Featured Testing for turquoise

Hello everyone.
I'd like some help in identifying turquoise stones on jewelry. Most videos I found on testing stones are lose ones. It gets complicated when you got tiny stones and tightly strung so you can't see the drilled hole very well.
I already used nail polish remover on these and none of them leave a blue or green color on Q tip...might I need to rub harder? Or what's another way I can test these without ripping the necklace apart?
Thx

 

look like turq , to me !

& quite the fashion statement...

 

I did forget the photo of 2nd necklace...both have those little "turquoise" stones.

 

Really? I've never owned real turquoise...how exciting! It would be wonderful if these are natural stones

 

the both look like they were made with the same stones.......and the turquoise...seems to be legit....

mind you.....not likely North American ...

 

Oh...so what area you think they could be from?

 

I'd think ......
"The most common places known for good quality turquoise are Iran (Persia), Egypt, Northwest China, Mexico and the southwestern part of the United States.

these are on a necklace with a Chinese theme.....so...

 

It looks like they could be Chinese turquoise, likely from Hubei province.
Testing can be done with a gem tester.
The cheap ones most of us use only test the hardness on the Mohs scale, which means you have to eliminate the possibility of stones with the same hardness. With turquoise that isn't too difficult, usually the visual is decisive.

I have no reason to believe these stones are dyed, so no colour will come off in a colour test.
Another thing is that turquoise is often treated because it can be quite fragile. A lot of turquoise is impregnated with a synthetic substance, which also 'stabilizes' the colour. Turquoise like that is called stabilized. You can rub as hard as you can, but stabilized turquoise won't give off colour, even if it is dyed.
The stones on the first necklace look stabilized to me. The stones on the second look more natural, but could be a mix of stabilized and natural.

 

Thanks! I really appreciate that
I found some videos that talk about that. Very informative.
Also, when I looked up Chinese turquoise, some images of "carved" turquoise came up that look like that 1 bead on center of 2nd necklace that kinda looks like carved jade.
Could that be turquoise too?

 

It could be, but just to be sure, can you post a photo?

 

Of course!
I'm also curious about the beige/ brown veiny stones...?

 

Difficult to say. I wonder if it is molded, rather than carved.

Could be magnesites.

Ok. Thx.
This is one i found that has been listed as carved turquoise. Of course, it can be inaccurate.
But if I Google images if Chinese carved turquoise many similar pop up.
Either way it's a nice touch

It certainly is, I always like those Shou beads. Shou stands for longevity.

Let's wait for the others, see what they think.

 

The white stones could possibly be white buffalo turquoise. It is mined in Nevada. They use it in native American jewelry in the southwest.

 

White buffalo turquoise is a trade name,the material is magnesite and alumite.

 

I looked this up and it's an interesting topic. I found a few YouTubers that say there is no such thing as white turquoise but I found one that says he had some stones tested in a lab and they are turquoise, but they are different from the buffalo and howlite. I'd have to rewatch it to see where he got the stones from, but I thought it was interesting.
Of course, I have no idea how accurate either one of them is.
Does anyone have a suggested, reliable source where I can learn more about turquoise?
Thanks to all for your responses!!!
