Identity HelpBarite?

21st Oct 2019 01:59 UTCLance Tannahill

Specimen is about 2cm x 2cm.
I have had this specimen quite sometime. I originally bought it from a seller who had acquired it from an old collection and he didn't know what it was.  I liked the well defined crystals and it was cheap so I brought it home. I never got around to IDing it, but I recently saw some topaz that looked very similar but this specimen is way too soft (it can be scratched with a screw). Any ideas as to the ID?

Baryte is a good guess. An ideal candidate to determine the SG

It looks like baryte to me, and a nice one at that!   It could be from a number of places, such as the Linwood Mine, Iowa, USA:

I looked up some Linwood barite on ebay and wow it does look similar!  Thanks for the lead.
