The Buyer

Pricing

How a diamond is priced — from the Rapaport list to rough parcels, rare types and the discounts that move a number.

Pricing

A diamond is worth what someone will pay for it — yet every week the trade publishes the lists that turn that truth into a number.

Pricing

Begin with the Rapaport base price — then adjust up or down for cut, the placement of inclusions and the pull of fluorescence.

Pricing

Pricing the unpolished stone — ADTEC lists, the costs and risks discounted from the base, and the difficult art of buying parcels.

Pricing

Why the largest stones leave the price list behind — and answer instead to rarity, the saleroom and the patience of the few who buy them.

Pricing

The nitrogen-free 1.8% — the purest diamonds nature makes, the most sought after of all, and the names that set records at auction.

Pricing

Stones cut to exact, computer-monitored proportions for jewellery and watch work — and why that precision carries a premium.

Pricing

Priced off the Rapaport pear list — and why Princess, Cushion and Radiant can command a premium over the market.
