Hello everyone! I was wondering if anyone could help with identifying or guessing what type of stone I've found. First of all, I live in central Georgia near the Flint River. I found the rock at my grandmother's house. The people that lived there before her goes to the river sometimes so I thought that's where it came from. It's also smooth like, flat and can extremely tiny shimmers on it. When I shine a regular light on it, the light shines through. When I use a UV light, it doesn't seem to go through and reflects with a star pattern. It does seem to have a wax like texture. Pictures are included. I really appreciate any and all replies. Thank you so much!
We've been getting a lot of people asking for help identifying rocks where most of us specialize more in gems. As a gemmologist, if someone was to have asked me to look at that rock I would be calling upon my friend who is a geologist to take a look at it as that would be more their wheelhouse. If you want, try posting those images on a website for geologists or finding one of the many Facebook groups dedicated to identifying stones.
Pictures are never a good way to really take a guess at stones either way though but based on your description I would be leaning towards a type of polycrystal Quartz. There are a bunch of different varieties of it that I wouldn't be able to even start guessing to which type it is. Quartz has a very consistent Specific Gravity and Refractive Index so if you had a way to test either of the two it might help to confirm if it is Quartz or not but even with that it doesn't trump the experience of a local geologist that would be able to give you a better idea. Take a look in the area for any post-secondary schools and see if they offer a geology program and maybe ask them.

You can also try MinDat.org. Search locality "Georgia" and do some research of your own on common minerals of the state. Like. https://www.mindat.org/min-52455.html
