Agate Cabochon with pin back

I picked up the parcel that includes this piece in Tucson in 1990. Whatever I knew about these cabs is long forgotten. But they photograph well so you can give them your own name… “crazy lace” works pretty good for most of them…
I used to try and look busy at gem shows. That’s how the pin backs got glued on to the backs of these stones. This was over 20 yrs ago. It shouldn’t be a problem to remove the pin if you want.

The total weight including the pin back on AC-1 is 10.93 gm.
Size = 30x39mms (about 1″x1.5″) 6mm deep

The photo is of the piece listed (AC-1) here. The other photo shows the pin on the back of one of the pieces in the parcel, but also shows how the reverse of all the stones are polished (smooth but not high gloss).

Any questions please message me, and I’ll get right back to you.
