Investment Diamond Exchange

Welcome to the WDI Investment Diamond Exchange*

The WDI Investment Diamond Exchange is, we believe, the first open diamond exchange to enable private investors to buy and sell GIA-certified investment-grade diamonds, without inflated retail mark-up, with minimal fees and total transparency. WDI does not include in our listed stones any diamonds that include a tint, hue or overtone.

The prices listed (in US$) are wholesale prices including 3% broker commission. They can only be purchased through an Authorized WDI Broker. Investment diamonds can also be re-sold on this Exchange.

You can log in as a Guest to see the range of diamonds currently available for investment, but you can only see their prices if you are a broker or have been given a password.
