I found these near Cornwall Furnace in Lebanon PA this spring.

They are small. Magnetic.In good light they are brilliant and sparkly.

Could it be some kind of quartz ?

Thanks and peace

Ya know - I dont know where it falls hardness-wise , but I will check it out tonight.

I really like the lil guys - I hope to find bigger pieces next time .... whatever it is !

Hi,

if you say it's magnetic then maybe it's magnetite. At least the specimen on the right. Black pyramids or octahedrons? The specimen on the left looks a bit like hematite or ilmenite to me.


Cheers

Philip
