Thanks, guys!

Rosemary - Vince cut the stone, but I believe he skipped the 80 grit wheel and started on his 220, which is really well worn and then went up the wheels.  Light touch because it's on the soft side.  He finished it on a felt lap with 50,000 so he wouldn't pull any those mica bits out.  If he did something else different, I'm sure he'll let you know.

Stunning piece.  The stone has almost a fire within it.  Very pretty

Very pretty indeed!  Both the stone and the setting!

Any tips on working lepidolite?  I have some lepidolite rough that is waiting, and would like to know how to best handle the flaky mica material it's made from....  (Thank you!)

One reason that I would be much less inclined to believe that this is 'Polar Jade', is that it is from my dad's collection, which dates from the 60s/70s/80s.  I don't think that  would be the right time frame for Polar jade to be sold to relatively 'normal' rockhounds, even at places like Quartzite, etc.  IIRC, the Polar jade finds were early 2000s...?

Thank you!  The setting was actually one I was making for someone and I managed to mess it up.  So I salvaged the non-wrecked part and the granulation look popped into my head, so I had to do it.  It was a bit tedious, but I really like it a lot (it's for me) and I actually did do the granulation on the bail.  May have over torched it a bit, but it was the first time I have tried it.

Thanks to Jhon for letting me buy some of his sphere off-cuts of the lepidolite!  It's super high grade and gemmy and I love it.  Plus, it's purple.   :icon_sunny:

That's spectacular!  I really like the design and the intricate silver beading.  The granulation beading on the setting is outstanding.  Wish I had the patience to do that...

Robin said it's okay to post a photo of the pendant she just finished.

Thanks to one of the generous sphere-masters here, Robin got some great rough, and I got to help by cutting the cab.

No Jade specialist here but I do have a friend who is a jade dealer and carver.  I purchased some Polar Jade from him and the "flame" in the Polar mine material is a much brighter Green than the surrounding Jade.  I am sure Jade like Agates tend to get sellers and consumers that see something that is similar and throw the popular name on it.  I see moss all the time that gets labeled Horse Canyon even if it is in Nodules which Horse Canyon has never had.

You can get a streak test using any rough ceramic such as cheap dinner plates or white knife sharpener.  The back of a ceramic tile is what I have on my bench.

It took me a while to find a suitable tile.  Tried it:  the unknown left no mark on the ceramic.  So, it could be either garnet or jade, according to the chart I found on-line.
Also tried a scratch test with a known piece of jade.  That was interesting.  The greener areas took no visible scratch, but the gray areas did.  The scratches were not perceptible to touch, but the marks would not rub away... they are indeed scratched into the surface.  So i am assuming that the grayer areas are not jade themselves, but some other material that looks gray when dry and green when wet.
