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!
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.
