Dated references
Every published edition has its place in the timeline. New lists appear first, and previous editions remain available for a consistent comparison.
BUILT FOR A CLEARER VIEW

Rap Price makes diamond pricing easier to read, compare and revisit. We bring international market reference prices into dated lists and a practical calculator, giving jewellers, traders and buyers a clearer starting point for an informed conversation.

A single figure captures one moment. Comparing editions reveals the movement: where reference values rise, where they soften and which combinations remain unchanged. Our archive keeps earlier dates available, while changed values appear in bold in updated PDFs.
Round & Pear, clearly separated
Separate price sheets keep round and pear-shaped natural diamonds easy to navigate by weight range, colour and clarity.
From reference to calculation

Perspective before a decision.
Diamond prices reflect more than a table: supply, demand, the individual stone and the terms of a transaction all matter. Rap Price presents published reference data with its edition date. It is an independent pricing tool; reference prices are not a guaranteed sale price or a live exchange quotation.
