Negotiation Intel
for Diamond Buyers

Diamond Desk is built to help you effectively negotiate any diamond purchase. We monitor the global natural diamond supply and maintain a regularly updated hotlist of the most significant price drops relative to market levels. We also 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.

You’ll walk into any diamond negotiation with the upper hand anywhere in the world. Download our sample data and a verifiable sample appraisal to see if our format works for you.

Recipients are expected to understand and comply with all applicable import requirements.
