How to Separate Diamonds From Kimberlite LEAFtv

Diamonds typically are found embedded in carrot-shaped pipes of volcanic rock called kimberlite, and harvesting the gems means separating them from this rock. Because the ratio of diamonds to kimberlite can be very low, harvesting usually is done on a large scale, and heavy machinery is necessary in the early part of the process.

Kimberlites: Earth’s Diamond Delivery System Gems & Gemology

May 15, 2019· Kimberlite is the name given to a silica-poor and magnesium-rich extrusive igneous rock (e.g., a volcanic rock) that contains major amounts of olivine, often serpentinized. It is a highly variable mixture of melt, minerals crystallizing from the melt, and foreign crystals and rock pieces. Kimberlite may occur in the field as dikes or pipes that crystallize near but below the surface

How We Find Diamond Sources: Kimberlite and Lamproite

This means that total kimberlite occurrences are tens of thousands of hectares of land-mass, compared to 13 billion hectares of land on the planet, of which 7% is located within Archean cratons . Given that less than 1% of kimberlites will yield an economically-viable diamond deposit, finding a viable diamond mine is a daunting task.
