Actually no star earned but had to give one to rate. At the chain. .. Can only say very small! My girlfriend had after three days NEN bad rash and is usually not sensitive in terms fake jewelery! If the this jewelry have iwas to do with swarovski I doubt very much! My opinion, prefer to buy NEN ring or chain ne from the gumball machine for 50 cents than this "gem"! Sellers should be ashamed! !!!!!!!!!!!!!!! Just do not support and let rip. Return does not make sense because of the United Kingdom
