0.85 Ct. Orange Sapphire from Montana

This gem is a transparent 0.85 carat oval orange sapphire, precisely measured at 6.82 x 4.62 x 3.24 millimeters, presented in a mixed brilliant cut that balances scintillation and color saturation. The stone exhibits vivid color intensity, an excellent polish, and a clarity grade assessed as very slightly included at eye level. In practical terms the inclusions are minimal and do not distract from the visual experience, so to the unaided eye the gem appears effectively flawless, allowing light to travel through the pavilion and crown with minimal interruption. That near-eye-clean presentation, combined with the vivid orange tone, produces strong face-up brilliance and a lively play of light across the table and facets, enhancing its beauty from every angle whether viewed in motion or at rest.

From a gemological perspective the mixed brilliant cut is an intentional choice to maximize both color display and light return in a small, well-proportioned stone. The oval proportions and measured depth yield an optimal balance between saturation and brightness, enabling the vivid orange to remain lively without appearing dark or windowed. The excellent polish contributes materially to the gem’s visual performance, creating crisp facet junctions that boost brightness and contrast. Clarity described as very slightly included, evaluated at eye level, indicates that microscopic or minor internal features are present but do not compromise structural integrity or the overall appearance when worn. For the educated buyer this combination of transparency, cut, and polish is critical, because it determines how efficiently the sapphire captures, refracts, and returns light to the observer.

Origin and treatment are essential to evaluating both aesthetic and market value, and this sapphire’s Montana provenance is significant. Montana sapphires are prized for their unique palette and for the geological conditions that produce distinctive hues, and when combined with a vivid orange saturation this stone becomes relatively rare compared with more common blue material. The gem has been heat treated, a widely accepted and stable enhancement used to intensify color and improve clarity without affecting durability. Heat treatment in corundum is permanent under normal wearing conditions and is fully discloseable, which is important for long term value and for maintaining transparent provenance. Trace elements such as iron and other transition metals influence the orange coloration, and the combination of origin, vivid saturation, and near-eye-clean clarity makes this piece desirable to collectors and connoisseurs who prioritize both rarity and wearability.

For practical ownership considerations this sapphire benefits from the intrinsic hardness and toughness of corundum, making it well suited to everyday jewelry settings such as rings, pendants, or bespoke pieces where its brilliant orange face-up color can be showcased. Because the stone is nearly eye-clean, a simple, open-setting design will emphasize color and light rather than hiding the pavilion, and bezel or prong settings with low-profile galleries will protect the girdle while permitting maximum light entry. We recommend routine cleaning with warm soapy water and a soft brush for maintenance, and professional inspection when resetting. At The Natural Sapphire Company we prioritize full disclosure on origin and treatment, and we can supply further gemological documentation on request. For the discerning buyer seeking a vivid, ethically sourced Montana orange sapphire with superb cut and polish, this 0.85 carat oval is a striking and technically excellent choice that delivers visual impact and long-term desirability.
