Charles has been in the diamond industry for over 40 years. He was a director of the CSO, De Beers' selling arm, before deciding to leave De Beers to set up his own diamond businesses in 1995.

He is co-founder of WWW International Diamond Consultants Ltd (WWW) and is engaged in related businesses, mainly with others whose skills are based on the company's expertise in technology, the gathering of detailed market information and a wide range of contacts.

WWW has had a joint venture with the Aboriginal Diamond Group (ADG) through Diamonds International Canada ( DICAN) , and since 1998 has been the Government Diamond Valuator for the Federal Government of Canada and now for the Government of the North West Territories.
