Aquamarine is the blue to blue-green variety of beryl, crystallizing in the hexagonal crystal system with a Mohs hardness of 7.5–8. Its luster is typically vitreous (glass-like), and fine specimens range from semi-transparent to completely translucent.
A: A delicately elongated crystal of from Medina, Minas Gerais, Brazil, displaying an ethereal icy-blue saturation with remarkable transparency throughout the tapering prism. I would characterize this piece as possessing a graceful, almost aerodynamic form, terminating in a naturally sculpted etched set of points that catches light with exceptional elegance. Of course this piece also possesses the fantastic hollowing that makes Medina so memorable. Fine internal veils and subtle growth textures create a liquid, glacial appearance. Measuring 5.6 x 1.2 x 1.2 cm.
B. A stout and beautifully striated crystal from Medina, Minas Gerais, Brazil. This specimen exhibits pronounced vertical growth etching and lustrous prism faces, with soft seafoam-blue coloration distributed evenly throughout the crystal. The semi-transparent body reveals intricate internal structures and natural phantom-like textures under strong illumination. Most exciting, the growth is fully etched along one edge of the hexagonal ridge and seems to “terminate” along to the interior of the hollowed core. Measuring 5.5 x 1.7 x 1.1 cm
C. Exceptionally elegant faceted aquamarine showcasing the crisp brilliance and tranquil ocean-blue tones that have made fine aquamarine one of the most enduringly sought-after collector gemstones. Expertly cut by a Master
Gemstone Cutter in Brazil, this cutting amplifies the stone’s exceptional clarity and vitreous luster, producing vivid flashes of icy blue light across the crown facets. The gem displays the clean, luminous transparency and serene coloration associated with high-quality Brazilian material, balancing sophistication with the calming visual character for which aquamarine is renowned. 5.08 ct; 3.5 x 7 x 0.4 cm
