What Our Customers Think

“The valuation function told me what my diamond was worth, the retail value, not what those pawn brokers told me.”

Vanessa, New York

“Most jewelers tried to offer us less than the wholesale price for our existing diamond, and then charge us a premium for the new diamond.”

Greg, United Kindom

“I'm super happy with the deal that I got, and with this money I'm planning to take my mom on a family holiday. I can't wait!”

Stephanie, New York

“I went to a bunch of jewelers and searched online to find the perfect diamond. I was looking for the best deal I could find for the specs I wanted.”

Shane, Melbourne
