I had seen those dodgy green 'chrysoberyls' before. Was actually going to stick a thread on here about them last week, but didnt...

If we are talking barmy internet-based deceptions, I raise you...

I don't even know where to start with this one. But I do know that these pics often pollute the first few pages of Google images for whichever stone I am searching for :evil:

I'm always looking for some chrysoberyl to cut (or re-cut), I noted these huge green gems a few months ago and my guess was exactly Jason's... (there's a lot of synth. quartz with exactly that color) Given the amount of this stuff I can be pretty sure it's not the real thing... :D Also because I always look for flaws/inclusions and those stones are all clean. It could be glass or maybe synth. corundum or spinel, but my guess is quartz. Cheap and very easy to find.

just my two euro-cents. :P

I don't know that it's fair to blame them... they seem to be selling software for jewelers to use in designing pieces. I'd hardly blame THEM that unscrupulous people mis-use the product.

I reproduced that stone in the GemCad using their dimension. (I tried to paste the figure here. But I couldn't.)

Anyways, it gave the volume factor of 0.346. If it is chrysoberyl, then the carat weight should be 37.43 +/-. But it says 24.02 carats. That gives the SG of that stone 2.40+/-. The SG of quartz is 2.65.

I think this is close enough to guess it is quartz. And it is cheap and homogeneous color with many other similar stones. I agree it is synthetic quartz, or maybe glass.

ImageNot the best, but to give you an idea...

Hi

Yes way to go Mitch :smt038 , but amyguy i think you may have gotten the sir part wrong :oops:
Yeah gingerkid i seee the inactive too but look at all the other stuff he sells , lots of big stones , what i like best is the one starting at .50 cents , plus the 10.00 shipping but wait restocking fee and to mail it back you have to do registered mail :shock: , ok so it cost you more money to send it back to them and you get :smt112 nothin :?
