10.86 Ct. Aquamarine from Brazil

This exceptional Blue aquamarine from The Natural Gemstone Company arrives as a rare and refined statement piece, standing apart from the more common offerings in the market, such as standard ovals and rounds. At 10.86 carats, this transparent gem occupies a premium weight class for aquamarine, providing a presence that few stones can match without resorting to lower color or clarity. The asscher octagon shape and asscher cut create a distinctive hall of mirrors effect with step facets that emphasize symmetry and architectural beauty, unlike brilliant cuts that trade clarity for sparkle. Where many aquamarines on the market rely primarily on size to make an impression, this example blends generous carat weight with intense color intensity and a clarity grade of very slightly included evaluated at eye level, delivering both visual impact and gemological quality. Collectors who are accustomed to handling a wide range of aquamarines will notice the superior balance here, a stone that reads as refined and collectible in both loose form and when set into high end jewelry.

Technically this gem checks every box for discriminating buyers, beginning with its GIA certification, which provides independent verification of origin, weight, and treatment, a level of assurance that many sellers cannot offer. The dimensions of 12.69 x 12.33 x 10.13 mm represent a well proportioned pavilion and crown relationship for an asscher octagon shape, yielding excellent light performance and consistent brilliance across its table. The excellent polish enhances facet definition and creates crisp reflections, which elevate the perceived depth of the intense blue tone. Heat treated enhancement is a widely accepted and stable practice for aquamarine, applied to bring out the stone s natural blue while maintaining clarity and durability, and the GIA report documents this treatment so buyers know exactly what they are acquiring. Compared to other market choices that may carry undependable proprietary treatments or lack recognized certification, this piece offers transparency and confidence, making it suitable for collectors who value resale liquidity and provenance.

From a collector s standpoint this aquamarine offers a rare combination of visual elegance, technical pedigree, and investment sensibility, and it fits effortlessly into a high end gemstone collection alongside top quality sapphires and emeralds. Originating from Brazil, a source known for producing some of the world s finest aquamarines, this specimen benefits from natural color potential and crystal clarity that are often absent in commercial grade material. The asscher cut is less commonly seen in aquamarine than in other gemstones, which contributes to its uniqueness and desirability, while the size and proportions make it versatile for bespoke jewelry commissions or for inclusion in a display collection. The Natural Gemstone Company stands behind this stone with full documentation and careful handling, offering collectors a confidently sourced piece that compares favorably to offerings that sacrifice either color saturation, polish quality, or certification to achieve lower prices. For the buyer seeking a statement aquamarine that marries aesthetic refinement with verifiable quality, this 10.86 carat asscher octagon from Brazil represents an elevated choice, a stone that will hold its appeal and remain a centerpiece of a high end collection for decades to come.
