The small bulbous orange calcite hearts are about 4.5 x 4cm.
The worldwide spread of the heart symbol through art, playing card and religious heart worship has made it probably the most popular non-geometric symbol. To this day, the heart is considered the sign of love and partnership.
Particularly bright, yellowish orange calcite is also called lemon calcite.
Other names for calcite are calcite/calcareous spath, limestone, double spath and sea chalk. The vernacular also calls calcite a leg-breaking stone. Of the various possible spellings, e.g. calcite, calcite, calcite or calcide, the spelling calcite, which is in common use in the wholesale trade today, has prevailed.
