Hearts on Fire 20” long dainty diamond station chain necklace in 18k gold

This 18k yellow gold chain by Hearts on Fire measures 20” long with a heart shaped jump ring to shorten to 18”. It has a tiny diamond set in platinum. This can be worn by itself, layered, or used as a chain for a pendant. The diamond is purposefully offset so it would be great for that! Originally $400 retail. I think I only wore this maybe once or twice. In excellent condition
