...but we're having fun doing it. Dad had this rock that is covered in shells on the outside so he decided to cut it open to have a look inside. We don't know what the rock type is called, but it was sure neat looking on the inside:  You can see what the outside of the rock looked like, on the top, and what the inside looks like on the bottom:  I cut a piece of Teton Jade the other day and made it pretty thin so you could see what it looked like with a light behind it. Then I took a small piece and just tried rounding it off on one side. You can see what it looked like before and after in the second picture, and the thin piece lit up, first:   It's pretty dark, but you can see the lighter colors on the top edge and bottom edge, and if held up to a light you can see the green come through. Not great work on my part, but it was fun to do. |

Glad to see that you are putting your new found toys to good use right away. This hobby can be so addicting! And the jade looks great by the way. You'll get the hang of the wheels the more stone you put to them.

That rock your dad cut looks like devils toenails. I found quite a bit of it in South Texas. That's a very nice piece!

Both good looking. Thanks for showing.
I've always liked "devil's toenails" , but wonder what that rock is really.

Good job, keep up the curiosity..

I don't know how hard it is (in the US you guys seem to frequently get silica cementation / replacement of things that elsewhere would remain lime). It is a shelly death assemblage (don't let that put you off though!) In the UK, Devils Toenails refers to a specific bivalve, Gryphaea but which tend to occur in mudstone/ shales and really do look the part of their name. Since such fossils are found worldwide (hence their use in stratigraphy) it is possible that you have the same in which case the bioclasts are probably a stack of immature bivalves hit by a catastrophic event ... for them anyway! |

Don't be afraid to come back to it later. |

metalsmith thanks for the explanation. I had googled Devils Toenails but it gave me the Gryphaea --- not the same.

The jade cab is a stunner when back lit. The devils toenail will be interesting to see completed.
