Is this chain solid gold?

It is 14k yellow gold but semi-solid, meaning the links are hollowed rather than filled solid gold. You get real 14k gold with less weight and a lower gold content than a solid chain of the same size.

How does semi-solid compare to solid?

Semi-solid links are lighter and less expensive but can dent or crush if squeezed hard. Solid Cuban chains hold up better to daily abuse and feel heavier on the neck.

What does 6mm and 26 inches look like on?

6mm is a medium-bold width that shows clearly without looking oversized. At 26 inches the chain hangs below the collarbone, over a shirt collar or sweater.

Will the clasp hold up?

Cuban chains concentrate stress at the clasp. Check that it closes firmly and consider having a jeweler inspect or reinforce it if you wear the chain daily.

Can I wear it every day?

Yes, 14k gold tolerates daily wear, but semi-solid links are more vulnerable to bending. Avoid sleeping or exercising in it and store it flat to prevent kinks.
