King, in commenting upon the valuation of precious stones during the past three hundred years, mentions two fine rubies which were sold in London recently for enormous sums of money. One of three karats brought $1,500; while another of finer tint, of less than four karats (11 grains), was sold for $5,500, or for $500 a grain, which price is quite equal to Cellini’s estimate made in the year 1560.
