A raw prismatic ruby crystal is a natural mineral specimen that preserves the elongated crystal form characteristic of corundum and its authentic surface texture. Ruby is the red variety of corundum, and its pink, red or purplish-red colour is caused by chromium present in the mineral’s crystal structure.
Corundum is exceptionally hard, reaching 9 on the Mohs scale. Rich raspberry, dark red and purple tones, natural growth lines, mineral inclusions and irregular crystal surfaces give each specimen its distinctive character. The unprocessed prismatic form offers an insight into the natural structure of ruby and the characteristics of its formation.
This crystal is ideal for a mineral and gemstone collection, an educational display, an interior accent or as a meaningful gift for someone interested in geology and the natural world. Each specimen is unique; therefore, its shape, shades and surface characteristics may vary. Natural inclusions, cracks, chips and irregularities are features of the mineral’s natural origin and should not be considered defects.
