I took a week long lapidary class with Michael Boyd at Brooklyn Metal Works the last week in October. Michael is a fabulous teacher and the eleven other people in the class were all incredibly skillful jewelers, so it was a wonderful class.
These are what I cut during the class. There's prehnite (the green), purple garnet, aquamarine, topaz, lemon quartz (the other green), and quartz. I was even able to experiment with carving on two of the quartz pieces.
I'm pretty sure I know what the tinys, lemon quartz, aquamarine and one of the garnets are going to be. The others are mysteries right now.
