Precious vs Semi-Precious

The main difference is that precious stones are traditionally considered rare, luxurious, and inherently more valuable. The precious stones are

  • Diamond
  • Ruby
  • Emerald
  • Sapphire

Semi-precious stones are all other gemstones, which are generally more common and affordable, though some semi-precious stones can be rarer and more valuable than precious ones.
