I was worried the four size options would make choosing hard, but the fit against my engagement ring is basically seamless. The diamonds are small yet seriously sparkly in daylight, which is exactly what I wanted for a band I'll wear daily.

The diamond catches light even in dim restaurant lighting, which I didn't expect at this carat size. I ordered the mid-range size and it sits flush against my engagement band without any gap. Wore it daily for three weeks now, no loosening or dulling.

The four size options made it easy to match the curve of my engagement ring instead of settling for a gap. The natural diamonds are small but they catch light constantly, even in dim restaurant lighting. Six months in and the band still sits flush without spinning.
