- A doublet (also dublette) is a gem made from two layers in order to save expenses; the lower part of the composite stone is glass or a non-precious stone, the top is the more valuable stone Many different types of doublets have been manufactured (including opal doublets) One common doublet contains a layer of real garnet and a layer of glass A thin, red garnet top is glued to a colored glass bottom A green glass bottom with a red garnet top layer produces an emerald-like stone A diamond is enlarged by cementing it to a crystal base

- A form of gemstone trickery that was devised to allow inexpensive materials to imitate the more valuable gemstones before modern synthetics were available A doublet can take several forms but always involves a fake gemstone produced by gluing together two different materials to form an illusion A very common one in Victorian times was the garnet and glass doublet This involved a red garnet top, glued to a colored glass bottom The refractive properties of a faceted stone are such that the red of the garnet only shows at odd angles, or if the stone is immersed in a special liquid with a high refractive index Thus, for example, a green glass bottom with a garnet top will give the appearance of a fine emerald because the top is a natural gemstone with cut facets, and a few natural imperfections, and the bottom is bright green which reflects throughout the stone The effect is hard to appreciate unless you've seen one

- A counterfeit gem, composed of two pieces of crystal, with a color them, and thus giving the appearance of a naturally colored gem
