Hi; A few months ago while at the Little Ray I found this specimen among the rubble near the stream. Was wondering what the darker material might be? It has a little sparkle to it much like Mica that has turned granular. Thought it was unusual looking so I put it in my bucket. Opinions please.    |

It looks like a beryl or apatite. Have you teted the hardness?

It looks lke a brown apatite to me. I'll say nice find if so! They're elusive little suckers.

Try using a UV light. If it flouresces yellow, it's Apatite. If not, it's probably beryl.

Checked it under both short and long wave and no yellow flourescent.
Sorry, not versed in hardness testing to know what I'm doing.

Apatite has a hardness around 5 and beryl a hardness around 8 so if it's beryl it should be able to leave a clearly defined scratch on a piece of glass, a steel file, or quartz. Apatite shouldn't be able to scratch a steel file or quartz. Looks like it could be golden beryl and the lack of fluorescence in shortwave uv is another very good clue, although apatite doesn't always fluoresce.
