Champagne diamonds - just another name for brown or cognac or chocolate diamonds?

Champagne diamonds - is it just another name for a brown diamond?
Yes it is. It's a nice name, as is chocolate and cognac. Chocolate diamonds, they're largely called chocolate diamonds in America. We've been calling them champagne and cognac diamonds in Australia. The lighter ones are champagne. The deeper richer colors are cognac.
When the Argyle mine closes at the end of this year, 2020, the main source of brown diamonds will be Russia. The Russian brown diamonds are brownish olive-ish, brown and olive colour. It makes them quite ugly. Not even chocolate coloured. Whereas Argyle diamonds are a really nice honey brown colour. They are slightly towards a yellowish orangish brown diamond, which is a much more attractive colour.
