If you want to check if a turquoise stone in your possession is natural or a resin, you will have to burn it with a blowpipe.

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.

Step 2: Analyze

Check the result of what you have obtained.

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.
