Introduction and Colour

When you hear the word “Sapphire,” one can picture a gorgeous violet-blue gemstone. After all, “Sapphire” in Greek means “blue.” The more saturated its violet-blue color with some hints of velvety transparency, the rarer it is, and more pricey.

It’s also the most sought-after Sapphire by collectors, becoming one of the most expensive gemstones in the world. 

Formation and chemical composition

Sapphire is made up of a variety of corundum and/or aluminum oxide. Its chemical formula involves two parts of aluminum and three parts of oxygen. Its axes are arranged in a hexagonal crystal, which is a crystal of four axes. From these four axes, three are of equal length and intersect at 60 degree angles, while the remaining one is unequal in length to the others and intersects the others at a right angle. 

Fun Fact: A companion corundum of Sapphire is Ruby! If the rubies corundum is pink, then according to the United States Federal Trade Commission, it will be required to sell the stone as a Sapphire.
