AI Appraisal Estimate

This specimen is a natural gemstone of the Beryl species, specifically the Aquamarine variety, weighing 2.99 carats. It features a professional emerald step-cut with dimensions measuring approximately 11.0mm x 7.5mm x 4.8mm. The gemstone exhibits a cool, light blue hue that is characteristic of top-tier aquamarine, though its transparency is notably hindered by internal characteristics. The physical structure shows heavy internal inclusions, specifically long, parallel tube-like growth or 'rain' inclusions and significant feathery veining throughout the table facet, which significantly affects light return and clarity. The cut craftsmanship appears symmetrical with clean facet edges, though the overall luster is impacted by the density of internal fissures. As per standard industry practices, this stone is identified as commonly heat-treated to enhance its blue saturation. Despite the inclusions, it remains a genuine earth-mined beryl suitable for custom jewelry settings or collectors of included gemstone specimens.

Based on my examination of the provided specifications for this 2.99-carat Emerald-Cut Natural Aquamarine, I have reached the following valuation. The gemstone is a genuine species of Beryl, confirmed by its physical dimensions (10.91 x 7.50 x 4.83 mm) and characteristic light blue hue. While the 'Emerald Step-Cut' is professionally executed with symmetrical facet edges, the value is significantly constrained by clarity. My visual assessment identifies heavy internal 'rain' inclusions and prominent feathery veining. In the market for Aquamarine, transparency and the absence of eye-visible inclusions are the primary drivers of price; stones of this size with high clarity often command $100-$150 per carat, whereas heavily included specimens like this one typically trade at a deeper discount ($50-$75 per carat). The standard heat treatment noted is common and expected for this variety, thus it neither adds nor detracts significantly from its market position. This piece is best suited for a collector of mineral inclusions or for use in artisan jewelry where a 'sleepy' or organic look is desired over brilliance. Please note that this appraisal is based on digital data and images. Without a physical inspection, I cannot definitively verify the absence of surface-reaching fissures that might affect structural integrity. A full authentication would require a hands-on examination using a refractometer to confirm the refractive index and a polariscope to ensure it is not a synthetic or glass imitation. Professional laboratory certification from GIA or IGI would be necessary to provide a definitive grading of its clarity and origin.
