Dear BigAkoya. While I know your question was addressed to candeyige (and I don't mean to high-jack your question), I thought I'd post some photos I took of the 20-motif Alhambra in WMOP/YG & GMOP/YG. While I know you're interested in white gold, this might give you an idea of contrast. The third photo is black onyx/YG with the GMOP/YG. IMHO the GMOP offers a subtle, but perceptible difference. The fourth photo is black onyx/YG with the WMOP/YG. This gives you the full range of colors and may help to illustrate the depth and subtlety of the GMOP.
The biggest pop, and drama, will be with the WG/onyx. I don't think it's harsh at all--I think it's a gorgeous combination, but the issue is how you feel about it. And since you're already questioning it (and who wouldn't with a SO) it may not be the right choice, at least for now. Another consideration is whether the GMOP will be flattering with your skin tone . . . My SA mentioned that not everyone can wear it; if you have a lot of yellow in your skin-tone, it can look very drab against the face . . . For that reason she also did not recommend the WMOP/WG.
Happyish, thank you for helping addressing BigAkoya's question
