They can be found in portraits of nobles, a sapphire rings on royal personages arms, sapphire earrings at the coronation ceremony. In the world there are many mines were are found this amazing mineral. But commercially it is mined in Sri Lanka, Australia, Burma, Madagascar, China and Thailand. Sapphires found in India are called Kashmir sapphires and have exceptional, so-called "silk" cornflower blue color. For over 130 years, such sapphires are periodically found in mines in Himalayas mountain peaks. Sri Lankan sapphires can boast with the one of the most successful colors of all sapphire stones. Blue minerals can have effect of asterism, showing it when the stone is highlighted. Also in Sri Lanka were extracted orange and yellow sapphires and blue sapphires with a purple tint. The orange color of the sapphire mineral in jewelry industry is called "Padparadscha." Sapphires after cutting are inserted in a variety of metals. You can buy sapphires in gold in combination with other stones. For example, it may be 1 carats sapphire earrings or sapphire beads necklace sapphire beads necklace.

In jewelry with sapphire imitation (so called doublet sapphire) stone from the top is natural, from natural mineral, but the base is a synthetic (usually blue) mineral, it is glued on the top of girdle plane. It may be difficult to recognize in this case, is this sapphire synthetic or not, because jewelry frame not always makes possible to do it "by eye". But if irradiate this stone with shortwave ultraviolet light, you will see a green, or blue and white colored luminescence. To recognize natural sapphire will tint. Colored zones converge in the corner of 120 degrees, sometimes it happens right in the middle of mineral. In synthetic sapphires you will notice sometimes slightly wavy layers, they are parallel to each other. You could even say that they are similar to the lines that we see on a phonograph record.
