I’m going call it a Beekman Triangle due to its size & equal-lateral dimensions

It’s in great shape after being tossed in heavy gravels for centuries. It’s also quite polished.







This flake could have been a tool used with surgical precision.

Thanks Tdog.
I’ll take a stab.
The triangle looks to be made of a very dark banded Rhyolite. I’m open to other suggestions, as it’s not a lithic I am familiar with.

The Flake/blade is made of a very prolific regional lithic called Marblehead Rhyolite (Source/New England Typology). The base color of this lithic ranges from maroon to grey to black. Easily identified by the bold whitish phenocrysts. Though, this flake is slightly translucent on the edges and the phenocrysts appear to show iron mineral deposits.
