I adore the way this chain exudes an antique charm while still maintaining a fresh and modern appearance. The rectangular links; (are they biker or oval belcher?) I’m torn between the two, but they look fantastic when paired with the dog clip. I believe the swivel dog clip is a replacement because it’s made of 18 carat gold, while the chain is 9 carat warm yellow antique gold.
Hallmarks - none visible, chain tested as 9 ct, dog clip tested as 18 ct.
Measurements - The weight is 10.2 grams with a length of 22.5 inches. The links are 2.41 mm
Condition - the links are hollow and have no signs of dents , squashing or thinning  just age related wear. The dog clip shuts nice and tightly.
