Not sure what this beauty is

I was told this was Lapis...I know it is not. Is it possibly Lazurite? It is a lighter blue and when I shine a light through it...it is not opaque but has a slight translucence with green in it...there is no cleavage where the blue and cream meet either...perfectly smooth on the front and back...don't know what it is ; ) What you see on the backside are the scratch marks from the sanding of the stone

Definitely NOT lapis or lazurite. Lapis is a more intense blue with calcite and pyrite inclusions and looks very different from this. Whatever it is, it looks interesting. Do you know anything about its origination?

I know nothing about it's origin...however today I took it to a lapidarian here in town and she looked at it with her lights and magnifiers and was stumped as well...she said her best bets (unable to be certain) were gem silica or fluorite, she said fluorite isn't usually put into settings with the matrix but you couldn't use that to identify ; ) and one way to differentiate between these two would be to see if quartz scratched it, so I took a quartz point to the back of it...quartz does scratch this stone and gem silica wouldn't so...maybe fluorite but again she was truly stumped and couldn't say for sure.

Doesn't look like fluorite either, and she is correct that it is usually not put into a jewelry setting - it is too soft and prone to chipping from strong cleavage. Its possible that it is fused glass. If you can do a hardness test and if it fits 5.5 that is a likely scenario.

How does one do a hardness test?

So...hardness between 3 and 4...pretty soft ; ) I cannot scratch it with my fingernail...a penny won't scratch it but will sheer it to a shine and fluorite scratches it ; ) so...

Had another lady today looking at it suggest a blue septarian...??? maybe, never heard of it being blue but calcite does come in blue...

Blue imperial jasper? I purchase this stone at a bead store, and that is what I was told.

If you shine a light through your Imperial Jasper...does it become all green like this one does? Curious ; ) Jasper is harder than this stone tests at so I'm guessing it's not but after looking it up, it does indeed look quite like it ; )
