1.44 Ct. Green Sapphire from Tanzania

This Tanzanian green sapphire is a study in precise gemmological balance, presented at a weight of 1.44 carats with dimensions of 6.69 by 7.50 by 4.07 millimeters. The stone is fashioned into a five sided fancy shape with a modified brilliant facet arrangement, and it displays intense color intensity with an even face up appearance. Clarity has been assessed as very slightly included as evaluated at eye level, and these minute inclusions are confined to non disruptive positions below the crown, preserving the gem's integrity and light return. The material is natural corundum from Tanzania, with no enhancement, which assures both stability and the unaltered character of the green hue, a quality increasingly prized by informed buyers who value provenance and treatment disclosure.

Cutting and finish have been executed to accentuate brilliance and scintillation in a non conventional outline, the brilliant cut facet schema has been adapted to suit the pentagonal symmetry, the crown is optimized with well proportioned star and bezel facets that direct light to the table, and the pavilion is cut to a depth that maximizes internal reflection. The pavilion depth of four point zero seven millimeters yields a depth proportion of approximately fifty seven percent relative to the average of the length and width, which contributes to lively return and a broad face up spread for the given carat weight. The excellent polish is immediately evident at facet junctions and girdle continuity, the crisp facet plane intersections produce sharp light return and minimal light leakage, and the symmetry across the modified brilliant layout maintains consistent flashes when the gem is rotated. From a gemmometric standpoint this sapphire benefits from corundum inherent optical properties, the refractive index of corundum yields strong brilliance, and the modest birefringence characteristic of sapphire can produce subtle pleochroic behavior in green material, so orientation in the mounting can enhance the most desirable bluish green to yellowish green tones depending on the chosen face up direction.

For engagement applications this sapphire is particularly compelling, its hardness at nine on the Mohs scale assures excellent resistance to wear compared with common alternatives, and the absence of heat or diffusion treatment means the color will remain stable over a lifetime of daily wear. The combination of a distinctive fancy shape and a modified brilliant facet pattern creates an engagement center that reads both elegant and technical, appealing to buyers who appreciate exacting craftsmanship and measurable performance. Practical setting considerations include a secure prong or low bezel that follows the pentagonal outline to protect the five points, while allowing sufficient exposure of the crown to optimize brilliance. Because the gem displays intense saturation rather than extreme darkness, the stone photographs and presents well in both white and warm metals, and the orientation of the pavilion relative to the table can be selected to emphasize either the greener axis or the bluer axis inherent in pleochroic samples.
