Introduction: Check If a Turquoise Stone Is Natural

This test can be made if you have a rough stone or several stones from the same lot.
Step 1: Burn Them
Set the stones you want to test in a crucible.
Burn them with a blow pipe during 2 minutes.

If you have ashes then you had a resin type of stones.
If you still have stones that turned white, then you have tested natural turquoise stone.
