High voltage pulses break down kimberlite - Diamonds intact

An Edmonton high school student is being credited with a discovery in the world of diamond mining.
Hamdi Ali is only 17-years-old. Together with her mentor, she discovered a new way of removing diamonds from rocks.

They started by x-raying a piece of rock to see the diamonds inside. After that, they used two methods to extract the diamonds from the rocks. They cut one half of the rock with the industry standard mechanical vibrating plates. The diamonds inside were destroyed. For the other half, Ali used a device that shot high voltage pulses to break down the rock. She then found 10 intact diamonds. Using a mechanical crusher damages a significant number of diamonds and decreases diamond yield.
