Vintage filigree art deco Kirk's folly silver lace earrings Victorian vtg

These are beautiful I did some research and these exact ones from other sellers say these are by Kirk's folly, they are not signed, they have a very art deco ,Victorian revival style and look. Beautiful lightweight not sure if they are sterling silver or not but they are in VERY good condition, I can put new 925 stamped sterling silver ear hooks or hoops leverback style instead of what's on them, I believe someone added new hooks, just basic hooks. These were from an estate find. measures 2.5" long. Box 12
