Vintage silver‎ necklace

Blue stones in silver filigree vintage necklace Condition is great, no missing stones I’m not sure of the age, I bought in 2001-ish boutique that had vintage pieces. I do not know what stones or metal this is. Silver has some patina originally and I have never cleaned this necklace, the color didn’t bother me. I’ll be happy to any any questions and try to get better photos if you are seriously interested. * smoke free seller 🌸
