It was our 10th year anniversary, we live in Florida and my husband was looking for a jeweler to design a three stone yellow diamond ring. We selected Diamond Mansion for their excellent ratings and ease of online selection. Dino was awesome to work with - though we were particular, through the process Dino continued to provide design and stone options until we were satisfied. The ring is absolutely spectacular! Thank you, Dino.Read More

What a great experience -- excellent customer service (Dino), constant communication, accurate design illustration, and best of all they delivered an incredible product (Men's 1 crt. Platinum Ring).I buy a ton of stuff online, but was still a bit reluctant to have custom jewelry made, but this worked out amazing -- high quality of craftsmanship. Well done Diamond Mansion.Read More
