How was it possible that a diamond weighing just over 3025 carats, a gift from South Africa to the English Crown, should be in the Netherlands to be cut and polished?
At this time there was no real diamond manufacturing industry in England, or none with the level of competent cleavers and polishers who could undertake such a giant task.
I J Asscher were asked if they were prepared to manufacture the stone in England. That would have meant that several members of the company would have had to stay in London for a year or maybe longer, apart from that it would have been very difficult to set up a well equipped workshop there. So this offer was declined by the Asschers.
This didn’t leave the English much choice other than having the stone manufactured in Amsterdam.
