found a couple speciman of what I believe are dark green schrol crystal clusters. Found in Bancroft, ontario. Looking for more information.

Please take quality images. These are far too blurry to make judgments.

But, if I can see correctly through the fuzzy images, I'd say diopside. But without good images, you'll not get any quality answers...

If I were mushroom picking in the southwest, and ate the wrong type, and then waited for a bit, these would look quite close to a pyroxene crystal cluster;) Try taking photos of the piece or any future pieces with it on a table without any motion, or buy a cheap $9.99 tripod which will work wonders for you.

Welcome to Mindat, Eric.

Agree, the photos need to be much better quality to hazard any guesses.

...and please see the Mineral Identification post pre-req list.

It is often difficult to impossible to make an ID from just a picture -- I have a hard enough time with the rock in my hand.

Cheers,
D.

Hey thanks guys sorry I will upload a few more pics.

If it's dark green, don't think it would be schorl (but without an analysis....). And even tho the photos are blurry, they don't ring a bell as to schorl. Will wait for better photos to see if I be a dummy.....

They look like me to schrol tourmaline but I am new to rockhounding. They are dark green though.

Hi Eric and welcome to Mindat.

To me it looks like epidote.

Looks to me like a typical pyroxene or amphibole found in the Bancroft area. Schorl and epidote are uncommon in that region. The last photo looks like the crystals are associated with massive calcite, which can be removed with acid, probably revealing better crystals that are not weathered or damaged.

As stated above your phone would take better photos if you had the rock on a bench (ie not moving in your hand) and you held the phone very still or better yet attached to a small tripod.

And as Don said: please see the Mineral Identification post pre-req list.

Cheers

20180915_013743.jpg looks a lot like ferrorichterite in calcite

It may look like ferrorichterite but that does not mean it is ferrorichterite. To know what species it is will require detailed chemical and maybe structural analysis as well. At this point it isn't even known if it is an amphibole or pyroxene. The only thing I would say with any confidence is that it is not epidote or schorl (or tourmaline) .
