1833ct Natural Aquamarine Crystal in Matrix

Updated September 22, 2026

Substantial natural aquamarine gemstone specimen displaying attractive icy blue to deeper blue crystalline areas throughout a contrasting dark gray-black and white mineral matrix. The specimen presents a rugged, naturally fractured formation with numerous translucent sections that catch and transmit light, giving the blue material considerable visual depth.<br><br>The aquamarine appears in broad crystalline masses rather than as a single isolated terminated crystal, with shades ranging from pale blue and blue-gray to stronger ocean blue. Dark mineral inclusions and matrix sections provide dramatic contrast, while lighter whitish crystalline areas create additional texture across the specimen.<br><br>Shown from multiple angles, the piece has an irregular block-like natural formation with exposed crystal faces, cleavage surfaces, internal fissures, and varying degrees of transparency. An impressive display specimen for a mineral, gemstone, or geological collection.<br><br>Condition: Natural rough and unpolished specimen with inherent fractures, cleavage, inclusions, irregular edges, contact areas, and matrix material associated with its natural formation.
