Vintage Banded Calcite heart shaped coaster set (6 coasters)
Banded Calcite is a sedimentary rock composed of calcium carbonate (CaCO3). Its distinguishing feature is the presence of thin layers or “bands” of varying colours, typically white, cream, yellow and brown. Banded Calcite often forms in limestone beds and can be used as a decorative stone for many applications, including jewelry and construction.
