Who We Are
The International Institute of Diamond Valuation (IIDV) specializes in the valuation and purchase of diamond jewelry.
We’re a division of De Beers Group, the world’s leading diamond company, which has been operating for more than 125 years and is widely considered a benchmark for integrity in the diamond industry.
Our laboratory is located in the heart of New York City’s Diamond District and is staffed by a team of expert gemologists.
IIDV was established in 2014 in response to research revealing that consumers felt they were being treated unfairly during the jewelry-selling process.
During our own research experiences, we’ve witnessed many instances of unsatisfactory consumer experiences with some online buyers and jewelry retailers, including:
Low price offers (sometimes less than 10% of wholesale value)
No price offers (regardless of jewelry value)
Inconsistent price offers (different buyers at same store giving different offers)
Leading questions to sellers that allow professional buyers to offer less
Lack of quality analysis of diamonds.
Our research suggests that customers are seeking:
Leading market prices
A reputable brand and trustworthy jewelers to assist in providing respectful service
Greater transparency and hassle-free valuation process.

Improve diamond identification through the application of industry-leading technologies.
