What Are Precious & Semi-Precious Stones?

If you're a jeweller or interested in gemstones, you have probably heard the term precious and semi-precious stones. 

Diamondrubysapphire and emeralds are all classed as precious stones and all other stones are considered semi-precious stones.

This difference was distinguished in ancient times when these stones were viewed as rare and valuable. This traditional view isn't necessarily true today, as many other semi-precious stones can be considered more valuable and rare than those which are precious.
