No it’s not a sparkly cut, it’s more flashes of light. It’s defintely not as impactful as an emerald cut/other step cuts eternity band, but those are much more expensive since baguettes are accent stones.
I think when you’re deciding on a baguette, you have to want this understated look. Dull is a matter of opinion, if you’ve never handled a 2mm baguette band in real life, your expectations may lead you to disappointment.
For me, I purchased this ring to stack, and for a contrasting look, it met my needs.
