Specimens of Lapis Lazuli, collected from Afghanistan. Despite beliefs of lapis lazuli being a mineral and gemstone, it is in fact a metamorphic rock. Lazurite is the primary mineral that contributes to its distinct blue colouration. Calcite and pyrite are the other constituent minerals that make up this rock. Specimens come in lots of 1kg, in a heavy duty polythene bag with an information label. Pieces come in various sizes.
