Physical properties
Hardness: 6-7 (Mohs scale); Color: Neon pink (artificially dyed) with black spots; Luster: Vitreous to dull; Crystal structure: Microcrystalline; Cleavage: None visible in polished form; Specific gravity: 2.5-2.7
Formation & geological history
Formed from molten rock (magma) that cooled slowly enough to allow minerals to crystallize, resulting in a fine-grained igneous rock. It is naturally white/cream with black spots; the vibrant pink color is the result of post-extraction dyeing.
Uses & applications
Primarily used for decorative purposes, beads, cabochons for jewelry, pocket stones, and metaphysical practices.
Geological facts
Despite being called 'Dalmatian Jasper', it is actually an igneous rock (aplite), not a sedimentary jasper. The black spots are composed of the rare amphibole mineral Arfvedsonite rather than tourmaline as commonly mistaken.
Field identification & locations
Identify in the field by its fine-grained white groundmass and distinct black 'dalmatian' spots. For collectors, dyed specimens like this one are easily identified by colors that do not occur in natural stones, such as hot pink, electric blue, or lime green.
