4.71 Ct. Blue Aquamarine from Brazil

This transparent blue aquamarine weighs 4.71 carats and is presented in a classic emerald cut, with precise dimensions of 9.69 x 9.12 x 7.07 mm. The stone exhibits medium color intensity that balances a soft yet distinct sea blue, and the excellent polish enhances its clarity and facet definition. Clarity is graded as very very slightly included evaluated at eye level, indicating that the stone appears clean to the unaided eye while retaining minimal internal characteristics under closer inspection. The cut is executed to emphasize broad step facets, producing an elegant, geometric appearance and stable color distribution across the table. This specimen has been heat treated to optimize its color, and its documented origin is Brazil. The Natural Gemstone Company provides full disclosure of the enhancement and origin in keeping with industry best practices.

The gem weight of 4.71 carats is a primary driver of this aquamarines market appeal and relative rarity. Aquamarines of similar color and clarity become progressively less common as size increases, so a near five carat emerald cut example offers a notable premium in both desirability and price per carat compared with smaller stones of comparable quality. The substantial proportions, combined with the step cut and excellent polish, yield a strong presence suitable for a centerpiece ring or a bespoke pendant, while retaining practical wearability. Because the stone is transparent with only very minor inclusions at eye level, the visual impact is maintained at larger scales without the common trade off of increased visible characteristics. For buyers and designers assessing value, the 4.71 carat weight enhances collectability and flexibility for higher end settings, and contributes materially to replacement and appraisal considerations. The Natural Gemstone Company is available to provide additional documentation, measured images, and guidance on setting recommendations to ensure the stone is showcased to best effect.
