this is my trinity ring stacked with my engagement ring and wedding band. I *think* it is the 1.5mm... the skinniest one? I normally wear it with my wedding band (bottom one) and a 1mm-ish eternity on top. I love it! You should def go for it.
I love this look! Your Trinity does look like the skinny version too - I love how you have stacked it with your eternity and e-rings too
