New: Large Boulder Slice From Secret Creek, Mayacamas Mts., Sonoma County, California

This is an awesome large fluorescent mineral from a unique location I discovered in Sonoma County in Northern California in 1993 and named Secret Creek.
At that location I discovered a new kind of fluorescent mineral I've never encountered before - a large boulder with beautiful white and red fluorescence inside. This piece is a slice of that boulder. There's a tiny area of pale yellow fluorescence as well. Perhaps that's a hydrocarbon mineral, not sure.

Use Caution When Handling

It's a very hard-to-break mineral which has a few sharp edges that can cut like obsidian can.

Secret Creek is just a tiny creek in a rural area that you'd never expect would have fluorescent minerals.

I'm unable to identify what this mineral is. It appears to be all one mineral in daylight but it fluoresces bluish-white and red. I know that Calcite can do that but Calcite is a relatively soft mineral. This mineral is very hard, not at all like Calcite. It reminds me of some kind of Quartz. I was able to break off slices like this like slicing bread. This piece is fluorescent on both sides.
