I thought of soapstone too and that’s why I decided to test the hardness - it is harder than apatite and a knife blade but softer than orthoclase feldspar.
Sorry I have a bad sinus infection so smelling it is out of the question
I have tried to take some close up pics - I don’t know if they will be useful
A bit of the back-story
I bought a rocks from eBay last year - they came in a nicely labeled divided box - eventually (3 months to arrive - posted 1 month before I got them). The next issue was the painted rocks (yep he painted some of rocks so they would look authentic in the eBay photo - only 6 though - obviously he had run out of those ones). Some of the rocks were correct and some were just lumps of calcite or quartz, some mislabeled and some just in the wrong spot. So I have been going through the whole 156 of them to double check and try to identify whats what - only 28 to go after this one.
The person I bought from was kicked off ebay for a while but I notice he is back selling rocks.
