Many UK jewellers have conceded they have no real policy on sourcing diamonds...almost two years after the diamond industry agreed to a self-regulation system to prevent the trade in diamonds from regions of conflict, many UK jewellers are unable to assure customers that the diamonds they are buying have not been sourced from conflict regions...Leading British jewellery retailers Asprey [part of A&G Group], Theo Fennell and Debenhams did not respond to letters requesting written information about company policy on conflict diamonds. In the US, Costco Wholesale Corporation, TJ Maxx [part of TJX] and Kmart did not respond.
