I decided to cut one of my grape agates that was pretty smooth on the outside. Of course I still have a lot of work to do with the dremel, but I'm kind of glad I slabbed it. I think it should turn out nice... Thanks for looking.   |

When I hear grape agate I think of something totally different.
What makes this one?

The one above came with some other grape agates It had less botryoidal features so I wanted to see what I could do with it If you look on the right edge you can see some but not a whole lot Here is a pic of another that traveled with it, this is probably more what you were thinking of  |

Interesting. Sometimes you get turtleback patterns when these are slabbed, but often only where the orbs fuse together near the bases. Yeah, that is what most people are thinking lately. However, all botryoidal agate is "grape agate" (botryoidal, from the Greek, literally means "like a cluster of grapes"). The purple stuff (dyed and undyed) from Indonesia marketed as "Grape Agate" has just been the most prominent new find and written up in jewelry and rock mags. |

I always thought Grape agate was like the one in the link and Mike's was just Botryoidal |

Thanks, I'll have to maybe watch and try for those patterns. I'm just playing around mostly, trying to learn. And I guess I like red grapes.  |

I saw these also when I was trying to learn more about them. I like these too. |

When I hear grape agate I think of something totally different. What makes this one? Good question. The specimen Mike shows comes from a well known deposit in Utah that most Utahn rock hounds refer to as "grape agate" although botryoidal might be a more accurate term. I've seen some that are quite "grapey" enough to pass for grape agate under any definition. |

Whatever you call it, that is a pretty stone.

I learned a couple of things today also, Randy.
That I would rather say grape than botryoidal and that I need to slice one closer to the surface to try to find the turtleback pattern that you're talking about.😃
Seriously, though, thanks for clearing that up and if you happen to have any pics of one you've sliced with that pattern I'd love to see it!

There is some variety in the deposit where this material comes from. If you wander a few hundred yards you may encounter something significantly different. For example one place that's about an acre or two produces agate that's pure white except for a very thin red crust. Go a quarter mile farther and there's almost no white in the centers of the nodules. Almost all of it has the botryoidal features in common. I think a few pieces would make spectacular spheres.
