Marci is a unique jewlery store for diamonds. The customer service is amazing (of course it should be if you're buying one of these babies!), and the diamond selection is among the best I've ever seen. Shopped around quite a bit, including Costco.com and Marci, was able to do some good pricing. They can help you locate the exact item that you're after, if you're looking for a unique stone. A definite must, if you're after a special gift.
