Mineralogical characteristics
Sapphire belongs to the corundum family, together with ruby. Both gems are crystalline varieties of aluminum oxide and are among the most appreciated gemstones in the world, together with diamond and emerald. The name sapphire comes from the Greek “sappheiros”, traditionally related to the color blue.
With a hardness of 9 on the Mohs scale, sapphire is one of the most resistant known minerals, surpassed only by diamond. This great hardness, together with its vitreous luster and transparency, makes it a highly valued gem in high-quality jewelry.
Although blue sapphire is the most famous variety, specimens exist in numerous colors such as yellow, pink, green, violet, brown or even colorless. These tones depend on the chemical elements present during its formation. Iron and titanium produce blue tones, while chromium generates pinkish or reddish nuances.
Sapphire also stands out for its pleochroism, an optical phenomenon that allows different tones to be appreciated depending on the angle from which the gem is observed. It forms in pegmatites, metamorphic rocks, gneiss, marbles and alluvial deposits, where it may appear as highly pure pebbles.
