Currently, the diamond industry is already using X-rays in order to find the coveted gems. The conventional process, however, can detect the diamonds only at the surface of the ore. The diamonds irradiated and activated by X-rays emit light in the optical spectrum. “With particularly pure specimens, this technology does not work because it is precisely these that do not radiate under X-ray light,” explains physicist Jörg Mühlbauer of EZRT. In order to find the gems nonetheless, it has so far been necessary to break up the igneous rock into very small pieces. That consumes large quantities of water and energy. “Moreover, there is also the risk of damaging the larger – and therefore more valuable – diamonds,” says Mühlbauer.

JOHANNESBURG (miningweekly.com) – Improved demand for diamonds coupled with flat supply was making this a good time to be conducting diamond exploration, Aim-listed diamond explorer Botswana Diamonds chairperson John Teeling said in a statement on Monday.
He pointed out that the fundamentals of diamonds were “very strong” and that during the recent “bad years” demand had improved.
“People all over the world believe that a diamond is forever. Prices of rough diamonds confirm this. Though prices are volatile, the trend is good [and] prices have been strong to date in 2014.
“Existing mines are ageing and becoming more expensive to mine, [and] there is little new supply,” Teeling said, adding that the danger to prices posed by a potential flood of diamonds from the Marange fields, in Zimbabwe, had failed to materialise.
