Amethyst is one of the most popular gemstones, and has been considered valuable since ancient times. Its name derives from the Greek “amethystos”, which means “not drunken”, as Amethyst was thought to ward of drunkenness. Amethyst was once highly regarded among the precious gemstones like Ruby and Emerald, but discoveries of huge Amethyst deposits since the 1800′s have made Amethyst fairly inexpensive and very obtainable. Amethyst colours range from light to dark purple, and the transparent deep purple colours are the most highly regarded.

Treatments: Amethyst quartz is typically untreated. Some amethyst stones may be enhanced though heating, but heating of amethyst will reduce colouring agent and result in ‘heated citrine’. Heating can remove unwanted brownish inclusions in some amethysts or lighten the colour of overly dark stones.

Care: Amethyst can be safely cleaned with warm soapy water. Ultrasonic cleaners are usually safe except in the rare instances where a stone is dyed or treated by fracture filling. Steam cleaning is not recommended, and amethyst should not be subjected to heat.
