can anyone tell me what type of stone this is. I only find it at one very specific location on a beach here on Long Island. In its natural state it is very smooth and has a brownish color with specks of light material within. It is a hard material but I am able to work it into some beautiful objects using a Dremel with various grinding and diamond bits. While I am grinding the stone it has a grey appearance but after a lot of sanding and polishing it ends up looking like dark chocolate.

Love your work, especially the fish.
Whatever that material is, it's perfect for purpose.
Has it got some weight to it?
