Derco's specialty are diamonds and all their jewelry looks top notch. I especially like their "trade-up" program where if you buy a diamond stud earrings from them, you can bring them back later and apply the full price (minus tax) to the purchase of a bigger set of earrings. (My wife also like that too). Aside from that, they have very good service - they'll take care of you when you go in - clean you jewelry for you, even if you didn't buy it there.
