The 800 Carat, Nipissing Yellow Diamond

Learn the history of the Nipissing Diamond, and how RJK Explorations is working to uncover its source.

Cobalt, Ontario is a very historic mining town which was built on silver. In fact it became the Silver Capital of Canada after it produced over 460 million ounces from over 100 mines since the initial discovery in 1903.

Oddly enough the same year the Nipissing yellow diamond was discovered west of lake Temiskaming. Unfortunately, the diamond discovery went somewhat under the radar… until now!

RJK Exploration is actively working to write their own story about the famed yellow diamond and we are happy to be helping them tell their story.
