2.15 Ct. Blue Sapphire from Madagascar

This 2.15 carat oval blue sapphire represents a refined example of gemological quality that will elevate a discerning collection. The stone measures 7.90 by 7.25 by 4.90 millimeters, and it presents as transparent with an intense color intensity that commands attention without appearing oversaturated. Originating from Madagascar, this specimen exhibits the characteristic depth of tone and evenness of hue that collectors and connoisseurs seek. Enhancement is declared, this sapphire is heat treated to stabilize and enrich the blue, and clarity grade is very very slightly included evaluated at eye level, a level of clarity that yields an eye clean appearance while retaining natural internal structure under magnification. The Natural Sapphire Company presents this piece as a rare balance of weight, proportions, and overall gemological integrity, suitable for display or as the center of a bespoke high end commission.

Cut and faceting are central to the performance of this sapphire, and the mixed brilliant cut applied to this oval has been executed to optimize both brilliance and color. The mixed brilliant approach combines a brilliant style crown with a modified pavilion faceting plan, producing a series of kite and triangular crown facets that direct light into a faceted pavilion structure designed to return and scatter light effectively. Facet junctions are crisp and meet with controlled symmetry, and the excellent polish enhances facet contrast and minimizes light leakage. The oval outline created by the 7.90 by 7.25 millimeter dimensions produces a length to width ratio of approximately 1.09, which is within the preferred range for a balanced oval silhouette, preserving both face up presence and the classic oval elegance favored by collectors who appreciate symmetry and functional beauty.

Color behavior in this sapphire is notable for its intense saturation and balanced tone, yielding a rich medium to deep blue that reads consistently in both direct and diffused lighting. Madagascar sapphires often exhibit nuanced secondary tones and subtle pleochroic shifts, and this stone shows controlled variation when examined from different crystallographic orientations, revealing slightly varying blue nuances without distracting zoning. The heat treatment applied is a standard and stable enhancement that improves both color uniformity and apparent clarity, while remaining a well documented and accepted practice within the trade. The clarity grade very very slightly included evaluated at eye level indicates inclusions are minimal or absent to the unaided eye, meaning the stone delivers a clean visual field that maximizes its color and light return, while under magnification internal features may be observable consistent with natural origin.

From a craftsmanship perspective the polish is excellent, and that finishing quality is immediately evident in the stone’s crisp reflections and lively scintillation. The mixed brilliant faceting has been proportioned to avoid windowing through the table, and to support a lively play of light across the crown and pavilion surfaces. Pavilion depth and crown height have been balanced to produce a controlled return of light rather than a dark or dead center, and the overall execution emphasizes optical performance over merely maximizing weight. For collectors focused on technical details, the way the pavilion facets interact with the crown kite facets produces small, bright flashes of white light interspersed with deeper blue flashes, a combination that reads as both brilliance and color saturation when viewed table up. The excellent polish ensures facet planes are smooth and reflective, contributing to the perceived depth and luster that define high end specimens.

In terms of practical integration into a high end collection or a bespoke jewelry project this sapphire is exceptionally versatile. Its 2.15 carat weight and oval outline make it an ideal candidate for a center stone in a ring, a pendant, or a classic three stone composition paired with white diamonds to emphasize the blue saturation. Consideration of setting type will influence perceived color and brilliance, and a well calibrated prong setting or a low bezel that allows light ingress to the pavilion will highlight the mixed brilliant cut performance. For everyday wear the sapphire benefits from corundum hardness, ranked nine on the Mohs scale, providing excellent resistance to abrasion. The Natural Sapphire Company documents the stone as heat treated and provides provenance from Madagascar, supporting collector confidence in both origin and enhancement. For the collector who values technical attributes and artisanal finishing, this sapphire represents an optimal synthesis of color, cut, clarity, and polish, making it a discerning acquisition that integrates seamlessly into a high end gemstone portfolio.
