viii Additional Notes on Diamonds, &c.
Doublet or Semi-Stone, p. 218.
A new species of fraud has lately been introduced by some unprincipled persons, which consists in using a plate stone, painted at the back, and then foiled. This is extremely difficult of detection, and the system cannot be too severely reprimanded; for although the practice of foiling stones of pale colour is universal, still, if the pur­chaser be warned that the stone is foiled, he knows what he is buying; but, by means of painting the stone, its natural colour is entirely disguised. A piece of crystal may be, and often is, sold for a sapphire, topaz, ame­thyst, &c.
