This is a gorgeous ring!!
My DF and I custom made my ring through Gemvara. They do wonderful work and my picture doesn't do it justice. It is Iolite center surrounded by white sapphires. I love it! There is also a matching band of white sapphires to fit underneath the engagement ring.
I got a non-traditional ring too. I told my FI that I didn't want any diamonds mainly due to conflict diamond issues. So here's what he got me, and he made sure the diamonds on the band were conflict-free. He also got me a wedding band with diamonds so I wouldn't get diamond envy, which were also conflict-free.
