I apologise if this is in the wrong place of the forum but I wasn''t sure where it should be! Two questions .....
(1) Is it possible to irradiate or HPHT diamonds to become a brown/cognac/champagne or are these mostly natural? My understanding is that these are fairly cheap to buy so why put the diamonds through an expensive process when naturals are readily available. However I read the other day that a brown diamond somebody had bought was irradiated so I''m confused!
(2) Also, why is it difficult to achieve a pink or red diamond using the irradiated/HPHT process but blues/greens can be produced fairly easily?
