In 1776, fourteen hundred and seventy-one diamonds belonging to the French crown were sold, and the money thus obtained was used in re-cutting the remainder besides adding sundry other jewels to the Regalia. In February, 1788, the Antwerp Gazette makes known to the world that there had just been completed in that city a work of great magnitude. This was the re-cutting into brilliants of all the rose-diamonds belonging to the King of France. The reader will remember that "roses" are diamonds covered over with facets, such as the Orloff, while the brilliant properly so-called is a double pyramid, a highly refracting figure, of which the Regent and the Koh-i-nûr are examples. Diamond cutting was a lost art in France; hence the reason of sending the gems to Antwerp. Cardinal Mazarin, a great diamond fancier, had endeavored to stimulate diamond-cutting in Paris. He had imported workmen and wheels and then had caused his own stones and those of the king to be cut. When this was done, and further diamonds not being forthcoming, in order to still encourage his pet industry he had the same stones cut a second time! Such expensive encouragement of the diamond-cutting trade has probably never been heard of before or since. The Antwerp artists having accomplished their task to the satisfaction of Louis XVI., "he rewarded with presents, magnificent and really worthy of a King of France, all those who had a hand in it." The Blue Diamond came forth from the hands of the cutter an irregularly-shaped brilliant of a drop form weighing sixty-seven and one half carats. In 1791, it was entered in the inventory of the Crown Jewels, which was drawn up by order of the Constituent Assembly, at the high valuation of six hundred thousand dollars. It will be thus seen that it had enormously increased in value since its "rough" days, for then the Blue Diamond as well as all the other diamonds and precious stuffs were bought from Tavernier for that precise amount.
