I have been dealing with Carol, primarily, at Wonder Jewelers now for almost four years. I have purchased large loose diamonds, had a custom engagement ring over 5c. made to order, in addition to having them custom make a gorgeous diamond necklace and a beautiful Sapphire ring. My latest purchase just this month was a beautiful 4c diamond necklace for my wife's 60th birthday. In every case, the service has been excellent, the quality outstanding, and the promises were always kept with respect to delivery etc. In every case my expectations have been exceeded upon arrival of the final product. I had been dealing with a wholesaler in New York for many years, and find the quality and pricing to be as good if not better and the service to far exceed my New York contact. I highly recommend Wonder to my family and friends and to anyone taking the time to read my review.
