6.28 Ct. Blue Aquamarine from Brazil

This oval shaped aquamarine presents a transparent bodytone, weighing 6.28 carat, with precise dimensions 15.43 x 11.64 x 5.96 mm, and originates from Brazil. The stone has been faceted in a mixed brilliant cut, employing brilliant style crown facets combined with a modified pavilion geometry to optimize light return and scintillation while preserving table size. The cutter has emphasized pavilion angles and facet junctions to create even light dispersion across the face, and the excellent polish produces crisp facet reflections and high surface luster. Color intensity is assessed as light blue, with consistent saturation throughout the stone, and the clarity grade is very slightly included when evaluated at eye level, indicating minute natural inclusions that do not materially impede transparency or brilliance. Enhancement by controlled heat treatment has been used to stabilize and subtly refine the blue hue, a standard practice for aquamarine that improves color consistency without affecting structural integrity. The overall cutting and finishing demonstrate careful material allocation from rough to yield a balanced profile suitable for both classic and contemporary settings, and The Natural Gemstone Company assures documented origin and treatment disclosure.

From a durability perspective this aquamarine is a member of the beryl family, registering approximately 7.5 to 8 on the Mohs scale. This places it significantly harder than common jewelry minerals such as quartz, which is 7, and slightly less hard than topaz at 8, and well below corundum and diamond which are 9 and 10 respectively. The practical implication is that the gem offers good resistance to everyday scratches and abrasion, making it appropriate for rings, pendants, and bracelets when set with protective design considerations. For optimal long term performance I recommend bezel settings or protective halos for rings, or secure prong settings for pendants and earrings, to mitigate the risk from sharp knocks to the girdle or table. Routine care involves gentle cleaning with warm soapy water and a soft brush, avoiding ultrasonic cleaners if the mounting or clarity characteristics raise concern, and avoiding exposure to harsh chemicals. For clients seeking a technically refined aquamarine with balanced optical performance, reliable treatment disclosure, and practical wearability, this specimen from The Natural Gemstone Company represents a well executed choice.
