Dolomite specimens for sale

Dolomite is a carbonate mineral composed of calcium magnesium carbonate, often forming rhombohedral crystals and granular masses with a glassy to pearly lustre. It commonly appears in white, pink, or colorless hues and can occur in fibrous or tabular habits, sometimes as coarse aggregates or thin tabular crystals. Notable specimens come from classic carbonate environments in the USA, Namibia, China, the UK, and Spain, where dolomitic rocks and hydrothermal activity have preserved attractive crystal forms and polished surface luster. Collectors value dolomite for its subtle coloration, well-formed rhombohedra, and the way it can display a pleasing internal sheen when cut or polished.
