These 6mm Carnelian balls sit atop sterling silver stud fittings.
Carnelian is a stabilizing stone that has the useful property of cleansing other crystals. Medically, it is linked with fertility, and stimulates the metabolism. It is useful to those with diseases such as arthritis, rheumatism, neuralgia and depression. (Crystal attributes taken from The Crystal Bible, by Judy Hall)
