Scapolite
Scapolite is a silicate mineral prized by collectors for its exceptional color range.
About Scapolite
Scapolite belongs to the silicate class in the scapolite group (marialite-meionite series) and has the chemical formula (Na,Ca)4[Al3-4(Si,Al)3-2Si6O24](Cl,CO3,SO4). It crystallizes in the tetragonal system and is one of the most visually varied minerals in the collector market.
Identification & care
Specimens usually show prismatic tetragonal crystals, often large; massive, granular. Its color range is broad, including colorless, white, grey, yellow, orange, pink, violet, purple, and rarely green or brown. The luster is vitreous, sub-vitreous, resinous, the streak is white, and specimens range from transparent to translucent. The cleavage is distinct on {100} and {110}. The fracture is conchoidal, uneven, which aids identification.
