Thank you so much dogteam!
To be honest this is a complete new territory to me and I have been puzzled by this 'greenstone'denomination. If I read correctly, it is not really Jade, it is not granite, but what is it then.
I also would be very grateful if I got an opinion about my beads, their origin...
If it does not work out, don't worry. I appreciate the effort!
Thanks again.
