined for regular wear. The mixed brilliant cut blends the scintillation of a brilliant style with the soft outline of a cushion, creating lively flashes from the table and crown facets while preserving the gem’s rich body color. The measured depth of 4.41 millimeters paired with the 7.10 by 6.00 millimeter spread produces well balanced proportions for optimal light return and face up appearance in a cushion silhouette. Slightly included clarity at eye level is a practical characteristic for natural Montana sapphires, and these minor inclusions can act as an internal fingerprint confirming natural origin. Heat treatment is standard practice to stabilize and enhance color, and when performed correctly it is permanent and does not diminish structural integrity. Compared to famous sapphires in history this gem offers a different kind of allure. Kashmir sapphires are renowned for their velvety cornflower blue, and Sri Lankan and Burmese examples often command premiums for vivid pure blues or intense saturation. The Logan Sapphire and other large historic stones illustrate the market’s passion for pure blue tones, but Montana sapphires occupy a special niche for discriminating collectors who prize teal, peacock, and bluish green chroma. Whereas the Star of India and other museum pieces emphasize size and novelty, this Montana cushion offers a refined, wearable character and a color signature that is uncommon among the traditional blue sapphire canon.

For an educated buyer the value proposition of this stone is clear, and The Natural Sapphire Company is pleased to present it with transparency about its qualities and treatment. The intense bluish green color from Montana is relatively rare at this attractive 1.49 carat size, and provenance adds collectible interest because Montana sapphires arise from specific geological conditions that yield distinct trace element chemistry and color range. The excellent polish and mixed brilliant faceting enhance brilliance while preserving the stone’s saturation, making it an excellent choice for a centerpiece in a custom design. Because the stone is heat treated the enhancement is stable and accepted in trade, but we recommend a professional report if you require independent documentation for insurance or resale. Practical care is straightforward, warm soapy water and a soft brush are appropriate, and ultrasonic cleaning is generally acceptable for heat treated sapphires without fractures, though we advise inspection before subjecting any gem to aggressive cleaning. If you are seeking a sapphire that combines the durability and status of corundum with a unique bluish green personality distinct from the classic Kashmir or Sri Lankan blues this Montana cushion represents an intelligent acquisition.
