I stumbled upon Dino’s site when looking for an emerald cut diamond eternity band ring. I reached out to Dino via email as I wanted to inquire about customizing a ring I saw on his site. Dino was an absolute pleasure to work with. I was very clear about what type of diamonds I wanted used in my ring and Dino assured me he would get only the best of the best. He even located all GIA certified diamonds as that was another request of mine. He completed the ring and had it shipped out to me to the exact day that he had told me it would take to get the ring done. To say I am happy with this ring would be an understatement. Dino is a man of integrity and honesty and I will absolutely be back to purchase more jewelry from him in the future. His pricing is very fare. I assure you that you are in the best of hands at Diamond Mansion.Read More

I wanted to upgrade the setting for my wife's engagement ring. I did a google search and diamond mansion came up as the best reviewed and recommended. I just am seriously so happy I found this place. I was very nervous to take my wife's stone and leave it somewhere and not only did they make me super comfortable, but they gave the best service overall. They designed the setting in 3D and made it exactly to my instruction. The pricing was also way less than the original setting I got, but I got more diamonds and the color was very good as well.Read More
