Following the vote RapNet announced it would not list synthetic diamonds on its trading network and Rapaport USA announced it would not publish a price list for synthetic diamonds.

In a keynote address at the Las Vegas JCK jewelry show Martin Rapaport called on the diamond industry to support a $1 billion marketing campaign for natural diamond engagement rings. He also called on those selling synthetic diamonds to make full disclosure regarding the inability of synthetic diamonds to store value as they can be produced in unlimited quantities.

A video of the presentation is available on the Rapaport Facebook Page. In addition, an important article entitled “Synthetic Ethics” is available and highly recommended.
