It is designed for professionals who price diamonds regularly as part of their daily workflow and need fast, accurate, Rapaport-based calculations available on a mobile device.

How accurate are the diamond prices calculated inside DiamntX?

DiamntX calculates prices using the official Rapaport weekly price list, the same benchmark the global diamond trade relies on. Your input of shape, color, clarity, carat weight, and discount percentage produces the exact Rapaport-accurate diamond price per carat with no estimates, no averages, and no approximations.

Can I share price quotes with my clients using DiamntX?

Yes. DiamntX lets you create and share professional, branded price cards directly from the app. You can add your company name and logo to every price card before sharing, so clients receive a polished document representing your business rather than a plain screenshot.
