I’m with you on Goodwill doing some good in this world.
People forget that selling cheap items is not their mission. They sell items to fund their nonprofit work. If they are pulling in more revenue then they are more capable of helping people— nothing greedy about it.
i can’t even.
WHAAAAAT??? I guess what I said earlier actually applies…
I’m sorry. If someone spends that much money on that they deserve to lose their money.
But I just saw that shipping is only $3.50 so it’s a bargain after all 
A lot of money for a nice piece of Hubei.
Probably will show up asking for an appraisal here soon
…or black web kingman.
I know, right?! Get ready turquoise peeps …
Or what typically happens is you’ll see it listed back on SGW as the “buyer” doesn’t pay for it. I’ve seen it enough times on pieces I’ve watched out of curiosity to see what they ultimately go for.
Oh wow, people must think that turquoise is really easy to identify. Agreed that this is a nice piece of spider web and the stone is pretty, but not the classic pin-dot look of Lander. The matrix is too “line-y”, if that makes sense. I don’t know how in the world people would trust the word and research of Goodwill employees on what types of stones are present in jewelry; why do people think that they are suddenly an expert because they have access to the internet?
Even when they claim to have supposedly professional tools it still doesn’t mean anything! I have a Christmas tree that I do in sterling silver crosses, and I bought a beautiful sterling Celtic cross from Goodwill. The auction info claimed that the stone that was in the cross was a ruby and had been measured by some jewelers electronic tool. I bought it for the silver, and did not pay ruby prices for, and it turned out that the stone was glass. So much for the bonus of a supposedly verified ruby! Anyway…my point is buyer beware, you’d be a fool to think any random seller online knows what they’re talking about.
Thanks @here4turquoise! Really interesting article, especially the information about the variation in trace minerals and the difference is pressure & temperature of differing mines…who knew. I’ve got to get the last 3rd part of Turquoise in America!
Yes Mike has also written some blogs on the Turquoise in America site about this new testing technique but I think it’s still being developed. I think the ultimate goal is to be able to determine the origin on any piece of turquoise. He has also graded and is selling pieces of turquoise from his personal collection.
My guess is they may have one of those devices (kind of like the diamond testers we used way back when) to check stones - most likely similar to this:
@RedlandMaggie I believe that was the tool named! If it can’t tell the difference between a stone and glass, then it is probably not worth very much as a tool. 
For general use these instruments have their purpose and there are more advanced instruments out there but none are totally accurate. I would start with the standard gemological tools such as a refractometer for most gemstones. IMHO, turquoise is one stone that you won’t have much luck with. The technology isn’t there to differentiate, and due to the low value of turquoise there probably is not much being invested. Too many variables in composition.
This is a good place to start in order to speak intelligently about gemstones:
The diamond testers were great when I was in the biz, we used them constantly when taking in repairs (gotta test those diamonds in front of the customer so there’s no question regarding real and fake), and louped and counted pearls as well - we were pretty thorough 
True @RedlandMaggie . They have the diamond, moissonite, lab grown testers that work well. I had to purchase the new Gemologis tester. It does ID the lab grown diamonds.
