0.27 Ct. Bluish Green Sapphire from Montana

This 0.27 carat oval bluish green sapphire from Montana is a compact example of measured craftsmanship and material character, presented by The Natural Sapphire Company. The stone measures 4.98 x 3.04 x 2.22 mm, and the lapidary has executed a mixed brilliant cut to balance scintillation with face up color. Clarity is graded as very slightly included when evaluated at eye level, indicating minor crystal and needle type inclusions that do not interrupt the stone in typical mounting orientations, and polish is excellent which enhances facet definition and optical return. Enhancement is heat treated, a standard and stable procedure for altering tone and saturation in sapphires, and the piece is transparent with medium color intensity suitable for a refined, wearable center stone or an elegant accent in a bespoke setting.

The cut deserves careful attention for buyers who prioritize optical performance, because the mixed brilliant approach combines a brilliant style crown with a pavilion that retains modified facets to manage weight distribution and color concentration. The length to width ratio is approximately 1.64, giving a gently elongated oval silhouette that sits well on finger and pendant designs while maintaining a pleasing symmetry. The overall depth, when expressed relative to the average of the length and width, is approximately 55 percent, a proportion that yields a slightly deeper pavilion and contributes to the perceived depth of color under face up viewing. The table and crown facet arrangement have been optimized to produce lively scintillation on movement, while the mixed pavilion contributes to localized areas of light return that can accentuate the bluish green hue, therefore the cutter has traded off maximum spread for stronger color and distinctive light play.

Chromatic characteristics are central to this sapphire, the dominant hue being a balanced bluish green with medium intensity, which positions the stone within a spectrum that reads as cool and slightly aquatic under daylight, while it can lean toward greener or bluer tones depending on environmental lighting and viewing angle. Montana sapphires are known for their particular trace element signatures and crystal growth conditions, which often yield nuanced, complex hues rather than a single saturated primary color, and this specimen exemplifies that regional signature with a subtle interplay of blue and green components. Pleochroic behavior can be expected in natural corundum, and in practice this stone will show slight variation in hue if rotated under different light sources, which experienced gem buyers value as a sign of natural crystallography and material authenticity.

Provenance from Montana increases the collectible and aesthetic value of the sapphire in several technical and market relevant ways, because American origin sapphires are relatively uncommon in the global supply and they carry a documented geological story that many connoisseurs and designers find desirable. Montana deposits yield material that is characteristically cool in tone and frequently displays fine transparency with moderate saturation, traits that are sought after for their versatility in both classic and contemporary jewelry styles, and when combined with a carefully executed mixed brilliant cut and excellent polish the result is a stone that performs well under loupe and to the naked eye. At The Natural Sapphire Company we emphasize origin documentation and traceability as part of our service, because provenance informs grading context, pricing, and long term desirability, and because it enables clients to make informed decisions about treatments and expected performance. This sapphire, with its modest carat weight but noteworthy color and finish, is particularly suitable for refined engagement rings, solitary pendants, or as a matched component in a custom design, and our team can advise on mounting strategies that protect the deeper pavilion and accentuate the oval outline while preserving the material integrity that defines Montana sapphires.
