Rapaport to unveil new pricing tools at JCK breakfast

Better pricing intelligence can change a diamond deal long before a stone reaches a showcase. At Rapaport’s JCK breakfast in Las Vegas, the company will unveil new tools tied to the Rapaport Price List, a move aimed at giving dealers, manufacturers, and retailers faster, more transparent signals on asking prices, negotiations, memo strategy, and market direction.

The breakfast is scheduled for Sunday, May 31, 2026, from 8:00 to 10:00 a.m. in the Marcello Ballroom on Level 4 at The Venetian Expo. Rapaport says CEO Dan Mano will introduce the “New Rapaport” and a suite of new products before Martin Rapaport delivers his annual industry address. Seats are limited, and each guest must register separately, a detail that underscores how closely the trade follows anything that could affect price discovery.

The stakes are high because the Rapaport Price List remains one of the industry’s core reference points. Rapaport says the list is updated every Thursday at 11:59 p.m. ET and serves as a benchmark dealers use to establish diamond prices in major markets. The company also says the list reflects opinion-based high cash asking prices, not transaction prices, which is exactly why any new pricing-intelligence layer matters: if the market gets a sharper read on what is being asked versus what is actually being paid, negotiation power can shift between seller and buyer. Rapaport’s archive goes back to 1978, a long paper trail that shows how deeply embedded the list has been in the trade.

RapNet, which Rapaport describes as the world’s largest diamond trading network, adds another layer to that system. The platform currently lists more than 1.6 million stones and jewelry pieces and counts tens of thousands of members from 103 countries. For a retailer trying to protect margin, or a dealer deciding whether to hold inventory or move it, more granular pricing data could mean fewer guesswork discounts and a stronger sense of where a stone sits in the market. The pear list is also widely used as a guide for fancy shapes, so any changes to the pricing tools could ripple beyond rounds into the broader shape mix.

Rapaport’s breakfast has become a bellwether for those shifts. In 2025, it drew a record 1,000 attendees and featured De Beers CEO Al Cook in conversation with Martin Rapaport, with discussion centered on natural-diamond scarcity, consumer messaging, sanctions, synthetics, and strategy. The debate around pricing itself has also been part of the story: in 2020, the Rapaport Price List moved from weekly to monthly publication after backlash over steep price drops, then returned to weekly publication in June 2020. Against that backdrop, any new tool that promises clearer pricing signals is more than a product launch. It is a potential reset in how the trade argues over value.
