Lg round turquoise stone, ironwork design Chinese design leather cord necklace

This is a handcrafted, interesting necklace that I purchased at a street fair. It is obviously preowned in good condition, the leather cord does have some signs of wear. Can be put on over your head and tighten to make it shorter if you want to. The iron work looks like a Chinese type design it’s quite heavy and it looks like it’s a Chinese turquoise. I think I paid about $150 for it.
