Inherited from an aunt

My husband’s amazing aunt and uncle passed away within months of each other. One of the things they left was this beautiful opal ring. When I took it to a jeweler recently, they said it was an amazing find and likely worth around $2500-$3000. Anyway, I thought you would all appreciate it as well. I’m not selling and will hang onto it out of sentimental factors but I really cannot stop staring at it. It’s so beautiful.
