Ruby white gold ring lenses 0.94ct and diamonds
The ruby is the most noble monochristan variety of aluminum oxide (al2OR3), a mineral known as Corindone, strongly allocromatic. It presents hardness 9 on the Mohs scale.
The Mohs scale is an empirical criterion for the evaluation of the hardness of the materials. It takes its name from the German mineralogist Friedrich Mohs, who designed it in 1812. It takes on as a reference the hardness of ten minerals numbered progressively from 1 to 10, such that each one is able to scratch what precedes it and is scratched by what it is follows.
The ruby has a lively red color, due to chromium inclusions, but can take on various shades of this color, ranging from the most lively red, also called "pigeon blood", to the rosé.
The ancient Indians called the ruby Ratnaraj, that is "the king of precious stones".
