Ladies & Men as well: What is your opinion on this?

Honestly, i'm sure she'd like both. But, along with the consideration of what she likes, look at what she already has. Would the ring match any earrings or necklaces she may have? Also, did she specify what "yellow" she likes? (yellow gold ring or yellow stone?) I personally like the original one you bought her, but if she likes yellow stones, I would've gotten the other one. And yes, they set up lights, zoom in, and get the "perfect" picture so you buy the ring. The best way to buy one would probably be in a store where you can examine the ring in normal everyday light. Hope this helps.
