I've been sitting on a design for an engagement ring for a while, and approached a jeweller to create it. They've sent over these images for the design, and now I'm uncertain. But I can't put my finger on why, after having this concept in mind for months now.
Should note the gemstones are intended to be Alexandrite and green sapphire.

I'd like people's thoughts, just to see if I've got in my own head about it.
