I am Matt Boeck and I am a rock hound and mineral enthusiast. I have been the past President for the Palomar Gem and Mineral Society 2008/9 I like Pegmatite minerals. I do beach collecting for Spherulitic rocks and am involved in their study and classification.
What you are seeing are Spherulites; a radiating crystal of amorphous structure that is joined in the center. The rock type is typified by a red brown 'oxblood red' color.
The term Spherulite is not an actual mineral but is a description of a process for more on Spherulites see this link to Wikipedia; http://en.wikipedia.org/wiki/Spherulite_(polymer_physics) it was helpful to me. Other spherulitic rocks (although not minerologically the same) include, Ocean Jasper, the Chrysanthemum stones (rhyolitic) from China, Snow Flake Obsidian, Thomsonite.
- Good collecting- MB

Quartz : SiO₂, Feldspar Group
	San Diego Co., California, USA Spherulite this is a close-up of about 1/4" sq. and there is a photo of the cab here too, I am impressed at the sweeping lamella left and right they seem reciprocal.

Quartz : SiO₂, K Feldspar
	San Diego Co., California, USA Spherulite bulbous bases; See how the first part is so bulbous, Unfortunatly this material does not make real good jewelry, not too showy.

Quartz : SiO₂, Feldspar Group
	San Diego Co., California, USA Spherulite in a clear area; this one is real glassy and the lamalla are radiating well, a cross section revealed that these crystals when cut through showed a hollow core that is 3 sided (roughly) so it is a tube.

Quartz : SiO₂, Alkali Feldspar
	San Diego Co., California, USA This Spherulite is very interesting in that not only is it in a radiating habit from the center but also has concentric rings much like Wavelite and Rhodenite respectivly, the rings apear to stack on top of each other like pancakes! field of view aprox. 1/4" square. Rough rock not a slab or a cab.
