I'm looking for information on a stone called inpinite. It's a sage green/gray, dull finish.?

I purchased this rock at a local shop and they had no information. I'm wondering if the name is spelled correctly. The shape of the rock is flat and smooth. It reminds me of a river rock.

thank you for your help!

I suspect the name is spelled incorrectly. I have tried several variations of that spelling with no results.
