Questions
Is stabilised turquoise fake?
Stabilised turquoise is turquoise that has been treated. A dyed different mineral is an imitation. These are different questions.
Can matrix identify the mine?
Not reliably from a photo.
Should I scratch, heat or apply acid to test it?
No. Destructive home tests can damage the item and still mislead. Record what you can see and seek qualified testing when the answer matters.
