Ornamental stone - An ornamental stone is a stone used as a decoration. They differ from gemstones in that they are not only used for jewelry.
Artificial gem - Artificial gems are not imitations of real gems, but the actual formation by artificial means of the real precious stone, so that the product is identical, chemically, physically and optically, with the one found in nature. Diamonds, ruby, sapphires and emeralds have been manufactured in labs, which possess very nearly identical chemical and physical characteristics to the genuine article.
Gemma Augustea - Gemma Augustea (Latin, Gem of Augustus) is a low-relief cameo gem cut from a double-layered Arabian onyx stone. It is commonly agreed that the gem cutter who created Gemma Augustea was either Dioscurides or one of his disciples, in 10s — 20s.
Pleochroism - Pleochroism is an optical phenomenon where due to double refraction of light by a colored gem or crystal, the light is divided into two paths which are polarized at a 90° angle to each other. As the divided light follows different paths within the stone and are traveling at different speeds, they may have the result of differential selective absorption, thus when they leave the crystal they have different colors, making the stone seem to be of different colors.

Amethyst is composed of an Eastern name for the stone. Amethyst is composed of an irregular superposition of alternate lamellae of right-handed and left-handed quartz. In consequence of this composite formation, amethyst is apt to lose their colour on the exposed outcrop.

On exposure to heat, amethyst generally becomes yellow, and much of the citrine, cairngorm or yellow quartz of jewelry is said to be derived from the Greek a, "not," and methuskein, "to intoxicate," expressing the old belief that the stone protected its owner from drunkenness.
