Sapphire Gemstone (Hardness of 9.0)
Sapphire comes from Greek word Sappheiros meaning Blue. Sapphire is known as the gem of fidelity, purity, and loyalty and so is a popular choice for engagement rings. However, Sapphire generally comes in blue, but we can also find the stone in pink, yellows, orange, and peach and violet colors. These other color Sapphires are often referred to as fancy Sapphire. Sapphire occurs readily in sizes up to 2 carats, and yet, it is not unusual to see gemstones in sizes of 5 to 15 carats.
Sapphires are found in Kashmir, Burma, Sri Lanka, Madagascar, Thailand, Cambodia, Australia, Tanzania, Kenya, and the United States.
Heating is an important part of the process of polishing sapphires. In order to intensify the color of blue sapphires, they are heated to 2, ooo degrees. Fancy colored sapphires are also often heated to develop the best possible color. Once the right shade is obtained these gems are used in jewels. They are available in mm sizes and far sizes (Usually Below 10 Carats) in shape of Round, Oval, Pear, Heart, Marquies, Trillion, Square, Octogun, Cushion etc.
