“Research is creating new knowledge.”

Neil Armstrong

We believe in combining practical solutions with sound academic underpinning. 

Rocks International keeps a daily track on what's happening in the diamond and jewelry industry. Doing so, we have gathered substantial data, research and news on topics such as diamond vs. investment, macro-studies on the diamond industry, pricing forecasts and investments in listed and unlisted mining companies.

With respect to our diamond investment projects, Rocks International and Partners are working with the PhD Department of the Tilburg University in the Netherlands, under the leadership of Prof. Dr. Luc Renneboog.
