14K yellow gold band. It has a really nice weight and thickness to it, ensuring it is a piece that will last. Has some scuffing, which is normal for gold but can definitely be returned to high polish by a local jeweler. Bought it via an estate jewelry reseller so it is vintage. Listed mejuri only for exposure. Approximately 7.5. I wore this by itself on a larger finger or was able to stack it with several bands on a smaller finger. Really versatile! Weight of approximately 5 grams.
