Semi Precious Stone Jewellery

Traditionally, gems classified as precious were those that were both rare and revered.  While market availability or lack therof, was one characteristic of a precious stone, the more important factor was how that stone was used.  Gems that held ceremonial or ecclesiastical value for royal or religious figures were substantially more valuable.  These "cardinal" gems included diamonds, sapphires, rubies, and emeralds. 


Originally, amethysts were also considered precious, but generous deposits of the purple gem found in Brazil made it available and affordable for the public, and it was no longer labeled a precious stone.  Only these five types of gems were ever considered precious, and today, there are more than 130 types of stones that may be considered semi precious gemstones.
