Stones that are rare and durable are gem stones. "A precious stone is a small, rare, hard stone which has inherited from nature the name of beautiful." The other four characteristics - rarity, hardness, natural origin and beauty together with chemical resistance, all constitute an acceptable definition of a precious stone.
Few precious stones are:- Diamond, Ruby, Emerald and Sapphire.

Semi Precious Stones
All other stones which are sufficiently attractive to be used in jewellery but are not so rare are termed as the semi precious stones.

Such as :- Opal, Jade, Amethyst, Aquamarine, Garnet, Pearls etc.

Synthetic Stones
The inherent difficulty in obtaining synthetic diamonds, at compe- titive prices, is responsible for the development of artificial stones, thus described because they have no counterpart in nature. While there are many different coloured precious stones, and low or modestly priced synthetic forms of the more expensive ones, such as ruby and emerald, have been developed to and on with of the market, there are very few colourless natural precious stones, apart from diamond.

 The two closest to diamond are zircon and colourless corundum, neither of which has outstanding qualities. These are man-made stones which look like real gem.
