Vintage 12kgf Chain, Jade Bracelet, MARVELLA Pendant Bundle

Vintage 12kgf Chain, Gold Tone Jade Bracelet/Pendant Bundle
Gold filled chain is 24″ long, weighs approximately 12.22 grams and the spring ring clasp is stamped 1/20-12K-GF, the jump ring is stamped L.F. 12K G.F.
Pendant is faux jade, signed MARVELLA from the 1950s – 1960s
The “jade” stone is made of pierced molded glass (Chinese Glass) which is prong set in a lovely gold tone setting. The filigree work on the back is actually pretty enough to wear that side showing for a change up.
The bracelet is unmarked. It’s 6 panels of what appears to be genuine jade but I am not an expert. One panel is cracked. LOOK AT PICS. It’s on the back panel near the hinge so it’s underneath and not extremely noticeable. It has no clasp it just closes with a spring mechanism and secures with the safety chain. I would say it’s probably a medium sized 7, if your wrist is very large the bracelet will stay on but may pop open slightly. A jewelry store can probably add a clasp if it’s bothersome.
