Vintage RJL Sterling Engraved Heart Necklace

This vintage necklace includes a chain made of sterling silver and has a c clasp closure that is stamped RJL STER, and a heart pendant that is likely also sterling (but is not stamped as such). The pendant is engraved GP and has a lot of wear throughout (may have been a daily wear piece). It doesn't appear that the chain and pendant were created together but were joined together later on. The chain also has some wear but is in good condition. Chain length: 40cm / 15.75" Pendant dimensions: 14mm x 18mm Weight: 3.82g
