An expert says that the "painting' of diamonds is a trick known to all dealers. To give yellowish Cape diamonds the appearanee of white Brazilian or Indian diamonds, a man has only to dip them in aniline blue. The operation is so simple that not a few women practise it. They buy cheap diamonds and touch them up in an aniline bath just bef ore wearing them. The appearanee of the doetored diamonds deceives even the expects at th ■ first planee. The layer of color wearp off quickly, however. and the fraud is then evident. The difference between Cape diamonds and the Brazilian or Indian diamonds, which is the basis of the fraud, consists in the greater beauty and clearness of the latter, as well as in their greater durabüity.
