This gorgeous vintage necklace is solid 14k yellow gold and was a custom made piece.
I tried to take several closeups of the unusual links.
This chain is 5mm wide.
It measures 18 inches from end to end.
Weight: 19.1 grams.
Marks: 14 inside the clasp.
Clasp and chain were both acid tested (solid 14K) by a professional jeweler.
The loop opposite the clasp is not original and is not solid gold.
