Are your stones raw or are they cut & polished as they would appear if mounted in jewellery pieces? There are tests such as streak & hardness which can be done to raw stones but not to polished stones because these test would damage the polished surface.

There are a number of websites that can be used, such as:

Tests that should be done include:

  • Color
  • Luster
  • Hardness - usually involves testing with the blade of a pocket knife or similar
  • Grain size - the size of mineral grains in the stones. If no mineral grains are obvious the stone may be "glassy"
  • Streak - the color left on a piece of white ceramic when the stone is rubbed on the ceramic.

They bought it from someone who bought it from someone and who knows whether the miner actually knows what they're mining.
