My fiancee and I had the good fortune to find a REALLY great internet vendor where the personal service just floored us. We can only hope that the businesses catering to our actual wedding are half as attentive. The company is DiamondWholesaleCorporation , out of Canada. We researched carefully for about 6 weeks before finding them, and dealt with several internet and B&M vendors before making the decision to go with DWC. They were the only company we dealt with that had actual cutters available to contact, and we were assigned a single sales rep who was incredibly prompt and detail-oriented. They didn't barrage us with lists of hundreds of diamonds, but instead spent an inordinate amount of time on the phone with us to learn about what we wanted. We really felt as though we had our own "personal shopper" through about ten phone calls and many more emails. Our purchase was a stunning loose oval 1.01/D/SI1 which was priced (as we know from exhaustive shopping) a good $1,000 less than the most fair price we found at any B&M. The independent appraisal rang true to the same. We are extraordinarily pleased.
