135.69 Ct. Greenish Blue Aquamarine from Brazil

I first saw this aquamarine as a rough stone unearthed from one of Brazil most storied pegmatite veins, a piece that already carried the quiet of ancient water trapped in mineral form. From its origin in Brazil this 135.69 carat oval shape gem began a long and careful passage, moving from miner to sorter to cutter, each hand along the way honoring what nature had offered. The Natural Gemstone Company guided that journey with an eye for provenance and integrity, and today the result is an AGL certified Blue Green aquamarine of exceptional scale and character. Its dimensions measure 29.90 by 39.87 by 20.03 mm, and it presents a transparent, greenish blue body color with a light color intensity that reads calm and luminous rather than saturated and heavy. The certification by AGL confirms the gem origin and the treatments it underwent, and it stands as a testament to both the mineral history beneath Brazilian soil and the deliberate decisions made to reveal its finest face.

The transformation from rough to faceted gem was led by master cutters who selected a mixed brilliant cutting style to reconcile two aims that this stone demanded. With its generous size and inherent transparency, the cutter chose a mixed brilliant arrangement to preserve broad, serene color across the table while introducing a pavilion pattern that returns lively flashes of light. The result is a faceted oval with a balance between broad color plains and scintillating facets. At eye level the clarity is graded eye clean, which means under normal viewing the stone reads transparent and pristine without visible inclusions interrupting the flow of color. The polish is excellent, a finish that allows light to enter and exit the gem with minimal interference, and the enhancement recorded is heat treated, a common and stable procedure for aquamarine that softens green undertones and clarifies the blue while remaining fully accepted by the trade. Every facet was planned to respect the stone dimensions and to maximize the gem’s natural properties.

When I describe the reflective qualities of this aquamarine, I like to position it among its peers and relatives so you understand the nuance of what you will see when you hold it. Aquamarine belongs to the beryl family, and within that family it tends to offer a vitreous luster coupled with a calm, watery brilliance rather than the fiery dispersion that dazzles from diamonds. Compared to emerald, which shares a beryl lineage, this aquamarine is far more transparent and lively at this size because emeralds often carry inclusions that reduce light return and create a softer, oilier glow. Against blue topaz, which can present sharp sparkle and a brighter crown due to slightly higher refractive indices, this aquamarine offers a more refined, soothing radiance, an effect that reads as depth and clarity rather than brash flash. Tourmalines can display intense pleochroism and deeper color zoning when viewed from different angles, a trait that creates dramatic color shifts, while this aquamarine reflects light consistently with subtle shifts between blue and green depending on angle and light source. The mixed brilliant cut enhances scintillation so that when the stone moves it sends out crisp pinpoints of light across a broad, softly colored field. This makes the gem especially compelling in natural daylight and under soft indoor lighting, where it can appear to capture a horizon of water and sky with each tilt.

Thinking about the final relationship between gem and wearer, imagine a large, open setting that allows light to flood the table and pavilion, or envision this stone as the centerpiece of a museum quality pendant where every facet can tell a story. At 135.69 carat and with dimensions near 40 mm across the length this aquamarine will dominate any setting with dignified presence, and the eye clean grade ensures that your gaze is always invited into clear depths rather than diverted by internal marks. The heat treatment used was honest and industry standard, and the AGL certificate that accompanies the stone from The Natural Gemstone Company confirms both the origin from Brazil and the stone treatments, giving collectors and designers the assurance they need. As a salesperson and as someone who cares for gemstone stories, I invite you to consider not only the physical statistics of 29.90 by 39.87 by 20.03 mm and 135.69 carat, but also the narrative of transformation that makes this greenish blue aquamarine singular. When you hold it you will be holding a piece of Brazilian geology and human craft combined, a gem that has been coaxed to reveal a serene, reflective beauty that compares favorably to its peers with a clarity and scale that few aquamarines can match. If you would like further information about setting options, mounting suggestions, or to arrange a private viewing through The Natural Gemstone Company, I would be pleased to assist you in making this aquamarine part of your collection.
