2.18 Ct. Bluish Green Sapphire from Montana

This transparent cushion shape bluish green sapphire weighs 2.18 carats and measures 8.15 x 6.43 x 4.67 mm, offering a balanced face up presentation and an overall depth of approximately 64.1 percent. The gem is cut in a mixed brilliant style, combining a well proportioned brilliant faceted crown with a carefully faceted pavilion, and it carries a clarity grade of very very slightly included, evaluated at eye level. The color is medium in intensity with a distinct bluish green hue, the polish is excellent, and there has been no enhancement, confirming a natural state consistent with its Montana origin.

The mixed brilliant cut has been executed to optimize the sapphire’s inherent optical qualities, producing an interplay of scintillation and internal depth. Broad, well aligned crown facets act as windows that catch and refract light into the stone, while the pavilion facet structure returns that light through multiple internal reflections, creating lively flashes and consistent return to the eye. The cushion outline with softened corners increases the apparent surface area, allowing more of the stone’s hue to read at typical viewing distances, while the moderate depth prevents color from becoming overly intense or murky. Because the sapphire is transparent and carries very very slight inclusions, the cut’s facet junctions and symmetry become the dominant factors in light performance, permitting crisp flashes without obstruction.

Polish quality and the absence of treatment further amplify the effect of the mixed brilliant design. An excellent polish minimizes surface scattering, so light enters cleanly and exits with distinct brilliance and fire. The cutter’s decision to orient the pavilion and crown proportions to the stone’s pleochroic tendencies yields a balanced presentation of bluish and green tones from different viewing angles, providing subtle color shifts rather than abrupt zoning. Offered by The Natural Sapphire Company, this untreated Montana sapphire combines measured proportions, high quality finish, and a mixed brilliant cushion cut to showcase both lively sparkle and natural color depth, making it suitable for settings that emphasize both brilliance and the unique hue characteristic of Montana sapphires.
