0.32 Ct. Bi Color Sapphire from Montana

This 0.32 carat round bi color sapphire presents a compact yet technically refined profile, measuring 4.08 by 4.07 by 2.66 millimeters. The gem is cut as a mixed brilliant, with a brilliant style crown paired to a modified pavilion, a choice that directs return light through the table while preserving saturation from the lower facets. Faceting geometry has been executed to balance brilliance and color, with careful table and crown relationships that minimize windowing and enhance scintillation. The transparency is excellent, and the clarity grade is very slightly included as evaluated at eye level, indicating only minor natural inclusions that do not detract from face up performance. Medium color intensity yields a nuanced bi color presentation, shifting between deeper teal blue and a softer green depending on viewing angle, an effect driven by pleochroism in corundum and accentuated by precise cutting. Surface finish is excellent, the polish executed to remove facet abrasion and to promote crisp facet junctions, and the gem has been heat treated in a controlled fashion to stabilize and slightly deepen tone while preserving the stone character typical of Montana origin material.

In the context of historic and famous sapphires, this Montana bi color stone does not seek to rival the monumental size of pieces such as the Star of India or the broad, velvety saturation of the Logan Sapphire, rather it evokes aspects of those icons at a technical level. Where the Logan Sapphire is known for its pure saturated blue, and the Star of India for dramatic asterism, this example offers a rare combination of dichroic color and optimized mixed brilliant faceting in a small, wearable round format. The result is a gem that demonstrates how cutting strategy and subtle heat enhancement can create a dynamic visual performance comparable to the finest lapidary traditions, while remaining distinctly Montana in its green blue character. For collectors and designers seeking a gem with technical pedigree and the ability to perform under direct and diffused lighting, The Natural Sapphire Company presents this stone as an exceptional choice, ideal for a finely proportioned ring or pendant where orientation and setting will showcase the bi color shift and the meticulous craftsmanship apparent in the cut and polish.
