I once spotted a really cool orange clay trade pipe laying just under the shallow water in the Flint River just south of Albany Georgia. When I saw it, my heart raced and I quickly pulled it from the gravel bar and was very happy to have something new to add to my collection. After I pulled it from the water, I sadly discovered it was an orange rubber cover to a lawn mower spark plug. So goes the world.
Looks like coconut shell
Yep, it is a piece of coconut shell.
