DESCRIPTION

Sapphire is one of the four precious stones, it is part of the corundum family.Located at 9/10 on the Mohs scale and has a density between 3.97 to 4.05. Sapphire is the third the most resistant mineral on our planet after moissanite and the famous diamond! This concretely means that no stone can scratch it apart from itself and its two predecessors.

One of the great characteristics of corundum is its wide variety of colors. Ranging from light blue to a darker blue, sapphire has a very wide range of shades. The most famous being of course the blue and the red (for the ruby).

Its natural composition being colorless, it is paradoxically the presence of impurities that gives a sapphire its color. For blue it is a mixture of iron and titanium oxide that will give this famous color. Chromium oxide will make a sapphire pink, for example, but it can be found in different colors such as green, yellow or orange.
