I am looking on the web again for other things that look similar,
they break down along a few lines and are;
1) jaspers, poppy, ocean, iris, eye, fire, others.
2) agates, radiating agates with dendrites or sagenites.
3) rhyolites, birds eye, flower stones, mushroom, others.
4) fosil algae, mary ellen, poppy jaspers, stromatolite.
5) fosil coral, petosky, others.
6) man made materials: Spherulites in a test tube, spherulites in a computer generated image.
7) deep sea continent material, deep ocean stuff only a few pictures.
8) human kidney stones.
9) meteorite, mostly microscopic.
10) bacterial colonies, also mostly microscopic.

the Spherulites in these rocks are not any of these things. Matt B.
