3.80 Ct. Aquamarine from Nigeria

If you are seeking a single stone that will complete a high end gemstone collection, answer the search with this extraordinary turnkey aquamarine from The Natural Gemstone Company. Many collectors and designers come to us looking for a gem that combines transparent purity, refined color, and a cut that reads as both modern and timeless. This 3.80 carat blue aquamarine meets those exact needs. Its trillion shape and precise trillion cut present an architectural silhouette that maximizes brilliance and symmetry, while its dimensions of 10.95 x 11.13 x 6.58 mm offer substantial presence without overwhelming a bespoke setting. The gem is transparent with a faint color intensity that lends it a cool, elegant presence that will pair beautifully with white metals or the warm contrast of rose gold. For the buyer who wants a stone that makes a quiet yet profound statement, this aquamarine solves that brief immediately.

As a gem professional I understand the priorities that matter to collectors. Clarity is one of those priorities, and this aquamarine carries a clarity grade of very very slightly included evaluated at eye level, a grade that speaks to exceptional visual purity and a clean window to the stone core. The excellent polish enhances light return and surface crispness, ensuring each facet plays a role in delivering scintillation and subtle flashes of blue. Importantly for connoisseurs, this gem is free of enhancement, a natural untreated example from Nigeria, and that provenance adds both story and rarity to your collection. Nigerian aquamarine material is prized for its clarity and fresh color, and an untreated specimen of this size and cut is a rare find. The trillion cut concentrates and scatters light in a way that enlarges perceived size and creates a distinctive triangular brilliance, so on the finger or in a display case the stone will read larger than its carat weight might imply.

For the client assembling an heirloom quality collection, or the designer planning an engagement ring that will be passed down for generations, this aquamarine is the perfect solution. It adapts to many settings, from a minimalist three prong solitaire that showcases the clean facets, to a halo design that plays with contrast and adds presence while preserving the stone as the primary focus. The faint blue tone is versatile, complementing both platinum and warmer alloys, and its excellent polish makes polishing and resetting straightforward should you wish to commission future changes. At The Natural Gemstone Company we stand behind the authenticity and natural origin of this gem, and we are ready to provide high resolution images and handling advice so you can visualize the stone in your chosen mounting. If your collection aims to capture pieces that combine aesthetic beauty, geological interest, and long term value, this 3.80 carat Nigerian aquamarine is the conclusive piece that ends the search and begins the legacy.
