Natural sapphire is a kind of corundum mineral. Real stones of this type have been waiting for thousands of years in natural conditions, in the bowels of the earth, for their appearance.
In ancient Rome, it was worn only by the priests of the temple of the god Jupiter; later, for Europeans, it became a symbol of sincerity and modesty. In the East, sapphire personified wisdom and was associated with achievements and victory. In India, it was used to decorate priests' clothes, and even in Ancient Egypt, the stone left its mark - thanks to Queen Cleopatra.
Classic shades are blue and light blue. But genuine sapphires may also be of almost any color. There are also yellow and green, pink and purple, black, colorless (white), as well as polychrome variations. Stones that are not blue are called fancy sapphires.
Place of mining:
The richest sapphire placers are located in Southeast Asia (Thailand, Myanmar (formerly Burma), Madagaskar, Sri-Lanka, Tanzania, Australia, and the United States.
Sapphires are usually not very big. In a faceted form, they rarely exceed 5 carats. Large stones often do not have the best quality characteristics. They can be processed into a cabochon shape. It should be borne in mind that the larger the genuine sapphire, the higher it's cost per carat.
Stones with an asterism effect are considered especially unique. It is a phenomenon in which a pattern in the form of a hexagonal star appears on the stones under certain lighting conditions. The phenomenon can appear when a suitable sapphire is cut en cabochon i.e., shaped and polished (not faceted).
How to distinguish a sapphire from a fake
If true sapphires can be found in the depths of the Earth, artificial ones are created in the laboratory in just a month or two, depending on the size of the future mineral. The resulting gems are chemically the same as natural sapphires, so they cannot be called fake. However, these sapphires have no investment value. There are also fakes made of glass and other less valuable stones. Therefore, it is necessary to know how to distinguish a real sapphire from a fake one when buying jewelry like a ring.
You can distinguish between fake, synthetics and natural stone using:
Asterism effect. The easiest way to discover the authenticity of this gem with the effect of asterism, which is rarely fake quality. When the natural stone rotates, the star shape will change its position, but it will remain in place in a fake.
Monobromnaphthalene. The specialist needs to immerse the stone in a special liquid called monobromnaphthalene. He can easily see the special stripes inside the crystal by viewing a mineral through a transparent container with monobromonaphthalene. If they are straight, the stone is real. If curved, it is fake or synthetic.
With a magnifying glass. Least of all foreign bodies inside artificial stones. In addition, synthetics will be given out by gas bubbles inside, which can be grouped or located separately. Also, inspect the stone's surface for the presence of glues. There should not be even stripes on it, otherwise in front of you is a doublet or triplet - a sapphire formed by gluing two or three parts of the stone together.
Refractometer. This device measures the degree of refraction of light in stones. For sapphires, the refractive index is 1.762 - 1.778. A deviation of even 0.1 will indicate that it is not a sapphire in front of you.
