Sapphire comes in 2 varieties: natural saphire and man-made sapphire. Natural saphire must be mined… naturally. When people bethink sapphires, they usually think about blue sapphires. However , Blue sapphire is the outcome of titanium and iron in the stone’s crystal lattice. Occasionally, the trace elements do not completely osmosis the stone, which explains why it reveal itself with grey-toned colours. Because of this, it’s a general practice to heat natural saphire in order to ‘cook out’ the errant colours and bring the sapphire back to its original blue color.
Natural saphire comes in a variety of colors. Sapphires that are not blue are referred to collectively as natural saphire. Purple sapphires as well as other coloured natural saphire can be found in Madagascar, Thailand, Burma, Sri Lanka, and Australia to cite a couple regions. Heating natural saphires may add to their worth by raising color and lucidity. It is determined that over 90-95% of the sapphires in the market today are heat-treated.
The most heavy source of natural saphire is from Australia and Madagascar, although different kinds can be found in deposits all around the globe. The natural sapphire crystal structure is hexagon with triangle terminations which are often flat. Sapphire may also be disposed in the gemological laboratories. The created stone is just as attractive as the natural saphire, it also has the same hardness and durability. However , the value of a natural saphire is higher than the treated sapphire. Blue natural saphire is a blessing for the jewelers as its always in style and is valuable.
You should only buy natural saphire from a credible dealer who knows what they’re selling and who will disclose any treatments that have been performed on the gemstones. High quality, natural saphire are extraordinarily rare and expensive and should be accompanied by a certificate of authenticity.
