"Stabilize - To treat Turquoise with plastic or other
substance to heighten its color and durability and increase its
potential to take a polish. Stabilized Turquoise is natural
turquoise to begin with, but it has been artificially enhanced.
The best stabilized stones are difficult to tell from high
grade turquoise, but they are not nearly as valuable and should
not be sold as natural turquoise. An experienced, reputable
dealer is your best bet against misrepresentation."

I have bought and sold natural and enhanced turquoise for a time. I
prefer natural, but will use and sell stabilized.

Zachery - treated Turquoise can not be detected by standard
gemological techniques " I have handled some marketed by Sterling
Turquoise and it was very very nice looking. But …
I have one very large piece of A grade Persian Matrix. It is the best
single piece I have ever seen. As it is from North East Iran,
prospects are very poor for obtaining any more, are poor. Its mounting
still eludes me, but I am thinking Silver / 5% Platinum with 18 K
Yellow Bezel. The mother of all braggers.
I have used the term " not mixing my physics and metaphysics ", but
to me , this is what personal adornment is about .
Professionally, disclosure and integrity are where you start.
