It's rather large and heavy.. It looks like a diamond but I know it's not lol. It's clear and shining, very pretty, I'll attach a picture
Thank you in advance!
Crystal shining, clear almost diamond like some cloudy formations in the middle
Having a hard time adding an attatchment.. I'll add one on a separate form.

Thank you!

If you had a Long/shortwave Ultraviolet Light, you could see if it flouresses, If it doesn't, it's not a diamond.
A Pawn Shop or Jeweler may do a Quick test for you?
