This is a 3mm width eternity ring (slightly larger than most 2mm rings).  The ring is as good as a white gold ring but at a very affordable cost. You can stack it with other stackable rings or just wear it alone or add it to your existing set. 

Solid 925 Sterling Silver. Approx. 3mm Width. Platinum Finish. Tarnish Free. Nickel Free. Hypoallergenic.
