We are alike!! Mine is an eternity style with flush diamonds 😆 I only had them set halfway around. My band is wider than usual with a bevel either side of the diamonds. 18ct gold and it was £700.
We found a local goldsmith who made ours in 2 weeks, also a last minute wedding!!!

I had bought two from jewellers and returned them as I didn't LOVE them and started to feel how you describe about having the right ring on the day. No engagement...
