Query: Excellent product and super service

These rings are absolutely stunning. Well worth the price and look much more expensive than they were as the quality is superb. Even more, the customer service was first class. I needed these on a rush and they were received exactly when I needed them. I made an error about size on one of the rings and they were very accommodating to me, got me what I needed and delivered the second time with flawless perfection. I cannot say enough about the level of service and the quality of workmanship. You've made two people very happy. Thank you! I will definitely be back for more product from these guys.
