Odyssey Green Onyx Stacking Ring

I ordered both the Odyssey and the Siren small rings in green with gold to see which looked best with my Siren multi stone ring. I prefer the Odyssey because the setting has thicker gold around the stone and the stone is a little flatter and darker in color. The photo with 2 rings on one finger shows the small Siren green ring on top with a thinner gold setting around the stone, for comparison. Siren stone looks a little more translucent and is larger. If I were just wearing the single stone ring on its own, I think I’d choose the Siren since it’s a bit larger. My finger is size 6.25, bought a 6.5 to be comfort in the summer heat.
