Best Bitches half heart necklaces. Comes as a set of two necklaces. Each on an 18" sterling silver plated snake chain. Aluminum is a very light weight but super sturdy metal. It will never rust, tarnish or turn color. More Hypoallergenic than sterling silver. Hand stamping is done by hand one letter at a time with a hammer and a shank. Alignment, spacing and depth may occur but this is what makes each piece truly one of a kind.
