They come supplied in a polythene bag with an information label and are ideal for mass purchasing, such as for museum information tasks, educational use and more.
Honey calcite mineral specimens from Mexico which exhibit a yellow to orange colouration due to impurities of iron from the mineral hematite. The specimens are crystalline in nature and can exhibit a rough rhombic form as expected of calcites. They are translucent, letting some but not all light through, which gives them an eye catching ‘glow’. The samples are ideal for enthusiasts, hobbyists and collectors and are available in various sizes. This honey calcite is available by weight, starting from 500 grams, and is suitable for lapidary, educational and enthusiasts use. The pieces vary from 20 mm to 100 mm, though most pieces will sit in-between and come supplied in a polythene bag with a label.
Orange calcite mineral samples supplied by weight, this rich orange variation is due to the presence of iron hematite impurities within the crystals.

This orange calcite is available by weight, starting from 500 grams, and is suitable for lapidary, educational and enthusiasts use. The pieces vary from 20 mm to 100 mm though most pieces will sit in-between and come supplied in a polythene bag with a label.
