OK, I found this last year when I went on a trip to Texas. But since i got back into rockhounding i found this Bonnie. I know that is a purple type of opal, but I do not know the actual type of rock, I have just been talling everyone it’s a Tiffany Stone 😅 please help. I will post a picture before I started to polish. I guess I actually only have a picture with light through it 😞 sorry.
