Positive experiences: I have emailed customer service on a few occasions and have been pleased with all the responses. One in particular was for a price drop that occurred after my ring was ordered but before it was shipped. They gave me the discount without a hassle. I will gladly continue doing business with them.
My experience with them has one word to describe it, "fabulous". They have the lowest price of any of the big jewelry stores. Combine this with an ultra user friendly interface. Their "SALES" section is extremely one of the best.
