Solid 9K Gold Curb Chain 16”

See photos for makers hallmark. There are 5 stamps on the metal but they are too small to read without a loop. Was purchased from a reputable UK retail jewelry store: either Beaverbrooks or Chisholm Hunter, can’t remember which one. Stamped 375. 16” curb chain. Chain is very dainty with small tight links that shimmer subtly in the light. Good quality - very sturdy. 9K chain has a “champagne” color due to lower gold content
