1.70 Ct. Greenish Blue Aquamarine from Brazil

This exquisite transparent aquamarine from Brazil is an object of refined rarity, a singular treasure that embodies the quiet elegance prized by collectors and connoisseurs. We present a 1.70 carat, radiant shape gem, with precise proportions that measure 8.68 by 5.51 by 5.16 millimeters, a compact yet commanding presence amenable to bespoke jewelry creations. The radiant cut has been executed to bring both sparkle and depth to the greenish blue hue, catching light with each facet plane, while the excellent polish gives the surface a silky lustre that communicates quality at a glance. At The Natural Gemstone Company we curate only the most compelling specimens, and this aquamarine is offered with the deliberate restraint of limited availability, reserved for those who seek something unique and distinct from mass produced stones.

What sets this gem apart beyond its color and cut are the internal features that make it unmistakable, inclusions that function as the stones own signature. Evaluated at eye level as slightly included, the internal character is both visible and charming, composed of delicate growth lines and tiny mineralized accents that trace the gem through its geological history. These inclusions are not flaws in the common sense, they are natural fingerprints, they are map lines of formation and pressure and time, each one adding provenance and personality. When mounted in a custom setting, these internal hallmarks become part of the narrative of the piece, a private conversation between the wearer and the earth, a reminder that true rarity is accompanied by a story written into the crystal itself.

Color is the soul of aquamarine, and this particular stone offers an intense color intensity that is simultaneously vivid and refined, a greenish blue that calls to mind coastal depths under a clear sky. The color has been enhanced by heat treatment, a stable and widely accepted enhancement that deepens tone and removes unwanted overtones, allowing the natural color to sing more purely. Heat treatment for aquamarine is a standard practice in the trade, it is routinely employed to reveal the finest expression of a stone, and it does not diminish the gemmatic integrity or the long term beauty of the piece when performed by skilled hands. What remains is a gem that projects a rare saturation for its size, perfect for creating a focal point in an engagement ring, a pendant, or an heirloom brooch that will be cherished for generations.

Because each inclusion and each facet arrangement is unique, this aquamarine is inherently limited in its equivalence, there is no exact twin, and owning it is an act of joining select company with few peers. Our recommendation for this 1.70 carat radiant is a bespoke mounting that respects the stone rather than overwhelms it, a setting that allows the light to enter and emphasize the interplay between the radiant cut and the internal features. Consider a classic four prong arrangement in platinum for maximum brilliance, or a tailored halo in warm gold to contrast the greenish blue and draw attention to the intense color intensity. At The Natural Gemstone Company we offer concierge level services to design a setting that highlights the slightly included clarity as a point of character, transforming what might be labeled an inclusion into a celebrated, identifying emblem.

Acquiring this aquamarine is an opportunity to claim a gem that is at once geological, personal, and rare, it is a piece for those who value authenticity and the stories that natural stones carry. We hold only a select number of such specimens, and each is presented with full disclosure and expert guidance, including its origin in Brazil, its precise dimensions, its radiant cut and excellent polish, and its enhancement by heat treatment. If you are drawn to the idea of owning a gem with visible, beautiful inclusions that act like a signature from the earth, please contact The Natural Gemstone Company for a private consultation, we will arrange detailed views and bespoke design options to ensure this aquamarine is set in a manner worthy of its distinct character.
