I am thrilled with the 6 carat diamond eternity ring I recently purchased from Dino at the Diamond Mansion! This is a surprise for my wife, we are celebrating out 30th anniversary next month. The ring is gorgeous, and each of the 14 stones came with a GIA rating folio. Dino was great to work with, and did everything that he said he would and more. I was honestly a bit nervous ordering such a big ticket online, from the opposite side of the country (i'm in Boston), but everything went very smoothly, and I am happy to highly recommend Diamond Mansion to anyone reading this review!Read More

It was a pleasure to do business with Diamond Mansion. They made my ring purchase a lovely experience, because they took the time to ensure that the ring was perfect and that it arrived on time for my special event. I have recommended their company to my friends and hope to conduct more business with them in the future.Read More
