This Scottish agate has white banding on it throughout. As well as that bit of crazy lacing, there is what looks like a yellow jasper plume on the bottom. It has dots all over which looks like mini eyes or tubes running through it.
This British mineral specimen was found just south of Ayr. It is a piece from 2024. It took a great tumbled shine. If set or drilled it I'd a lovely shape for a pendant.
