13.26 Ct. Aquamarine from Brazil

One transparent oval aquamarine, weight 13.26 carats, measures 17.00 by 15.08 by 8.10 mm, with a mixed brilliant cut and an excellent polish. The stone presents a medium color intensity of blue, consistent with quality Brazilian aquamarine, and displays clarity graded as included, evaluated at eye level. Enhancement disclosed, heat treated to refine tone and color uniformity. The proportions and careful cutting yield a gemstone that balances surface brilliance and depth of color, offering a clear visual presence without overstating saturation.

The mixed brilliant cut complements the oval outline by combining a faceted crown optimized for scintillation with a pavilion designed to return light efficiently. This cutting approach, together with the excellent polish, produces measured sparkle across the crown facets while preserving the aquamarine response to diffuse light. Inclusions are present at eye level but do not detract from the stone geometry or overall light performance. The transparency and facet symmetry accentuate the blue hue in a way that works well in both closed and open settings, making the gem adaptable to a variety of mounting techniques. With a Mohs scale hardness of 7.5 to 8, aquamarine is durable enough for regular wear when set with appropriate protective design, and the gem responds well to standard jewelry maintenance routines to preserve lustre and surface integrity.

Owning this aquamarine represents an investment in beauty and craftsmanship that extends beyond its immediate aesthetic appeal. The origin, Brazil, is recognized for producing aquamarine crystals with stable color and pleasing clarity, and the heat treatment applied here is a conventional, accepted enhancement that improves marketable tone while maintaining structural integrity. The mixed brilliant execution and superior polish reflect skilled lapidary work that enhances the intrinsic qualities of the crystal, converting rough potential into a finished gem with consistent light behavior and pleasing proportion. At The Natural Gemstone Company, attention to provenance, treatment disclosure, and cutting standards is integral to how gems are selected and presented. The result is a gemstone that offers long term value through enduring design, honest specification, and the kind of workmanship that supports both personal enjoyment and potential future resale or estate considerations.
