2.19 Ct. Green Sapphire from Australia

This green sapphire is a 2.19 carat transparent asscher cut, octagon shaped gem with dimensions of 7.00 x 6.97 x 4.91 mm. The asscher faceting style is executed with classical step cut geometry, featuring a broad square table, truncated corners, and a concentric series of parallel crown and pavilion facets that create a hall of mirrors effect. Clarity is graded as eye clean at standard viewing distance, indicating the absence of inclusions visible to the unaided eye and allowing the step facets to present uninterrupted planes of color. Color is classified with intense color intensity, exhibiting a deep, saturated green that reads consistently through the table and pavilion, and polish is graded excellent, with facet junctions rendered sharply and facet planes demonstrating minimal polish lines. The stone has been heat treated, a common and stable enhancement for corundum that improves tone and saturation while maintaining the material integrity of the sapphire. The gem is sourced from Australia, a provenance that aligns with known deposits producing richly saturated green material, and the cut proportions are controlled to retain weight while optimizing face up presence.

From a lapidary and setting perspective the asscher cut emphasizes color and clarity rather than the high dispersion brilliance of brilliant cuts, therefore the large table and step facets allow a jeweler to showcase the intense green in designs that favor broad face up exposure. The proportions indicated by the 4.91 mm depth produce a pavilion angle and depth that balance light return with retention of carat weight, reducing windowing while avoiding excessive depth that can darken the face up appearance. The faceting geometry produces well defined pavilion facets that reflect color back through the crown, and precise symmetry is evident in the octagonal outline which aids in even light distribution and predictable reflections when set. The girdle should be assessed at mounting to confirm thickness uniformity, as a moderately faceted or polished girdle will facilitate secure prong engagement without risking chip exposure at the corners. The truncated corners characteristic of asscher and octagon shapes call for careful corner protection, whether by four or eight prong arrangements or by a custom bezel that follows the octagonal silhouette, and the excellent polish minimizes surface diffusion that can otherwise soften facet contrast under high magnification.

For customization into jewelry the stone adapts to a wide variety of settings with specific technical considerations. As a solitaire in a classic four prong mounting, using corner prongs that align with the truncated corners preserves the octagonal geometry and provides maximum table visibility. A bezel setting offers superior protection for daily wear, and for this asscher cut a thin octagon shaped bezel that matches the crown outline maintains the visual proportions while increasing retention security, particularly useful in rings or men s pieces. Halo settings can be designed to enhance perceived size and color contrast, using melee diamonds with calibrated spacing to follow the step cut edges, or alternatively colored sapphires can be used as a contrast halo to emphasize green saturation. For tension and east west orientation designs the pavilion depth and girdle profile must be verified to ensure clamping forces distribute evenly, and for three stone compositions the asscher works well as a center with tapered baguette or kite shaped side stones that echo step facets. For earrings and pendants the uniformity of the cut and the eye clean clarity allow for open back settings to maximize light entry, and a cathedral or bezel cup can be engineered to control light leakage for a deeper, richer face up tone. Metal choices such as platinum or 18 karat yellow or rose gold will alter perceived warmth and contrast, with white metals promoting cooler presentation and yellow or rose metals intensifying warm undertones in the green. When commissioning a bespoke mount from The Natural Sapphire Company, technical specifications such as exact girdle profile, location of the culet relative to center, and recommended prong seat depths will be provided to ensure precise fabrication, and recommendations on protective design elements will be tailored to the intended wear scenario, whether daily, occasional, or heirloom use.
