Jewels, gemstones or gems, sometimes called valuable stones, are pieces of mineral that are usually used for making jewelry or other ornaments after cutting and polishing. Almost all of the precious stones are thought to be hard materials, but some soft minerals are also used as jewellery because of their luster. There are many thousands of known minerals existing in nature, but only about 100 are regarded as true gem or jewel minerals. There are only about a dozen or so gems that are essentially valuable enough to be considered significant gemstones in the world market. A mineral is considered as a valuable precious stone if it is pretty, hard and sturdy. The fantastic thing about a gem is measured re its clarity, brilliancy and color. The valuation of the precious stone is dependent on its rareness, purity, lucidity, beauty, cut and size of the stone.
Gems can exist in different colors depending upon the atomic structure of the stone. While the natural beauty of the gemstone can be reinforced by cutting and polishing in the correct way. There are different types and treatments to improve the color and clearness of a stone. The heating process is the commonest way used to improve the lucidity and colour of stones. There are some treatments that are widely used where the consequent stone is stable. While there are other treatments that aren't ordinarily accepted as the ensuing colours are usually unsteady and may, sadly, go back to its original color after a little time.
Precious stones are traditionally classified in every period of time from the Ancient Greeks to the modern day and in each culture of life. In the modern period, gemstones are divided into precious and semi-precious stones. Diamonds, rubies, sapphires and emeralds are thought to be dear stones and every other stone are assumed semi-precious. In some classifications, stones are characterized regarding their color, transparency, toughness and translucency. Gemstones are also split into different groups, species and varieties. For instance, ruby is the red range of species corundum while any other colour of corundum is considered sapphire. A person who identifies technical gemstone traits (chemical composition, crystal system, optical properties, habit, healing ability, and so on.), is referred to as a gemologist.
Valuable stones are found on the surface of the earth, as well as, in the seas. The 9 most critical gems found between land and sea are rubies, pearls, red corals, green emeralds, yellow sapphires, diamonds, blue sapphires, hessonites and cat's eyes.
Man-made gemstones that are created in labs are called synthetic or man-made precious stones. Man-made diamonds are often made in large quantities as industrial abrasives and are available in multiple carats. Artificial corundum including ruby and sapphire are very common, but only cost a small part of the natural stone. But whether the stone is natural or made in a lab, they always have the same traits.
