Any idea on this stone?
I'm actually wondering about the stone.
Made in 40s/50s Germany. 585 gold and real diamonds. I've tried researching and have been told aquamarine, blue topaz, blue spinel and synthetic blue spinel. It's pretty freaking big. (Like over 20 carats big). Do you think this is worth sending in to find out for sure? I'm gonna include another ring in pics just to try to demonstrate size. The small one is i believe 12 carats. Anyone have advice on what to look for to tell exactly what it is?
