Cincin Susun Tennis Eternity | Perak Sterling/Kristal Nano Biru Safir

The band is just under 4mm wide, which makes it feel substantial without being chunky, and the blue nano-crystal has a deep, almost liquid glow up close. I've worn it daily for two weeks and it hasn't tarnished or snagged on anything yet.

The sapphire blue catches the light in a way that feels almost liquid, and the 2.5mm stones sit snugly without snagging on anything. I've worn it daily for two weeks and the silver plating hasn't dulled a bit, even through hand-washing.

I was a little worried the 3.9mm band would feel bulky, but it's perfectly dainty and the sapphire blue nano-crystal catches the light like the real thing. I've worn it daily for two weeks with zero tarnish, and it stacks beautifully without scratching.
