Is this ring solid gold or plated?

It is solid 10k rose gold, stamped as such. There is no plating layer to wear through, so the color stays as the metal is polished.

Can it be worn as a wedding band?

Yes. At 1.5mm it is a slim wedding band, and many buyers wear it alone or paired with an engagement ring. If you want a band that reads clearly on its own, a wider band may suit you better.

How does 10k rose gold compare with 14k?

10k has a higher alloy content, so it is harder and more durable but slightly less pink and less valuable per gram than 14k. 14k holds a richer rose tone and resists scratches a little better.

Will it fit next to another ring?

The narrow width and flat inner profile let it sit close to other thin bands. The milgrain edge adds a slight ridge, so it pairs most cleanly with plain or similarly textured bands.

Thin bands with milgrain edges can be resized, but the texture near the sizing point may need re-finishing. Ask a jeweler to confirm before buying if you are unsure of your size.
