The story behind the stone…

Greek legend says that while Venus was sleeping, Eros cut her nails and left the pieces scattered on the ground. As no part of a heavenly body can die, Moirae - the goddesses who controlled the destiny of everyone from the moment they were born until they died - turned the translucent objects into onyx.
