1.32 Ct. Aquamarine from Nigeria

This 1.32 carat blue aquamarine presents as a transparent trillion shape with precise dimensions of 6.97 x 7.01 x 5.56 millimeters, a profile that balances table proportion and pavilion depth to optimize light return. The trillion cut employed here is a modified triangular brilliant geometry, executed to emphasize scintillation across three apexes and to produce a clean, symmetric facet pattern. Faceting workmanship highlights a well defined crown that disperses light broadly across the table, and a carefully calibrated pavilion that returns light without excessive leakage, resulting in a crisp internal flash and even dispersion. The gem exhibits a faint color intensity, a delicate sea blue that reads closest to classically pale aquamarine tones, and the excellent polish enhances both contrast and luster. Optical properties intrinsic to beryl are evident, the refractive index range providing stable brilliance, and the low birefringence contributing to a single face up behavior that is desirable in precision cuts. Clarity is recorded as very very slightly included when evaluated at eye level, effectively eye clean for practical jewelry use, and the stone is free from any enhancement, indicating that the color and clarity are wholly natural and unaltered.

Provenance and treatment status are central to the specimen value, and this aquamarine originates from Nigeria, a source recognized for producing high quality beryl material with consistent tone. The absence of enhancement, including no heat treatment and no irradiation, preserves the natural crystal chemistry and rarity associated with untreated aquamarine material. From a supply chain and ethical perspective, The Natural Gemstone Company maintains direct procurement relationships with vetted Nigerian sources, implementing chain of custody documentation, origin declarations, and supplier audits to ensure responsible mining practices. Emphasis is placed on minimizing environmental disturbance through selective extraction techniques, and on supporting local mining communities by encouraging fair remuneration, safer working conditions, and investment in basic infrastructure where possible. For buyers who prioritize traceability, the stone can be accompanied by our internal documentation that details the origin and the treatment status, and we offer guidance on independent third party verification for collectors requiring external certification.

For the conscious consumer seeking both technical excellence and ethical assurance, this untreated 1.32 carat trillion aquamarine is well suited to a considered collection. Its compact yet substantial dimensions and the triangular brilliant faceting make it adaptable to a range of settings, from a low profile bezel that protects the apexes while preserving table brilliance, to a three prong solitaire that emphasizes the triangular silhouette and maximizes light exposure. The stone’s hardness and toughness characteristic of beryl provide everyday wearability with standard precautions against sharp knocks, and routine care involves gentle cleaning with warm soapy water and a soft brush, avoiding steam cleaners or harsh chemicals which can compromise mounting integrity. Because the gem is unenhanced, its long term stability under normal wear conditions is dependable, and its natural faint blue hue will age consistently without alteration. We can provide bespoke mounting recommendations from experienced gem setters who understand the mechanical and optical nuances of trillion faceted stones, and we can arrange viewing under standardized lighting conditions to evaluate the interplay of cut, color, and clarity before final selection. Collectors and jewelers who prioritize material integrity, precise craftsmanship, and responsible sourcing will find this Nigerian aquamarine a technically satisfying and ethically aligned addition to their portfolio.
