Looking for a Unique Engagement Ring

My partner doesn't want a traditional engagement ring, so I've been searching for something different. I recently came across this collection of fancy blue lab-grown diamond rings:

The designs look unique without being over the top, and I like that there are different metal options and settings to choose from.

Has anyone here proposed with a blue diamond engagement ring? How did your partner react, and would you recommend going with a colored diamond instead of a classic white one?
