The large piece in the foreground is my favorite. I would love to have it in a setting as a pendant. It measures about 3” across and is a thin piece with cutting marks from a saw on the backside. The design gave me one of those Wow! moments when I took it out of the box. I believe it is Hubei Turquoise.
The pendant in the middle belongs to @harmonart, I swiped it from another post where it matched a ring I had.
