Stones that can change human behavior
Jewels, precious stones or gems, often called treasured stones, are pieces of mineral that are typically utilised for making jewellery or other ornaments after cutting and polishing. Most of the gemstones are regarded as hard materials, but some soft minerals are also used as jewelry due to their luster. There are thousands of known minerals existing in nature, but only about a hundred are considered as true gem or jewel minerals. There are only about 12 or so gems that are actually valuable enough to be considered essential gems in the world market. A mineral is thought of as a valuable gem if it is attractive, hard and durable. The great thing about a gem is measured by its clearness, luster and colour. The market value of the gem relies on its rarity, pureness, clarity, beauty, cut and size of the stone.
Gemstones can exist in different colours relying on the atomic structure of the stone. While the natural wonder of the precious stone can be augmented by cutting and polishing in the proper way. There are numerous types and treatments to enhance the colour and clarity of a stone. The heating process is the most typical way used to enhance the clarity and color of stones. There are some treatments that are commonly used where the resultant stone is stable. While there are more treatments that are not commonly accepted because the resulting colors are typically unstable and may, unfortunately, come back to its original colour after some time.
Gems are historically classified in each time period from the Traditional Greeks to the current day and in every culture of life. In the modern period, precious stones are split into precious and semi-precious stones. Diamonds, rubies, sapphires and emeralds are considered valuable stones and all other stones are presumed semi-precious. In some classifications, stones are characterized with regard to their colour, transparency, hardness and translucency. Gems are also classified into different groups, species and types. As an example, ruby is the red variety of species corundum while any other color of corundum is considered sapphire. An individual who identifies technical gem characteristics (chemical composition, crystal system, optical properties, habit, healing capability, for example.), is called 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 precious stones that are manufactured in research labs are called artificial or synthesised gemstones. Synthetic diamonds are typically manufactured in large amounts as industrialise abrasives and can be obtained in multiple carats. Synthetic corundum including ruby and sapphire are exceedingly commonplace, but only cost a fraction of the natural stone. But whether the stone is natural or manufactured in a lab, they mostly have the same characteristics.
