Sapphire is a blue- light blue variety of corundum, mainly composed of aluminum oxide that has a hardness of 9 on the Mohs scale.

The name comes from the Greek word “sappheiros” and the Hebrew word “sappir” with the meanings of “blue” and “the most beautiful thing” because of its brilliance and majesty.

The largest deposits are found in Australia, Sri Lanka, Burma, Thailand, Cambodia, Vietnam, Madagascar and India.

Considered today a must-have for all women, blue sapphire is often present in the collections of the master goldsmith who sets the stone accompanied by diamonds.

Among the most remembered creations there is certainly Lady Diana’s engagement ring in white gold, 14 diamonds and a central oval 12-carat sapphire.

Sapphires are available in different colors also defined with the term “fancy” due to the presence of some trace elements such as chromium, iron and titanium.

Then there is the star sapphire, recognizable by its needle-like inclusions that predispose a star on the surface of the gem.

The Star of Adam is one of the main discoveries of corundum, the largest blue star sapphire found in Ratnapura, Sri Lanka which boasts a weight of 1404.49 ct.

This stone is often considered a gem with a thousand meanings as it symbolizes loyalty, wisdom and luck for those who travel, while for others a sapphire ring represents the seal of eternal love.
