2.86 Ct. Bluish Green Sapphire from Montana

Presented here is a transparent 2.86 carat cushion shape bluish green sapphire, with precise dimensions of 8.09 x 7.11 x 5.20 millimeters, sourced from Montana. The face up color reads as a compelling bluish green, sitting between teal and deep sage, and the intensity of the color is described as intense, which means the saturation is strong while still allowing for lively reflections. This stone has a mixed brilliant cut that combines the scintillating performance of brilliant facets with the color preserving geometry of larger pavilion facets, and the excellent polish contributes to sharp facet junctions and bright reflections. The clarity is graded very slightly included, evaluated at eye level, which indicates that any inclusions are minimal and do not detract from the gem when it is set or worn. The gem is transparent, and its optical behavior includes a pleasing balance of sparkle and depth, attributes that are enhanced by Montana provenance, a locality known for producing sapphires with unique teal and bluish green character. The presence of very slight inclusions can be seen by the knowledgeable eye as confirmation of natural origin, and when combined with thoughtful cutting and finishing, they have negligible effect on the stone’s overall visual impact.

From a technical and gemological perspective this sapphire presents advantages that matter to an educated buyer. The average diameter of the stone is approximately seven point six millimeters, and with a depth of five point two millimeters the resulting depth is approximately sixty eight percent, a proportion that supports both strong light return and preservation of the intense color common to sapphires of this hue. The mixed brilliant facet arrangement was chosen to maximize scintillation on movement while keeping a stable and saturated body color in face on viewing. The clarity description very slightly included, evaluated at eye level, typically indicates small natural crystals or needles that do not compromise toughness, and are often used by gemologists to help verify natural origin. Enhancement by heat treatment is noted, and this is an industry standard treatment that improves color uniformity and reduces the visibility of certain inclusions through diffusion of color and relief of strain, it does not involve polymer filling and it is stable under normal wear and standard jewelry fabrication processes. The excellent polish and proportion choices made by the lapidary ensure optimal facet alignment, which enhances both brilliance and the perception of color intensity, and these finishing qualities also reduce the likelihood of chipping during setting when proper care is taken.

For custom jewelry the cushion shape and the specific size of this 2.86 carat stone make it exceptionally versatile and desirable as a centerpiece. The cushion outline gives a timeless silhouette that adapts equally well to classic four prong mounts and to more protective settings such as full bezels or hybrid bezel and prong designs, and its dimensions are large enough to make a striking engagement ring, pendant, or cocktail ring while remaining comfortable for everyday wear. Designers will appreciate that the mixed brilliant cut creates lively flashes that are complemented by small accent diamonds or colored stones, allowing for halo or split shank treatments that enhance perceived size and add contrast without overwhelming the sapphire’s intense color. Metal choice will influence how the bluish green reads, yellow gold will warm the green tones, rose gold will soften the overall appearance, and white gold or platinum will emphasize the bluer notes and increase perceived brilliance. Practical considerations include selecting a mounting that protects the pavilion and girdle, using slightly deeper seatings to avoid stress during stone setting, and choosing prong profiles that secure the cushion corners, typically four or six rounded prongs for balance and protection. For the discerning buyer provenance from Montana adds collectible interest and geological specificity, and because The Natural Sapphire Company documents origin and treatment we provide transparent information and design consultation to ensure the final piece showcases the gem’s strengths, maintains its integrity, and meets the expectations of an educated purchaser.
