I don't think this will be a high standing ring, but what is high profile to one person, may not be high to another. It's so relative.
I have to say I love the suggestions that were made, it looks alot prettier. A bit of advice that helped me immensely in getting my exact point across to DK was to talk in millimeters about the design. That way there is no room for error or a misinterpretation. Halo, band, shank, and elevation were all jointly discussed in mms and that made sure we were both exactly on the same page.
Also, if you wanted to be able to easily wear a band with this, DK can accomodate that in the design. Just something to think about for the future, as I made the mistake of not thinking ahead in the past with that.
Just thought I would jump in and share these little tidbits! I can't wait to see what you ultimately end up doing!
