I list my rocks individually because I want to send them to people who will appreciate them and I charge enough to ensure that they want them.
 
This smooth, solid jasper has such a great texture that some rock sites refer to it as "porceline jasper". A lot of agate is sometimes called, "duck rock" because it's "full of quacks". That's not a problem with this rock.

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. My best estimate is that Skaggs green jasper goes for more than a dollar an ounce. Waaaaay too much!
 
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.
 
At that price, this piece would go for more than $150.
 
The last picture above is my "Museum Display" specimen. This one is not for sale!  -- Yet.  I'm keeping it, at least for a while. This piece is over 19 pounds. The closest thing I could find on the web was a piece that was about 13 pounds. And the quality wasn't even close to the quality of my rock. The seller wanted about $4,500. Seriously! Just on a basis of weight, not quality, that would make my specimen worth over $6,500. I think it's insanity, but that appears to be where the market is.
 
If you make something using my dad's rock, send a picture. I love to post pictures of what people have made.
