Stone Quiz

Can anyone guess what this stone is and it's origin ?

 

Are they the same mineral in the same light?

 

Good question!!!
Was thinking alexandrite cat's eye... But also Czech glass

 

Difficult to say from one only pic...

 

I thought glass right off.

 

Is the left one a smoky quartz?

 

Just noticed that you asked what "stone", singular.
So I take it the two are of the same origin.

Therefore I take back the smoky quartz suggestion.
The green looks like lucite.

I'm going to guess that these are manufactured and not real "stones"

Can't wait to see how wrong and way off base I am.

 

Me too!

 

Lucite? Could be. All I know is stone they ain't. There's one with a similar look called "sheen obsidian" but it's dark gray to black and doesn't come dyed other colors to my knowledge. It's also not worth much more than glass.

 

I'm really bothered by the use of the word "stone"...

If you had quizzed on "cabochon", my answer would have been "dyed mother of pearl".

But I'm too conflicted to use that answer here.

 

Are they Andesine feldspars?

 

Wish the pictures enlarged so we could see them little better.

 

Too much noise in the photo to know what they really look like:



A bit too vivid for andalusite cat's eyes.

 

Holly's cat likes them. Must be Cat's Eyes

 

Actually, there is too much light reflection to really tell anything.

It is a man made "stone" made of various minerals and at one time it was referred to as synthetic jade and known a Victoria/Iimori stone.It is hard to photograph as is opal,examples here....... https://www.google.com/search?q=imo...ntriAhXRqZ4KHZvgBEYQ_AUIECgB&biw=1521&bih=891

Ah! For sure, that was a mysterious material!
I'm puzzled by the definition of it in jjlrocksandminerals link:

This is not an imitation or synthetic but is a
reconstructed natural stone.


To me, it is not a "natural stone" as it was man made

Thanks hollyblue for showing

 

I had the same issue with the first link. The second link said "Those minerals were fused together by heating them to intensely high temperatures to form a molten magma"

 

Found a more up to date reference for Victoria stone,it stated the material is now considered lead glass........... https://www.snobappealjewelry.com/b...-new-research-and-victoria-stone-color-chart/
