This smooth, solid jasper has such a great texture that some rock sites refer to it as "porceline jasper". Unfortunately, some of the best rocks in the west are simply "tapped out". There is no more to be found. My dad collected this rock over half a century ago. It's the very definition of "old stock" and I know because, as a kid, I was there when my dad dug it up. One thing my dad could do was work hard. We were only there for a day, but my dad dug up some great pieces. He could dig like a backhoe on nitro.
 
I tried to get a fair idea about what my dad's rocks are worth. Lapidary Cenrral has a four pound piece featured for $299. (But it's marked down from $365!)  A shop on Etsy has four pieces that will fit in the palm of your hand -- no weight or size listed -- for $100.
 
This is more than just inflation. My dad collected this rock over half a century ago. I'm sure the jasper location has been visited by a lot of other people who can also dig holes. But check out what is available for yourself. I did, and the results were simply amazing.

If you make something using my dad's rock, send a picture. I love to post pictures of what people have made.
