Can You Tumble Calcite? Be Careful and Follow These Tips

The medium and fine are meant to take the minerals down to a smooth finish and shiny polish. This longer process of tumbling, taking a week on each level of grit, works well for minerals like agate, jasper, or quartz, which all have a hardness of seven. However, softer stones like calcite would not survive tumbling for weeks at a time.

Precipitated Calcium Carbonate (PCC)

Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals.
