The Genesis of the Diamond - Alpheus F. Williams 1932 - Ernest Benn Limited, London - First Edition 'A truly monumental work of increasing scientific importance, not so much for its information on the diamond and its mining as for its detailed studies of the petrology and mineralogy of kimberlitic pipe-fillings. Such treatment of originally deep-seated mantle-derived rocks was well ahead of its time.

The significance of Williams' studies escaped even himself, and certainly most others. The lukewarm reception accorded the book resulted in an issue of relatively few copies and the book is now difficult to find.' - Capt. John Sinkankas no. 7224.

A fine set in two large volumes illustrated throughout, 31 photographic coloured plates, 306 black & white photographic plates, tables, maps and diagrams.
