Win This Cabochon!

Notice the silver orbs on the far right and center. It's also easy to see the swoops of black rocks.

I've come into some of the most fascinating material, but I can only make a very vague guess of what it is.  

So, I'm offering this cabochon free to the first person (with a U.S. Postal Address) who writes in the Comments section of my blog page www.LapidaryWhisperer.com and tells me where it's from and what the heck is going on in the clear agate. This cab is 25 x 16 x 5 mm and is polished on the back.

It was described to me as "old stock" from somewhere in the western U.S. I'm pretty much convinced that old stock means "I inherited it and have no idea where it's from".  It's obviously a remarkable gold/brown plume, which seems to me is not only an usual color, but might help place where it was collected.

The agate is as clear as glass . . . and then . . . it's full of stuff.  

There are what look like silver orbs at various places in the clear agate. So far, so good. But, when I cut and polish it, there's no sign of the orb bits on the edges. What caused them and where do they go when I polish them?  With many similar features, you'd expect to at least have a small hollow place where the orb hits the edge. Not here! There are, however, some small voids in the plume parts.

Another hint is that when I look at a slab of the material, there are bumps where the agate has a gap before the top lining. They look a bit botryoidal, but not really, if you know what I mean. They're too separated where botryoidal elements sort of pile on each other like a bunch of grapes. It would appear they have something to do with the bubbles, but there's not clear connection.

Notice the clear bumps hiding under the burgundy layer.

Then there's the really cool, almost microscopic black bits.  They swoop around like bits in a river. They also cover some of the plumes.  Notice the cut edge showing the black stuff around the end of a bit of plume. Why do they cling to the plume material but not the silver orbs?

Finally, there are planes on the top half of the clear agate. They remind me of a fried marble (yes, I'm showing my age--and I still have mine!). I really expected that area to crumble off when I shaped and polished it, but it's solid. Again, how and why?

 

My Fried Marble!

WIN THIS CAB!

I'm very curious about this rock, and I really want to know where it is from and what is going on with the clear agate.  I suspect that someone who sees this will show it to a collector friend and ask, "Don't you have a garage full of this stuff?" I hope so.

This is one time that my love of making up stories to go with stones doesn't work. I'm hoping for facts. So if you've ever seen this stuff, let me know. If you're the first one to get the facts to me, I'll send you the cab at the top of the blog post as a thank you!

Until next time,

Your quizzical Lapidary Whisperer,

Donna
