With my first order, I wasn't sure about the setting that I'd chosen. MoissaniteCo graciously agreed to an exchange even though I had mistakenly removed the security tag. They were reassuring and patient in their responses to my inquiries and the exchange transaction was handled very quickly and smoothly. I've since placed another order and just received my rings. I'm very happy with the quality of workmanship and the beauty of the AGS0 Moissanite stone for all the rings that I've received. The shared prong eternity ring is beautiful and very sparkly. I live in Canada and always received my order the day after shipment. I would not hesitate to recommend MoissaniteCo.
