Worth getting these valued?

[Shane_o]

G'day everyone, I just joined this forum and this will be my first post. I don't know a lot about diamonds and I'm hoping to absorb some knowledge. I had a good run off gold rings metal detecting last year and of the 5 diamond ones these two stand out a bit. I was wondering if it is worth getting these valued, I have no idea on the age or value of these. Both are 18ct. Many thanks in advance.

Hey mate - welcome.
Just from the pics, they're not going to be really valuable stones and it'll cost you probably $100 just to get the 2 rings valued. If you're just going to sell the gold, probably forget the valuation and save yourself a few bucks.
Hope this helps
