Rough Diamonds of Different Countries Collection
The current assemblage of rough diamonds up for concession includes 23
pieces from 21 current countries (Zaire no longer exists and there are 2 from
the US). Most of the pieces are from the former David New collection. Several of
the pieces are from extremely rare localities. I've tried to go for either best
quality or best crystal shape for diamonds although for some localities, only
the boart were economical. Total mass of the collection is 27.31 carats.
