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.

Lovely, dainty piece. Love that it's adjustable because I usually find bracelets to be too big so this is perfect. My criticism is that my engraving is offset so it isn't in the centre but it's subtle anyway so doesn't bother me too much.

A gorgeous, high-quality bracelet that exudes class and is a lovely friendship bracelet for adults. I have purchased a number of Kula bracelets and they look fab layered with the Biography range. I wear silver/white gold/platinum/stainless steel jewellery so it's great to be able to buy these bracelets in silver as well as the gold and rose gold. Easy to adjust, this fits my slim wrists with loads of room for adjustment for those with larger wrists.
