Is a lightweight 10mm band durable enough for daily wear?

It holds up for normal wear, but the thin wall can dent or bend if knocked hard. Treat it as a comfort ring, not a heavy-duty work ring.

Can this ring be resized?

Lightweight and hollow-style bands usually cannot be resized without risking damage. Choose the right size up front, and size up if you are between sizes.

How does 14k compare with 18k gold here?

14k is harder and more scratch-resistant, which suits a wide band. 18k has a richer yellow color but is softer and shows wear faster.

Does a 10mm band fit comfortably next to other rings?

A 10mm band takes up a lot of finger space. It works best worn alone or with a very thin ring, and some people find it tight between fingers.

Is this a men's or women's ring?

It is unisex. The wide flat profile is often bought as a men's wedding band, but the plain shiny finish works for anyone who wants a simple gold band.
