I went to a yard sale, where a person was selling TONS (literally) of rocks they have collected all over the West Coast, and I found this one among the rocks, and i'm curious if anyone has any idea what this agate/chalcedony may be? or where it may be from? its quite odd, but quite pretty.


If it helps any (doubt it will ) I got this specimen from a collector based out of South Western Oregon.

it's either holley or ellensburg.

That appears to be more waxy looking than agate/chalcedony. It looks more like the blue opal from Oregon. Is there any with a brown outer rind on it?

To me it sure looks like Oregon blue agate. Although pictures can be deceiving, the color is closer to Ellensburg agate. In any case it is a nice blue agate.

Duh, Ellensburg is in Washington. Here is some Ice Blue Agate from the Polka Dot Agate mine near Madras.

Folks,

None of those appear to be "Agate" (A distinctly banded variety of Chalcedony). Banded being the discriptive word for this form of Chalcedony from the Quartz family of minerals. They all appear to be fine examples of Chalcedony, due to their silky fine grained silica looks. Of course they could have been broken or cut from the "Eye" of an Agate. But then they would be Chalcedony, without their banded components.

Joe I didn't coin those names. That is what they are called around these parts. Chalcedony as a term is just too broad to be very helpful in trying to help distinguish between the many many varieties of chalcedony found around here. Many of the rocks we call agate actually do have examples that have bands etc. and fit your definition, and others do not, and they all come from the same location. Only calling the banded ones agates and the others chalcedony just causes confusion. Personally I prefer the broad use of terms such as agate, jasper, rhyolite, etc. to help distinguish between the many varieties of chalcedony found where I hunt for such material.

yeah, scientifically, there is no such word as agate used for identifiacation. all forms of agate, jasper, opal, and flint fall into the one classification of chalcedony. holley and ellensburg have both commonly been called "agate" for as long as i know of, as are all other forms of chalcedony, except for the chalcedony roses.

Could you get a better view of the side of the piece. to me it looks like Blue lace agate from Africa

bob, i cut alot of the namibian blue lace and because of the back bottom picture it looks like not. it still has the texture of the basalt it came out of and the blue lace is sandwiched between two layers of quartz or quartz after calcite. what you're seeing is most likely the botryoidal chalcedony layering up toward the druzy. christopher, what color is it when held up to the sun?

its grey/yellow when held to the light, and I have a Namibian as well and it glows blue/white in the light, so the latter isn't namibian.

btw Richard, you're one smart cookie, kudos.

the grey/yellow rules out ellensburg, although it could have been found nearby at red top. people are pretty exclusive about what is called ellensburg. honestly though, i've seen buckets of holley that look just like that. if i'm correct, you're in the eugene area. you might want to take it over to jim nelson's rock shop, "nelson the rocky feller" (assuming he's still alive, i haven't been over there for 2 years). he's really nice and knows quite a bit, although he almost strictly sells foreign material. merle's rock shop on hwy 34 outside of corvallis also could help, although merle died a few years ago. his son and grandson run it on the weekends and might be able to help, but merle was the one who really knew it all. i inherited a large collection that came from him. my grandfather bought him out in the 60's when he was goinjg through divorce and had to liquidate his collection. i have boxes and boxes of material that i haven't identified yet. i usually learn about one per week. the detective work is alot of fun.

I would not rule out Mt. Airy Blue from Nevada.

The first 4 photos is a single piece of Holley Blue from ( Wt. 58 Lbs. ) came out in two pieces, Scott Mt. South of Lebanon,Oregon.

And The the last 3 photos are Ames Cr. Blue agate from Sweethome, Oregon.

Most of the Ames cr. agate is about 5/8" thick.

And the edge looks just like South African, And the color.

The wall that the material was dug from was Blasted in 1974. People had under cut it to far in.

Thank you guys for all your help. I'm only 23 and have severe health problems and I don't think I can hold out much longer, so
I've been travelling Oregon on the budget I have left, looking for the perfect stone to make me feel as though my quest is completed. Rocks are the one therapy that have actually helped. I really appreciate all your help.

Chris, I can't think of a more inspiring pursuit then hunting for the infinitely beautiful gems and rocks in such awe inspiring locations that have been given us by forces we do not understand. I hope they lift your spirit above your day to day struggles and bring peace to your epic journey.

Chris,

Your pursuit should be a lesson to all of us to use whatever time we have on Earth to seek the "perfect stone" with honor and integrity.

Here's hoping you not only hang on, but find a way to beat your health problems.

God bless.

Mike

Thank you guys for being so caring, it honestly made me cry, and I don't do that too much. I felt lucky yesterday, as I found a 50 pound slab of high quality Jasper in a creek, in the mountains. I know Jasper isn't that great, but it made me happy never-the-less. I found it while searching for a "well-known" Carnelian dig site, but never found the dig site. People around here like to keep their mouths closed on this site, and ive half destroyed my car looking for it. Its funny, the small and beautiful things you find when trying to find something much bigger.

if you'd like help finding chandler mt., let me know. i'm pretty good at finding old digs, assuming it's not behind a locked gate up ames creek. i'm just assuming this is what you're looking for.
