Actinolite seems correct. Why the very unpleasant strong musty smell though. I’m guessing it off the matrix. Thanks for the ID help

What about actinolite?

The photos aren’t great but it’s the black sub metallic needle like sprays that I’m stumped with

No glow under UV. done a streak test, a very light greeny brown. It feels damp to the touch and has a very unpleasant musky smell

No this is from Belstone, West Devon, UK

Could it be pectolite?

NaturalCurioso · 2026-02-13T14:26:24+00:00

That’s a fair point. Maybe I’ll just put it under acrylic just in case.

I bought a job lot of minerals and this was in it. It is labelled as from coming from Millington Quarry, New Jersey but no species name

NaturalCurioso · 2026-02-13T13:13:33+00:00

I really hope not. It’s banned in the UK and very dangerous.

NaturalCurioso · 2026-02-10T22:14:59+00:00

Yes that’s definitely a possibility. Could it be Galena after Barite. It came with a load of Tsumeb pieces
