I have 5 “Small Flat Rate shipping” filled with “Cumberlandite” ruff up for trade if anyone is interested. I would like to trade for other interesting slabs. (I don’t have the access to a slab saw yet) When polished it gets a very black with silver metallic finish to it. Great for Pendants. If interested let me know, I can also get bigger pieces if you wish.
You will get pieces like ones in images.
Thanks,
Mike

Key Facts:

Cumberlandite is very rare.

Deposits have never been found outside of Rhode Island.
The only known concentration of this rock is a 3.7-acre deposit in the town of Cumberland, Rhode Island.
Smaller specimens deposited by glacial action occur south of the source as far away as Narragansett.

The United States Geological Survey estimates the formation of Cumberlandite a range between the Late Proterozoic (as much as one billion years ago) to the Devonian (as little as 370 million years ago).

Cumberlandite has a high specific gravity of 3.82-3.88.
Cumberlandite is magnetic. Commonly mistaken for a meteorite.
Cumberlandite contains titanium.
Cumberlandite is the state rock of Rhode Island.
Cumberlandite was mined during the Revolutionary War for the production of cannons.
