Our take on the 10K Solid Yellow Gold Box Chain Necklace 20" 0.8mm

A 20-inch, 0.8mm box chain in 10K solid yellow gold, stamped 10K and finished with polished facets that catch light. Box links give it a squarer, more structured look than a cable chain, and the thin 0.8mm width is meant for small pendants or layering. The best new price is $295.32 at Walmart as of November 5, 2026, with 4 stores selling it new.

Pros
  • Solid 10K yellow gold, stamped 10K
  • Polished facets give a bright, sparkly finish
  • 0.8mm box links hold a shape better than a fine cable chain
  • 20 inches sits at or below the collarbone on most adults
  • Comes in a gift box
Cons
  • 0.8mm is thin; heavier pendants will strain it
  • Owners report the clasp loop can break before first wear
  • Box links kink and twist more than round links
  • Only 10K, so less gold and a paler color than 14K or 18K

Questions and answers

Is 0.8mm too thin for everyday wear?
It is fine for a small pendant or layering, but it is a delicate chain. Skip heavy pendants and check the clasp loop, which owners say is the weak point.
Is this real gold or plated?
It is 10K solid yellow gold, stamped 10K, not gold plated. 10K is about 41.7% gold, so the color is a bit paler than 14K.
Will a pendant fit on this chain?
Yes, if the pendant's bail opening is wider than the chain's links. A 0.8mm box chain suits small, light pendants; large or heavy ones will pull on the thin links.
What length should I pick?
20 inches sits at or just below the collarbone on most adults. Choose 16 or 18 inches for a closer fit and 22 to 24 inches to wear over a neckline.
What comes in the box?
The necklace and a gift box. Nothing else is included.
Is $295.32 a good price?
It is the best new price among the 4 stores selling it new as of November 5, 2026. Compare against 14K box chains of the same width, which cost more but wear better.
