Title: Williamsite
Post by: Talusman on July 24, 2016, 08:45:47 AM
Cut this yesterday. Very rewarding material to work with - soft (4.5-5) and very solid so goes fast and smooth. Takes an easy polish, too. A local gem variety of antigorite first described at Wood's Chrome Mine (state line pit) in the State Line Chromite district in PA. I believe it's only found in that area and is scarce today as access to the couple of quarries where it is occasionally encountered are closed to collecting.

thats neat looking stuff. too bad its so soft though, like opals i tend to stay away from them nowdays, i always ruin soft stones.

Yes it does need to be protected from harder stones and sand, etc. A good stone for pendants/earrings but not a ring stone. If it was harder it would be Jade, and jade that looks like this is way too expensive! :)

The nice part about softer stones is they work up quick. I cut this freehand in about 20 minutes. No dop and scratches come out so easily.

Wow!  That is just beautiful.  I love the shape of it, too.  It's going to make an excellent pendant stone.   :headbang:

Nice gem. I haven't seen this in a translucent type before so very interesting. There is also an opaque Williamsite from Utah. (I have a lab report) It's lime green with black inclusions that are chromite octahedra.
