The diamond industry has cleaned up its act and is more transparent than ever before, senior executives have claimed, ahead of the launch of a new marketing campaign targeting young consumers.
The global market size of diamond tools has been more than $20 billion. The unit prices of synthetic diamond products are decreasing, but the scale of the industry as a whole is still maintaining high-speed growth.
On the semi-frozen surface of Faraday Lake in Canada's subarctic, two diamond rigs are drilling around the clock. It's spring breakup north of the 63rd parallel, which means the Kennady Diamonds exploration team is running out of time.
These synthetic diamonds are specially designed, which not only keep the characteristics of natural diamond, but also have the ability of filtering electronics. The most important of all is that the cost of synthetic diamond can be controlled.
DiCaprio's tweet last November announcing his "proud" investment in a company "reducing human and environmental toll by sustainably culturing diamonds" alerted the planet to the little-known start-up co-founded in 2012
