Hi,

A friend of mine is trying to find the name of an 
anime/cartoon series she watched in the 80's. She 
said it involved a husband and a wife. The wife 
has a beautiful necklace, and she gets kidnapped. 
The husband finds her in a cave of rocks. I'm 
sorry that there's so little to go on, that's all 
she remembers. If anyone can help, I'd really 
appreciate it. Thank you!
