Impressive natural Afghanite mineral specimen featuring a substantial deep cobalt-blue crystal formation prominently exposed within a contrasting creamy white calcite-rich matrix. The Afghanite displays strong saturated blue coloration, defined angular crystal faces, and visible natural growth striations. Additional blue mineralization extends through portions of the surrounding matrix, accompanied by gray mineral areas and small metallic-looking inclusions that add visual complexity.<br><br>The dramatic contrast between the intense blue Afghanite and pale crystalline matrix makes this a particularly striking cabinet specimen. Natural fractures, irregular edges, mineral contacts, and surface variations are present throughout and are characteristic of an unpolished geological specimen. Displayed from multiple angles, the piece offers attractive color and mineral structure on several sides.<br><br>Ref: AB5750<br><br>Weight: 1,723 ct<br><br>Dimensions: Approx. 4 x 7 in.
