Calcite Rhomb – Kilo Bag

1 kilo of caclite rhomb mineral specimens, showing typical cleavage and vitreous/pearly lustre. Calcite is a common and widespread mineral with variable forms and colours, best recognized by its relatively low Mohs hardness (3) and its high reactivity with even weak acids: e.g. vinegar, along with its prominent cleavage in most varieties which make it appear as a rhomb shape, (e.g. warped cubes or rectangles). These mineral specimens are ideal for schools, educational and teaching use where bulk quantities may be required for little cost, specimens are supplied are a range of sizes between 40 mm to 70 mm and come in a strong polythene bag by kilo weight and an information card
