Unfortunately coated diamonds (not irradiated/HPHT) are now being sold in the UK. I have seen blue, green, yellow and pink. They appear to be coated all over and not just the pavillion.
However, I haven''t seen them in a brown/cognac colour. My understanding was that brown/cognac/champagne (sorry to use these terms) are normally speaking natural. So, can brown diamonds be achieved by:
(a) coating or
(b) irradiation/HPHT to achieve this colour?
