This transparent aquamarine is a 7.47 carat oval, with precise dimensions of 13.73 by 11.37 by 8.52 millimeters, presented in a mixed brilliant cut. The stone exhibits a medium color intensity in a clear, cool blue, and has been graded slightly included when examined at eye level, indicating minor internal features that do not materially diminish its overall appearance. The cutting and excellent polish have been executed to maximize light return and scintillation, while the mixed brilliant pavilion contributes to a lively play of facets across the table and crown. The gem has undergone standard heat treatment to enhance tone and clarity, a widely accepted and stable enhancement for aquamarine material.
The designation of Tanzania as the origin adds measurable provenance value to this aquamarine, given the countrys growing reputation for producing fine pegmatitic aquamarines with attractive pastel to medium blue hues. Tanzanian deposits often yield stones with clean color and pleasing saturation, characteristics that influence both aesthetic appeal and market perception, and this example aligns with those regional attributes. Provenance from a recognized deposit supports transparent sourcing practices and can provide buyers with additional assurance regarding traceability, geological context, and expected long term stability of the material. In the case of heat treatment, the combination of a reputable origin and standard enhancement practices informs professional assessment and comparability with other market examples.
The Natural Gemstone Company presents this gem with complete specification data to assist in design and valuation. Its substantial carat weight and generous dimensions make it well suited as a primary center stone for a ring or pendant, where the mixed brilliant cut and excellent polish will emphasize brilliance in both daylight and artificial light. Slight inclusions noted at eye level should be considered when setting to optimize durability and appearance, and routine care recommended includes avoiding harsh chemicals and significant thermal shock. For clients seeking documented provenance and a technically described, well cut aquamarine, this Tanzanian stone offers a balanced combination of size, clarity, color, and craftsmanship.
