1.57 Ct. Bluish Green Sapphire from Montana

This 1.57 carat oval bluish green sapphire presents a finely considered combination of proportions and faceting, dimensions 7.33 by 5.92 by 4.39 millimeters, length to width ratio approximately 1.24, and overall depth approximately 66 percent. The mixed brilliant cut employs a brilliant style crown paired with a modified step pavilion, a configuration chosen to balance lively face up brilliance with controlled color saturation. The table and crown facets have been proportioned to promote contrast and scintillation, while the pavilion facets are aligned to optimize internal reflection, producing crisp facet junctions and a pleasing window free presentation. Clarity registers as very slightly included at eye level, with inclusions that are minimal and do not detract from transparency or polish, and the finish is described as excellent, indicating meticulous lapidary work and well executed facet symmetry. Color is medium intensity bluish green, presenting a cool teel tone that is evenly distributed across the table, and the stone is completely transparent with no enhancement, an attribute that preserves natural optical characteristics and simplifies color consistency in settings.

The Montana origin of this sapphire contributes significantly to its desirability and market value, Montana sapphires are renowned for their distinctive blue to green palette and for producing material that is frequently left untreated, a trait highly prized by discerning collectors and connoisseurs. Geological formation in alluvial and volcaniclastic environments in Montana yields trace element profiles that favor greenish blue hues and often result in excellent clarity, making stones from this source both visually appealing and historically significant. For buyers who prioritize provenance, the origin provides a narrative of rugged American deposits and reliable color typicity, enhancing collectability and resale potential. At The Natural Sapphire Company we emphasize origin as a key component of value, and this untreated Montana sapphire exemplifies the intersection of skilled cutting, natural color, and documented source, making it particularly appropriate for elegant solitaire settings or bespoke jewelry where the stone’s technical merits and provenance can be appreciated.
