Sodalite belongs to the Feldspathoid group of minerals, its rich blue colouration derived from the sulphur-bearing compounds within its Sodium Aluminium Silicate structure. Unlike Lazurite (its visual cousin and primary component of Lapis Lazuli) Sodalite forms in silica-undersaturated igneous rocks where Sodium-rich magmas cool under specific chemical conditions. The characteristic white veining represents Calcite or other secondary minerals filling fractures and cavities within the Sodalite mass, creating the graphic patterning that distinguishes the finest specimens.
Brazil's Bahia state produces Sodalite of exceptional quality, the deposits yielding material prized for both colour saturation and workability. The deep blue displayed here represents optimal conditions during the mineral's formation within Nepheline Syenite host rocks. Darker patches visible across the surface indicate areas of higher iron content or associated minerals within the original mass.
The obelisk form showcases Sodalite's capacity to accept a high polish while preserving the visual complexity of its natural veining.
