Looks like opal to me also - nice pendent, likely gold setting - look for marks on back
Took me 3 years to find my first gold -
Nice find!!!!
Thanks! I need to get myself a magnifying glass. As far as I can see, I see a tiny number 5 or 3 on the back. It seems to be gold plated, but it is so small. Opal makes more sense after looking at some photos. I can tell I am going to get addicted to metal detecting, lol. Lots of fun. Reminds me a lot of how I feel when I go fishing....Similar mystery type mindset. I found a bunch of coins out there too, but nothing earlier than the 70's.
