0.70 Ct. Green Sapphire from Madagascar

This green sapphire begins with precise gemological specifications that define its character and practical value. It weighs 0.70 carat, and presents in a transparent, oval shape. Its finished dimensions measure 6.09 by 4.14 by 3.21 millimeters, and it has been fashioned with a mixed brilliant cut that balances faceting to enhance both color and scintillation. The clarity grade is very very slightly included evaluated at eye level, indicating inclusions that are minimal and do not materially affect the gem when viewed without magnification. Color falls into a medium intensity range, a tone that communicates green distinctly while maintaining versatility for a range of settings. The surface finish is of excellent polish, lending a refined luster to each facet plane. The sapphire has been heat treated, a standard enhancement applied to stabilize and improve color distribution, and its origin is Madagascar, a source known for producing sapphires with appealing hues and crystalline clarity. The Natural Sapphire Company documents these attributes for transparency and accurate representation.

The journey from mine to market for this sapphire followed a series of deliberate stages that prioritize provenance, quality control, and craftsmanship. Extraction began at artisanal to small scale operations in Madagascar where rough material was recovered from alluvial gravels and secondary deposits. The rough crystals were then evaluated on site for color, clarity, and potential yield. Pieces with favorable transparency and color saturation were selected for cutting and then transported under documented channels to our cutting partners. The mixed brilliant cut was chosen to maximize optical performance given the stone's natural crystal habit and medium color intensity. Skilled cutters adjusted facet angles to enhance light return while preserving weight and maintaining an even tone across the oval outline. After cutting, the sapphire underwent meticulous polishing to achieve an excellent finish, and a controlled heat treatment process was applied to improve color uniformity. Throughout the process, The Natural Sapphire Company maintained records of origin and treatment, and subjected the finished gem to comprehensive gemological examination including precise measurement, weight verification, and clarity assessment at eye level. Independent and internal assessments confirm the stated attributes, and all disclosures regarding heat treatment and origin accompany the stone.

When presented to the market, this 0.70 carat green sapphire is accompanied by clear documentation of its specifications and treatment history, enabling informed decisions by jewelers and buyers. The mixed brilliant cut and excellent polish produce a balance of brilliance and color depth, making the gem suitable for a variety of settings including solitaire designs and multi stone arrangements, where its oval proportions and medium color intensity contribute to visual harmony. The clarity grade very very slightly included evaluated at eye level denotes that the stone will exhibit clean appearance in typical wear, while collectors and designers will appreciate the natural internal features that confirm authenticity. Heat treatment, as applied here, is stable and enduring under normal conditions, and routine wear with standard care practices will preserve the stone’s appearance. Given its origin in Madagascar, the gem reflects geological conditions that often yield fine crystalline material, and The Natural Sapphire Company provides provenance information as part of our commitment to responsible sourcing and full disclosure. This sapphire exemplifies a well documented and carefully finished gemstone, described here with its precise measurements, cut, clarity, color intensity, polish quality, treatment history, and origin, so that both connoisseurs and craftsmen can evaluate its suitability for their intended use.
