It's a shale sedimentary like crystal with a dark green color to it. Transparent when held up to the light, and looks white and green, with green dots and dashes. It also shimmers golden color on the surface.
I was looking at Fuchsite. But I'm not sure if that's what this is

My indoctrintion included many questions, so I hope you don't mind. So, you say it is translucent. Is it opaque?

Second question: Is it very hard. I am going to assume it is not. If you can scratch it with a knife or a nail file, it is under5.5 on the Mohs scale.

Nothing I could find matched but some questions will make it clear. It could be beach glass, a guess, but not unlikely. The weathering makes it difficult.

It looks like or fluorite or green aventurine to me. I have a big chunk of it here so I attach a picture of it for comparison. Hope this helps a bit.

Does it shimmer silver and gold?
After exposure to light, some flourite will flouresce, glow in the dark.
