A downloaded copy is free. All you have to do is register as a potential bidder/buyer with Heritage. I can tell you from personal experience that it’s painless. They don’t pester you with undersirable spam and don’t share your information. If you collect, this is a useful and desireable item of literature.

The synthetic diamond scam: “cultured,” “foundry” and other unnatural nomenclature.
