Husband wants to buy me a piece of jewelry for my 50th birthday. I'm not a huge jewelry wearer, so it won't be worn every day. We're not loaded, so it won't be diamonds or anything. I've been looking at Swarovski pendants, and I love some of them. Are they good quality, and will they last? Will they turn my neck black? I just don't want him to spend his hard-earned cash on something that quickly loses its sparkle. Any insights you have would be appreciated!
