Sodalite, with its distinctive deep blue colour is one of the components of Lapis Lazuli and very rare. DANIEL SMITH Sodalite is the finest quality and deepest blue that comes from Greenland and the Italy’s Mt. Vesuvius. In watercolour, the inky colour of this semi-precious stone granulates as it dries, layering a blue-black textural surface on a smooth blue-grey undertone. Low staining, lightfast and semi-transparent, Sodalite creates a three-dimensional quality as it dries.
