0.77 Ct. Bluish Green Sapphire from Montana

This 0.77 carat oval bluish green sapphire from Montana exemplifies refined geometry and precise workmanship, with dimensions of 5.57 x 4.82 x 3.65 mm and a mixed brilliant cut that marries scintillation with color depth. The mixed brilliant design places a carefully proportioned brilliant style crown over a modified pavilion geometry, allowing light to enter through the table and crown facets, refract within the core, and return as dynamic flashes of white sparkle and colored fire. The facet junctions are executed to exacting tolerances, producing crisp facet edges and well aligned symmetry, and the excellent polish further maximizes internal reflection, producing lively facet contrast under varied lighting. The result is a gemstone that demonstrates optimal light play for its refractive index, with strong return of light combined with broad areas of saturated bluish green color.

Color and clarity are managed to highlight the sapphire's intense color intensity and transparent body, with a clarity grade of very very slightly included, evaluated at eye level, allowing the stone to maintain both visual purity and natural character. Heat treatment has been applied to stabilize and enhance the blue green hue, a common and accepted enhancement that improves color uniformity without compromising structural integrity. The cutting strategy emphasizes balance between color distribution and brilliance, using elongated oval proportions to enhance face up color while the mixed brilliant facet scheme preserves maximum scintillation. The craftsmanship reflects the standards of The Natural Sapphire Company, with attention to pavilion angle relationships, table size, and crown height tuned to the sapphire's optical properties. This sapphire is ideal for clients seeking a technically sophisticated gem, offering precise faceting geometry that optimizes light performance, intense natural coloration with responsible enhancement, and a clarity profile that reads as clean to the eye while retaining the gemological authenticity of a Montana origin stone.
