I was worried about the fit since my engagement ring has a slightly tapered band, but the four size options made it easy to find one that sits nearly flush. The diamonds catch light beautifully without looking flashy, and after three months of daily wear there's no loosening at all.

The diamond band sits flush against my engagement ring without any gap, which was my biggest worry when ordering. I went with the smallest of the four crown sizes and it hugs the curve perfectly.

The four size options meant I could actually match the curve of my engagement ring instead of settling for a gap, and the natural diamonds catch light beautifully in person. Wore it all day at work and barely noticed it was there.
