What kind of gemstones are in the great lakes?

Question

by gemstones i mean semiprecious stones and precious stones.

Answer 1

There are no gemstones but there is a lot of natural silver on the beaches of Lake Superior about 20-40 miles northeast of White Pine.

Answer 2

Precious stones aren't formed in lakes. You'll find lots of sedimentary rocks, but very few gemstones.

Answer 3

Yeah I live about 2-3 miles from eerie and Im pretty sure the closest thing you'll find to a gemstone in there is maybe something dropped by somebody from grosse isle or on a dead body.

Answer 4

only semi-precious stones you find along the great lakes is "Beach Glass"

Lake Erie has a mineral "rock salt" the stuff you use in the winter to thaw the ice on your sidewalk

Answer 5

I am not aware of any gemstones here in the Michigan area. There is mining for iron ore and copper.

Answer 6

there's superior agates and thompsonite, and some sort of little green things called superior emeralds, but as for real stones, I'd look elsewhere.

I suppose there's good amethyst near Thunder Bay, Canada, and all sorts of Copper minerals near copper harbor...

Answer 7

One rock that comes to mind is Lake Superior Agate.
