Which is better for everyday wear?

The 3mm rope chain. At 12.9 grams with thick solid links, it takes daily wear far better than a 0.45mm to 1.0mm box chain, which buyers describe as too thin and prone to clasp-loop breakage.

Which is better for a pendant?

The box chain. It is built for pendants and comes in widths up to 1.4mm. The 3mm rope is heavy enough that most pendants will slide and twist on it.

Is the rope chain worth about ten times the price?

You are paying for gold weight and size, not brand. 12.9 grams of 10k gold versus roughly 1 to 8 grams explains most of the gap. If you want a thin pendant chain, the box chain is the better value.

The rope chain, by a wide margin. Its 3mm links and lobster claw resist pulling. The box chain's thinnest sizes are where buyers report breakage.

Does the box chain come in longer lengths?

Yes. It goes up to 30", while the rope chain stops at 24". The box chain also offers 16", which the rope chain does not.

Yes. Both are solid 10k yellow gold, not plated. The box chain is stamped 10k; the rope chain is described as solid, real, genuine gold.
