Hey Folks, David V. Horste from Portland, Oregon here. I started lapidary work in 1976 as a 10 year old kid in the rock club back in Jackson, Michigan. I've been a full time lapidary for 22 years.
Here is a piece I call a "Petrified Dinosaur Bone Biopsy". The cells in the dino bone were replaced by clear chalcedony so I sliced it REAL thin, backed it with a big flat mother of pearl bead, and cut and polished it even thinner. The light goes through the cells and bounces off the MOP.
