Candle yay, jewelry nay

I have purchased so many of these candles now, people love them. The candle itself always smells absolutely wonderful. They burn for a really long time and I love that they are soy based which burns much nicer and you dont have all the black soot around the glass jar. All of the jewelry I have received has been from the $75.00-$150.00 range and every single one of them has turned my finger green. I am not sure how they get away with a ring costing 150.00 when it is plated and turns your finger green, but they are such terrible quality. So my quality rating is a 3 because the candle is great quality, the stuff that comes in it is awful. I am scared to try the necklace or bracelet or any other product because I wouldnt want more terrible jewels.
