Beautiful Brazilian Amethyst Slice C

Here is the story and reasoning behind my price: There is a man in Brazil who cuts and polishes these. It's all he does and now he's teaching his grandson since it's getting harder for him to do. There is a guy here in St. Louis that buys ALL these slices and sells them at the local rock/gem shows that only happens a few times a year. It's not easy to get a hold of these. I've looked online and there are some similar but not the same. Now, I am a rockhound and love all of these and think they are each beautiful and unique(some have better color, some bigger crystals, some look like a lightning storm over the plains) They are polished on the front and rough on the back and edges. C has good size crystals and good color even a few flashes of rainbow. Height: 3.5 inches Length: 3.5 inches Width: .5 inches P.S. Don't leave amethyst in the sunlight, the uv will fade the color.
