Chlorastrolites

I believe this specimen contains some chlorastrolite, also known as a Michigan greenstone. I'm not sure what the largest pink mineral is, maybe prehnite? A few of them have specs of native copper included but are hard to view in the photos. I forgot to include a scale for reference, the size is about 2.5 * 2 inches at largest. This is my first greenstone find and I'm just curious if it's worth much. It's one of my favorite specimens so I won't sell it anyways. Thanks in advance!

The value of chlorastrolite is primarily as a lapidary material. You are pretty unlikely to get any cutable pieces out of the specimen.

Very nice pebble, Moe. While the monetary value may be low, the geological stories it tells can be priceless. I confess to being a gravel or pebble hound...I enjoy the stories told in river or lake gravels.
