re the "Grape Agate" article. I believe the Min Record had an article Vol.49, No.6 November - December 2018 that identified the material as not an agate/chalcedony but an amethystine quartz. It does look like spheres of radiating crystals in cross section.
Seedless/ pipless. No nucleus.
😆
A very attractive specimen Steve.
Thanks Jeff
Hi Steve,

Thanks Tony. I hadn't seen that article.
