Arizona Seven Springs Onyx Rock Lapidary

This is a large piece of Seven Springs Onyx. Measures 20 x 10 x 8 roughly and weighs almost 100 lbs. my father was a rock hound and into lapidary and this was a piece he asked me to keep but has since passed away. You can see it is very colorful and would make some excellent jewelry or display pieces cut and polished. If you have a better idea of what it is than I was told and can prove it I am open to correcting the post. I don’t want to sell it as something it isn’t. Price is negotiable. Would prefer you come and look at it in East Mesa as it is so heavy to transport.
