Paraiba?

I think the other stone will turn out to be the same.
Where did you purchase these gems? Did you buy them as being natural gems?
You could try a Pawnbroker store or Jeweller to see if they have a Presidum gem tester. Hopefully they should do it for free!
A Presidum gem tester has its limits BUT it can easily identify glass.

From a guy who wanted to sell his collection.
Yes, Natural supposed to be.
Pesidium gem tester? i so glass has a specific gravity of like 2.5 i think well the second stone i measured 3.2 on specific gravity i think im gonna send it as soon as i pay the 130 something i owe the gia... Im fuming cant believe its glass so embarrassing.
 
A Presidum reads thermal conductivity. It is a quick and simple test but with limitations. It can’t tell synthetic ie man made gems from the real but it can tell glass from everything else as glass has a very low thermal conductivity.
I wouldn’t waste another $130 on testing the other stone, unless it’s going to something special like natural sapphire (very unlikely wrong colour), the cost of testing will be more than the stones value, even as real blue (irradiated) topaz which it looks like isn’t worth $130.
Can you take them back and get a refund?
 
The second one is slightly magnetic. I bought a bunch of these rocks and they can't all be fake..... I hope
 
What Bron said. I really wouldn’t send any more to GIA due to the expense and the likelihood of similar results. If you like, you can share the other stones you got here. If there are any that people think you should get tested, they will point them out to you. Alternatively, if you could find a GIA-graduate gemologist in your area, you could pay for an hour’s time to look at everything you have.

I know it feels bad. Many, if not most of us, have overpaid or been scammed at the beginning of our journeys with gemstones. My first two gemstone rings were purchased in Bangkok from the infamous Thai gem scammers (thank goodness I only had a college backpacker’s budget back then) and my first jade purchase was not really jade at all. I have a much better collection now :lol:
 
Sorry to hear about your stone. If you have other stones that you know are natural (except opal, amber and such), you make check the heft by bouncing the stone in your hand, glass will feel lighter that most stones.

Thank you
 
I kinda went all out and bought all the ones I could get
 
There’s nothing wrong with any of the crystals / gemstones you bought provided you paid the right price.
The various raw crystals are undoubtably “real” but whether there’s any “gem” material, worthy of the cost of cutting, only a gem cutter can tell you.
Unfortunately aside from eBay there are other web sites that sell all manner of gems as “real” even coming with fancy (but fake) certificates that naive folk buy with misplaced trust. There’s been a few instances of grandma thinking she is making investments for her grandkids to find out too late that they are either man made or so highly processed they are only worth mere cents, not the hundreds of dollars paid.
It’s unlikely but not impossible to stumble across an amazing buying opportunity. I had a once in a lifetime find but it was totally unexpected. I bought a mixed lot from a deceased estate with many little tins rusted shut. I certainly wasn’t expecting to find gemstones inside.
All that said, you can still have a lot of fun with your purchase. You can buy a Loupe if you don’t have one and read up via the internet and try and identify what you have. You might have some zircon, sapphire, topaz in there that a gem (s) can be cut from.
 
So the blue stone came with a number is that like a number for a certificate?
 
Honestly, it could be anything. :-/ You can enter numbers on the GIA website, and you might be able to call AGL if you think it might be from them. Otherwise, I'm not sure.
