An ultra rare collector cabochon of Glendo agate from the 1960s. This one is very feminine, with plumes and fortifications in varying shades of pink, plum and buttercup yellow. It features an incredible tube formation with a pink centre, surrounded by transparent agate, and is polished both sides. A perfect size for an heirloom pendant at 36x23x4mm. From my personal collection and OOAK. Enjoy!
