1.65 Ct. Aquamarine from Nigeria

There is a long and evocative lineage behind each aquamarine, a gemstone that carries the color and calm of the sea into the language of jewelry and legacy. For centuries aquamarine has been prized for its clarity and serene blue tones, associated with sailors and poets alike, a stone that evokes safe passage and enduring devotion. This particular greenish blue aquamarine from Nigeria arrives to you as a fresh expression of that heritage, a naturally transparent 1.65 carat trillion shape gem that speaks to both history and the quiet confidence of modern design. At The Natural Gemstone Company we honor that legacy by presenting stones that retain their natural character, and this gem, with no enhancement, preserves the authentic voice of its origin and formation deep within the earth.

The gem’s measured dimensions, 7.62 by 7.82 by 5.88 millimeters, reveal a compact yet substantive presence that translates beautifully into an intimate ring, a classic solitaire pendant, or a refined pair of earrings. Its faint color intensity is a delicate, greenish blue that reads as subtle and cultured rather than overt, and its transparency invites light to move freely through the crystal lattice. Evaluated at eye level, the clarity grade of very slightly included indicates inclusions so minimal they do not detract from overall beauty, and with an excellent polish the facet surfaces are finely finished to a mirror-like sheen. Each of these attributes adds to the sense of an unaltered natural treasure, a piece one might pass from generation to generation, held as both adornment and story.

The trillion cut, triangular yet softened at its points, is central to how this aquamarine expresses light and life. Unlike round cuts that rely on concentric symmetry, the trillion leverages angular geometry and broad, flat facets to create a dynamic interplay of brightness and scintillation. The triangular outline concentrates light toward the center and along each edge, while the carefully proportioned crown and pavilion facets reflect and refract illumination in planes that emphasize both brilliance and internal glow. Aquamarine’s refractive index and modest dispersion mean it does not flash spectral fire like some gemstones, yet the trillion cut amplifies its innate qualities by maximizing return of white light and highlighting subtle shifts in tone. With excellent facet junctions and polish, each plane becomes a crisp mirror, so that movement and changing light reveal new depths of blue and green, while the stone’s transparency allows for a lively, evocative play of light rather than masked color.

This gem’s classic temperament and distinctive cut make it especially suited to those who appreciate tradition rendered with a contemporary sensibility. Set in a timeless three-prong or a bezel that honors the trillion silhouette, the stone will read as both heirloom and modern statement, carrying its Nigerian origin and natural, untreated state into any design with quiet authority. At The Natural Gemstone Company we understand that collectors and connoisseurs seek more than beauty; they seek provenance, integrity, and the continuity of story. This aquamarine, with its clear, faintly hued waters and precisely executed trillion cut, embodies that continuity.
