5.53 Ct. Blue Aquamarine from Madagascar

This 5.53 carat oval aquamarine from Madagascar, supplied by The Natural Gemstone Company, is cut to precise proportions to optimize the inherent light performance of beryl. The gem measures 13.18 by 10.84 by 7.50 millimeters, yielding an average depth of approximately 62 percent, a proportion that balances face up size with internal light return. The cutting style is faceted with a mixed brilliant design, featuring a brilliant facet arrangement on the crown and a modified pavilion plane. The crown facets are calibrated to maximize return through the table, while the pavilion angles are controlled to prevent light leakage and to direct photons back through the crown. Excellent polish and careful symmetry enhance facet junction definition, producing crisp facet reflections and controlled scintillation across the table and crown.

Optically the mixed brilliant treatment enhances the aquamarine s intrinsic properties of clarity and color, even with a slightly included clarity grade at eye level. The slightly included nature provides minor internal contrast that actually increases scintillation without compromising transparency, since inclusions are minimal and well positioned. Medium color intensity in a cool blue tone is preserved by the lack of enhancement, ensuring that color saturation remains natural and evenly distributed. The oval shape and the ratio between length and width are managed to minimize the common oval bow tie, through subtle adjustments to pavilion facets and girdle elevation. The result is a lively, even return of light, with strong facet flash and gentle body color when viewed face up, and pleasing depth and brilliance when viewed at angles. For connoisseurs who value technical cutting, this aquamarine demonstrates meticulous lapidary control, from facet placement to polish, delivering efficient internal reflection and a clean, natural blue that performs exceptionally in mounting.
