1.20 Ct. Blue Aquamarine from Brazil

This is a beautiful transparent 1.20 carat oval blue aquamarine, offered by The Natural Gemstone Company, with precise measurements of 7.97 by 6.18 by 4.37 mm, faceted in a mixed brilliant cut and finished with an excellent polish. The gem exhibits a light color intensity that reads as a delicate, cool blue when viewed face up, and the mixed brilliant cutting style provides a pleasing combination of scintillation and broad flashes of light. Clarity is graded slightly included evaluated at eye level, a realistic and honest assessment that reflects the natural character of aquamarine crystals. Origin is Brazil, a well known source for aquamarine that produces material with clean crystal structure and attractive pastel tones. The enhancement is heat treated, a standard and stable practice used to refine and remove greenish hues, and disclosure of this treatment is included to help an educated buyer make an informed decision.

Size and clarity together make this stone particularly well suited for a statement piece in fine jewelry, because the 1.20 carat weight and the oval dimensions create a strong face up presence on a ring or pendant, and the mixed brilliant cut enhances perceived size through efficient light return. At 7.97 by 6.18 mm the oval silhouette reads larger on the finger than a round of equivalent weight, and the shallow to medium depth of 4.37 mm preserves brightness rather than hiding color in a deep pavilion. The slightly included clarity grade means that inclusions are minimal and do not distract from the gem when seen in typical wear conditions, so the stone maintains an open, transparent appearance that is desirable for a centerpiece. With an excellent polish the facets meet crisply, which maximizes brilliance and ensures the gem will stand out under modest and strong lighting alike.

From a gemological perspective, the clarity grade slightly included evaluated at eye level indicates inclusions that are observable to a trained eye under careful inspection, but which most often remain unobtrusive in everyday wear, and in aquamarine such inclusions rarely affect structural stability. Heat treatment is disclosed and common in aquamarine, used to improve blue tone by reducing green or yellow undertones, and it is considered an accepted enhancement in the trade because it is stable and permanent under normal conditions. The mixed brilliant cut combines elements of pavilion brilliance and crown fire, so the cutter has balanced optical performance with conservation of weight, yielding the attractive face up size and lively play of light seen in these photographs. The Brazilian origin adds provenance, since Brazil, particularly regions such as Minas Gerais, has a long history of producing gem quality aquamarine, a factor that many informed buyers consider when assessing desirability and potential resale.

For collectors and designers seeking a refined yet noticeable centerpiece, this aquamarine represents an excellent balance of size, clarity, and optical performance, and it benefits from full disclosure of its enhancement and origin by The Natural Gemstone Company. Aquamarine has a practical durability with a Mohs hardness around 7.5 to 8 which makes it suitable for daily wear when set thoughtfully, and routine care involves avoiding harsh chemicals and protecting the gem from hard knocks. We provide detailed images and measurement data to support appraisal and design choices, and our team can advise on settings that will emphasize the oval face up presence and protect the gem while maximizing brilliance.
