Originally, the first five precious gems were diamonds (of course), emeralds, rubies, sapphires and amethysts (which were later reclassified because they were too common to be considered precious after becoming more widely available). Nowadays, if one refers to a precious gem, it is assumed to be one of the four previously mentioned. Both are considered very exotic stones. Sapphires, though most commonly thought of as a deep blue stone, actually come in a variety of colors that are very valuable, with prices set at a premium.

Hardness also determines the value of a stone and normally greater than 7 hardness rating on a scale of 10 is considered as superior. Other characteristics of high quality stones are durability, transparency, and brilliance. Some stones are heat treated to change their natural color and this process decreases their value.
Emerald gemstones are also said to give its wearer the gift of good eyesight and intellect. Some also say that emerald gems can be used to treat poison. It can also be used as treatment for dysentery as it has laxative properties.
