1.52 Ct. Bluish Green Sapphire from Madagascar

This 1.52 carat round bluish green sapphire presents precise dimensions of 6.77 by 6.83 by 4.05 millimeters, yielding an average diameter of approximately 6.80 millimeters and an overall depth ratio of approximately fifty nine point six percent. The stone is fashioned in a mixed brilliant cut, a strategy that combines a brilliant faceted crown with a modified pavilion to maximize face up spread while preserving depth for optimal light return. The mixed brilliant execution on this piece results in crisp, well defined facet junctions across the crown, a sufficiently deep pavilion that channels light back through the table, and a girdle that has been controlled to maintain seated stability in typical ring settings. The excellent polish enhances the interplay of small facet reflections and larger flashes, producing a clean visual effect that benefits both brilliance and scintillation in daylight and artificial lighting.

Color is the defining attribute of this sapphire, described as bluish green with medium color intensity, a hue that occupies a rarer position on the sapphire color spectrum when compared to pure blue or vivid green material. The stone shows balanced color distribution with subtle internal color dynamics that shift slightly toward blue in cooler light and toward a more green leaning tone in warmer light, consistent with pleochroic behavior common to corundum. Trace element chemistry consistent with Madagascar origin, notably iron with possible minor titanium contribution, produces the teal leaning character that collectors and connoisseurs seek. At this carat weight and with this specific bluish green tonality, material of natural origin and with no enhancement is uncommon, and the absence of heat or other treatments preserves the stone in its native state.

Clarity has been graded as slightly included when evaluated at eye level, a practical clarity category that indicates the presence of small natural mineral inclusions or silk like features that are visible to a trained viewer but do not dominate the stone or materially compromise structural integrity. These inclusions act as identifying characteristics that confirm natural origin and help to authenticate provenance, while the mixed brilliant facet scheme and excellent polish mitigate any visual impact by breaking up and masking small internal features through controlled light dispersion. The result is a transparent gem that reads clean and lively to the unaided eye, with internal characteristics that will not typically affect daily wear. The corundum hardness of nine on the Mohs scale, together with the measured proportions of this sapphire, makes it well suited to use as a primary center stone in a ring or for bespoke jewelry where long term durability and visual presence are required.

Provenance and treatment status are central to the market value of color center gems, and this sapphire is notable for two converging rarities, size and natural color, as offered by The Natural Sapphire Company. Madagascar is an increasingly important source for teal and bluish green sapphires, but pieces in the one and a half carat range that retain a medium intensity natural bluish green hue and that have not undergone enhancement are scarce in the current market. For clients who prioritize natural provenance and minimal intervention, this sapphire represents a technically superior choice, combining measured proportions, a purposeful mixed brilliant cut, transparency without significant clarity compromise, excellent polish, and documented absence of enhancement. The Natural Sapphire Company can assist with advice on setting profiles that preserve pavilion depth while maximizing face up appearance, and can arrange independent gemological evaluation on request to support confident acquisition and long term collection management.
