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.

I bought this pendant for my daughter for her birthday. I had it engraved and she asked for a picture of her puppy to be put in it. The pendant arrived very quickly in excellent condition and my daughter was thrilled with it. It looks beautiful on her.
