Using millions of data points, Diamond Bar has determined the fair market value for diamonds. Each diamond you buy, sell, or upgrade is priced fairly and transparently using the Find My Diamond’s Value* tool.

Just like Zillow is for real estate, and Kelly Blue Book is for cars, Diamond Bar allows you to quickly discover the value of diamonds. Each diamond is presented with a chart of historical average prices and comparable diamonds on the wholesale market.
