I got this piece of gray/pink banded material form rockman69 when I was at his place in Colorado Springs about 4 years ago. It was about 6lbs and shaped like a small shank ham. I cut the shank end off using the big saw at the Salem club about 3 years ago, and the pieces mostly got lost in storage and moving. I can tell you it is in my garage, but not what bucket. Recently I found the shank end and cut it in half, and have taken some slabs off of one of those halves. A few of the bands are softer and I will need to stabalize them or cut around them. I cut one slab at 7mm, but took the other at 4mm because I have a doublet project in mind. I plan to glue the rock to a wood block so I can cut into the edge and get some whole round bands. Not sure how soon I will get that done, but will post pics when I do - or if I find the rest of the rock!

What an interesting rock!!! It sort of reminds me of Polish flint with some of those bands. Actually, the more I look at it the more amazing it is!

Wouldn't that be cool if you could do something with a whole round piece of it so that all of the bands would show. Starting from the center going out to show the total circular design of it!

What is really cool is how it starts with the circular bands in the center & then as they work to the outside you start getting some psychedelic kind of patterns in it! Sorry, I just keep looking at it & am so totally amazed at just naturally happens beneath the exterior of a rock sometimes. Looking at the outside you would never guess it would look like that inside. Guess my enthusiasm is showing!

That is some interesting material Daniel. I hope someone comes along with a name for it. I would like to know also. Can there be a softer material mixed in with flint? Ryholite maybe? I'll be watching with interest

Most flint is from sedimentary host rock, so rhyolite is unlikely. But there is plenty of room for organic inclusions in sedimentary nodules. It is chippy like flint, but does not knap a sharp edge. Donnie's Rocky Treasures: I do plan to get something cut with the whole round bands. I don't think I can get the zig-zagy parts in exxcept maybe in a display piece.

Definitly worthy of a display piece I have some hickorite with similar banding but not that pronounced. Haven't tried any knapping on it so I don't know if it would knap a sharp edge or not

That is a fantastic piece of flint ! i have a similar piece from Australia , the bands of mine are not as close . Cobden flint of Southern Illinois has this circular pattern too.

Ted - the Cobden flint does look close - except for the pink.

yeah, i dont think it is cobden, but was a connection to flint . What i call flint may be called jasper in other parts, but i say they are the same thing.
