My dd14 likes gold-toned jewellery but is finding that the finish wears off cheap jewellery and turns her skin green (not surprising as it is usually very VERY cheap, supermarket-bargain-rack cheap, she's a teenager). My question is: if I buy her a somewhat more expensive necklace or ring for Christmas, say £15/£25, that says it is gold-plated brass, will the finish wear off that quickly as well? Also, what is gold vermeil? And what about carats? I don't mind spending a bit more for jewelery that will last but she would be freaked out by an expensive item that she might lose.
