My grandpa was a rock hound, and when he passed, I ended up with a couple decent size nuggets of turquoise, and a small square of what I believe is composite turquoise.

Looking to see if there are any jewelers out there that might be able to make something out of it. Ring, belt buckle, open to ideas.

Makes me wish I paid more attention to the jewelry he made.

check this guy out , my wife really liked his rock videos , she was getting into rock tumbling before she got the cancer

he makes a bunch of stuff and gets deep into the technical of the process.

also you might try the gem shop in Cedarburg WI they have the tumblers and tools to do a lot of the cutting and polishing , it would be worth asking if they make pieces.
or with your skills direct you what you would want for tools to make what you want.
