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.
The bulbous carnelian heart is about 4.0 x 4.5cm.
Other names for the mineral carnelian are coralin/coraline, flesh agate or blood agate; in wholesale carnelian is occasionally called serdolik.
