This appeared on eBay and I bought a piece.
Cuts like butter in my trim saw so I checked hardness.
It is scratched easily by lapis. And it won't scratch lapis.
Therefore hardness estimated at 4-5 MOHs max.
Specific gravity was 2.93.
eBay seller claimed the rock was sold to them as jade.
Then I got an email from the supplier of the eBay seller. Their claim:
"it is a combination of nephite, lizardite and fluorite."
So they believe it is OK for them to call it jade.
