The word ruby comes from rubeus, Latin for ‘red’. Fiery red at its most intense, it is the most adored of all red-coloured gemstones.
The ruby is a variety of the mineral corundum. Gem-quality mineral corundum comes in all shades, including blue, yellow or pink. Red-coloured corundum of a certain minimum grade is classified as ruby, while other shades are known as sapphires.
Rubies and sapphires have a hardness of 9.0 on the Mohs scale of mineral hardness, second to diamonds (Mohs scale 10.0) in its hardiness.
Its exquisite beauty, coupled with its innate characteristics, make it a beloved gemstone that is handed down from generation to generation.
The most superior shade of red amongst rubies is known as pigeon blood, thus named for its brightness and colour intensity.
Rubies with rutile inclusions are known as star rubies. When viewed under a single light source, these stones display a celestial six-rayed star across its surface.
