The International Institute of Diamond Valuation was created to improve customers' experience when they re-sell their diamond jewelry. We strive to make this process as easy and transparent as possible, and to offer the highest possible prices. Here is what some of our customers are saying about their recent experience with us:

Testimonials Updated


"I was very hesitant and nervous about sending an internally flawless diamond ring. Back in 1996 we paid close to $5,000 for this ring. Yet this individual took the time to explain to me how the insurance works. Also, was very patient with my other questions of other gems that were not diamonds. I would recommend this company to all my friends and family!"
