Make diamond look more blue

[Ellie25]

How do I make this center diamond look more blue? I was thinking a pink halo or maybe pink round side stones. Other ideas?

Enamel or anodize the metal under the stone blue. With or with out a cup, complete or partial.
Varying degrees of what evidence you’ll see it’s there from the side, on how the setting is constructed.

Will that oomph take away from the enjoyment of a blue diamond?
I bring that up because I ponder that, myself. I waffle.

Thank you! Great approaches to consider, and I'm still considering the degree to which I want to influence the natural color. Maybe some on the edges.

Pink diamonds are good, so is rose gold.
