Diamond Mining Research and Analysis - Page 4 of 4

The economics of diamond mining, how it works, the leading players involved in the industry, the issues they face, and the diamond value chain.

The impact of consumer demand may seem direct, however, the midstream – the manufacturing section of the diamond industry – often serves as a buffer between miners and consumers.

The following posts provide insights into exactly how this works, the ways miners sell rough diamonds, and the role mining plays in the economies of producing countries.

Rough Diamond Market Report: Subdued Market Ahead of Diwali
