Orange calcite is a coloured variation of the mineral calcite (calcium carbonate), it has an orange hue to it due to the presence of haematite impurities, these particular specimens exhibit a more crystalline, fine grained crystal texture in which the individual crystals are too fine to be seen, however, the crystal have grown and interlocked with each other to form a large mass, known as ‘massive’. Calcite its self is among the most common mineral found naturally, quite often as mineral deposits but also in many sedimentary rocks, either as a cement or as crystal inclusions, particularly limestone. It is well known for being a fairly soft mineral, easily scratched, coming in at 3 on the Mohs scale of hardness. These particular pieces are suitable for enthusiasts and educational use, both because of the calming blue colour and also the crystal structure and as a means to display the various colours a mineral can be found. Supplied in lots of 1kg, in a heavy duty polythene bag with information label.
