Black and Red Minerals on Beryl - Case Quarries, Portland, CT
June 28, 2012 02:01AM
I was digging through my minerals I collected from Case Quarry about 10 years ago and couldnt figure out what this was on the piece of broken beryl. There are garnets in the area, but the ones I found were not clustered like this. Any Ideas?

The red one looks like garnet (almandine-spessartine series). The black one could be mineral from columbite group ( if it has sub-metallic lustre) or schorl (vitreous lustre).

Probably garnet, but do you want to spend the money to find out for sure what kind it is? All someone can do there is give you a likely guess from a photo which is not very good. Specimen value is less than a dollar. A proper analysis is probably around $50.

There's nothing wrong with labelling it as garnet. It's one of my favourite minerals to collect - I don't get much opportunity to collect it in England - so well done.
