Found this on the north western slope of my fire agate spot last winter and I finally got around to cleaning it up and I thought I'd share...
What would the correct name be for this kind of agate by chance if anyone knows, maybe plume or seam agate with druzy/quartz crystals?
Nokta FoRs Gold, a Gold Cube, 2 Keene Sluices and Lord only knows how many pans....not to mention a load of other gear my wife still doesn't know about!
I'm not sure you can call that an agate at all. Usually you will have alternating layer bands of chalcedony for it to be called an agate. But I know the term agate gets used fairly loosely in some circles. Its a nice rock though.
You see banding towards the top below the crystals, almost like it was forming fire agate the clear Chalcedony has a little light blue and white botryoidal banding with inclusions, I'd say agate/chalcedony with vugs and druzy/quartz crystal clusters, some of the crystals resemble cleavelandite, I was told Az isn't known for felsdspar but there's literally two feldspar mines in walking distance from my spot, pegmatites with beryl, lithium, tourmaline, albite to name a few in walking distance as well according to mindat, but I'm sticking with quartz with odd formations. Check out these pair, they are pretty cool....
I may not be very experienced but thats an agate/Chalcedony, actually it a cluster of several agate chalcedony, you can see the backs of them, they form the vugs, a lot of my fire agate is clustered or sandwiched like that making them very hard to carve, you have to pick which fire agate you want to keep and grind off the other fire agate, the white stuff is some kind of crust, some may be kaolinite, if you took the time with a dremel and grinded off all that crust then polished it would be a awesome specimen.
