And I don't know what it is. I wish I had a picture if it , but I'm way too tired to take a picture , upload it , etc. So it looks just like a lense to a pair of sunglasses when you first look at it. But it kind of comes to a point like an elf ear and I is swirly. It's definitely something found in nature like it's not something someone dropped in the water. And I live in Maine btw , haha. It's brown like sea glass brown , I hope that's enough information
