Market Intel
for Diamond Buyers

Diamond Desk is built to help you effectively negotiate any diamond purchase. We monitor the global natural diamond supply, uncover new listings, track wholesale pricing, and maintain a rolling 90-day record of unsold “stale” diamonds so you know which ones to negotiate hard. You’ll get 50 real-time appraisals per month ($2 each thereafter) that show six current GIA market comps, so you can definitively prove whether a price is fair or not, and you can download our inventory data anytime to back it up.
