AMETHYST

Amethyst - one of the most sought after gemstones in the world. Traditionally the colour of royalty, amethyst was used to adorn the richest and most powerful monarchs and rulers. Known as the stone of Peace - Third Eye Chakra - February birthstone
 
For me it is the most stunning of crystals, the best stone for stress - helps to calm your mind and heightened anxiety. Helps with better sleep and clearing the mind
 
Cool Facts: Its name derives from the Greek "amethystos", which means "not drunken", as Amethyst in antiquity was thought to ward off drunkenness.
