The name sapphire probably derives from the Greek “sappheiros” (blue) or from the Hebrew “sappir” (more beautiful thing). It was once thought that owning sapphires was a sign of goodness, magnanimity, fidelity and command.
It is also said that sapphire also had therapeutic powers (visual and intestinal apparatus, stop bleeding, healing from inflammation, against scorpion stings).
Sapphire deposits are in Burma, Thailand, Sry Lanka, Kashmir, Montana, Australia. The color of the sapphire is due to traces of iron and titanium, and can vary from a light blue to a darker blue with, sometimes, some greenish hues.
A ray of light that penetrates a stone such as ruby ​​or sapphire splits into two rays. This phenomenon is called birefringence or double refraction and allows any object observed through the crystal to appear slightly doubled. The luster of ruby ​​and sapphire is glassy, ​​but can sometimes tend towards adamantine. The dispersion value is decidedly modest compared to that of the diamond, and therefore the beauty of the corundum does not lie in the flashes of colors, as in the diamond, but only in the nuances of color.
