September Sapphires

Sapphire and diamond "Copacabana" ring by Chopard

Welcome to beautiful Sapphire September! (I am a bit biased about this stone because it is my birthstone)
Sapphire is a variety of corundum. It is an oxide mineral and is a 9.0 on the Mohs hardness scale. It is an excellent for any type of jewelry. 
The name Sapphire comes from the Greek word sappheiros meaning ‘blue stone’.  But sapphires are not just blue, they come in every color of the rainbow except red. Red corundum is called Ruby. 
Trace elements such as iron, titanium, chromium, copper, or magnesium can give corundum a blue, yellow, purple, pink, orange, or green color.
