0.45 Ct. Bluish Green Sapphire from Montana

This transparent 0.45 carat oval bluish green sapphire measures 5.00 by 4.05 by 2.81 mm and exhibits a mixed brilliant cut designed to maximize both sparkle and color depth. The cutter has employed a brilliant facet arrangement on the crown combined with a modified step pavilion to preserve weight while directing light back through the table, producing controlled scintillation and strong color saturation. Color intensity is graded intense, yielding rich teal tones that shift subtly with orientation due to pleochroic behavior characteristic of corundum. Clarity is described as very slightly included evaluated at eye level, indicating that inclusions are minor and localized, visible only under close inspection and not compromising windowing or overall visual appeal. The polish is excellent, with crisp facet junctions and a smooth, reflective table that enhance apparent transparency and allow the mixed cut geometry to read cleanly to the eye.

This sapphire has been heat treated, a stable and common enhancement that improves color uniformity and reduces the visibility of minor inclusions without affecting structural integrity. Origin is Montana, noted for producing sapphires with distinctive bluish green to teal hues, and this specimen reflects that regional character. In terms of durability the material is corundum, which rates 9 on the Mohs scale, second only to diamond at 10, significantly harder than topaz at 8 and quartz at 7, which ensures excellent resistance to scratching and suitability for daily wear. Given its oval outline and moderate depth of 2.81 mm, secure mounting is recommended, with four to six prong settings or a bezel providing both security and protection for the girdle and pavilion. The combination of intense color, mixed brilliant faceting, and excellent polish makes this gem particularly well suited to fine jewelry applications where both color saturation and light performance are desired. For customers seeking a distinctive Montana sapphire with technical precision in cutting and consistent durability for everyday use, The Natural Sapphire Company offers this stone as a balanced choice that marries artisanal cutting decisions with gemological quality.
