It's found in a wide range of colors, and can take many different crystal shapes.

I guess I am quirky that way.

A location would help. An alternate ID to Mels's would be smokey quartz (black crystals), on microline feldspar (white blades) with stilbite (golden-orange crust). I have a piece from the Lovejoy Pits, Carrol County, New Hampshire that looks a lot like your specimen.

If the black crystals are brittle, Mel wins ... schorl. If the black crystals are glass cutters (smokey quartz, Moh's 7), I am leaning towards New Hampshire.

I agree. Barite is soft, yet dense. The Crystal structure fits barite as well. The orange colored crystals might possibly be siderite. The black, sphalerite. My two cents.

Straight sided tourmaline habit is easily seen.

rocknrob: That was one heck of a windstorm that thankfully missed me. I guess Seatac almost hit 60mph gusts. I bet those were some fun landings Nov 20, 2024 21:55:16 GMT -5
