THE WAR YEARS AND AFTER

In fact, in the end, the C.A.S.T. contracts were renewed. On 16 April 1942 Ernest Oppenheimer was writing:
We have come to terms with the Selection people; it is a bit complicated because Otto's purchase has to be deducted from our purchase. To make a long story short (taking into account the amount Otto purchased) Sierra Leone gets a flat 12 per cent (instead of 9—10—11 per cent as at present) with no minimum. The deliveries will be approximately half cuttable and half industrials. This is a useful concession. We have also arranged fixed prices for bort and allied qualities, on the lines of my new arrangements with the Congo companies. If Otto had been more circumspect we might have done better; for all that it is just as well to keep the trade together especially in view of my negotiations with Stallard.12

The imminence of these and other problems led Ernest Oppenheimer to 'philosophize a bit about diamonds generally, not only to clarify my ideas but to place certain experiences on record'. (Ernest Oppen­heimer to Harry Oppenheimer, 21 January 1942.)
The first conclusion to which current events were forcing him was that (letter of the same date):
Our aim must be to retrace one of the worst steps that has ever been taken in the diamond trade, namely the mixing of all production. All diamonds are diamonds and therefore mix them all and sell diamonds. Frames—who knew nothing about diamonds—discovered this false doctrine and forced it on the Syndicate. Every production has its own individuality and no mixing will destroy it. It is the mixing of all sorts of diamonds that has brought our extraordinary assortment. Mixing all diamonds does not lead to bigger trade. On the contrary by selling Wesselton, Bultfontein, Dutoitspan, etc., etc., separately one can always supply the particular class of production most in demand. In the olden days De Beers had a fairly large stock and we could say: Bultfontein is more in demand, give us chiefly B, and then again as fashions will change we asked for Dutoitspan and so on. The assortment has not only become ridiculous by mixing dia­monds but the work is much increased.
These statements are never 100 per cent true. Take Dutoitspan: there are not enough cleavages nor macles to make it worth while to make up made and cleavage series. It was always found that macles from all sources mixed very easily and the same applied to cleavages, but stones never mixed satis­factorily and, after all, that is the bulk of the assortment in value.
