Bracelet with tourmaline and sapphire
This bracelet has a pyroelectric charge. This phenomenon, first observed by Theophrastus in 314 BCE, occurs when tourmaline and other natural materials are heated. Even body heat can cause a change in charge. You won't notice this, and the charge slowly dissipates. However, the green tourmaline in this bracelet is especially beautiful. It is set with green-blue sapphires and beads with a handmade 18k yellow gold hook, and it was made for Ellen.
