Vintage Lucien Piccard huge runway necklace.

This necklace is HUGE & heavy almost hurts to wear it! I think it is likely late 70's to mid 80's. Signed on the back Lucien Piccard. I am not all that familiar with this name but I liked the piece when I saw it and I took a chance and paid $12.00 which is more then I normally would pay for something I am unsure about. But I did a quick search on eBay and I see these pieces sell for a decent price and I did fine. Thanks for looking.
