I noticed this piece on NPR this morning (https://www.npr.org/sections/goatsandsoda/2019/02/02/660636686/senegals-stunning-gold-jewelry-and-the-controversial-women-who-wore-it), and while it is not technically lace, it certainly reminds me of lace.  This is about gold jewelry from Senegal that is worked with filigree.  There is more information and pictures on the Smithsonian's website (https://africa.si.edu/exhibitions/current-exhibitions/good-as-gold-fashioning-senegalese-women/).  Perhaps it will inspire lacemakers, particularly those who like to make wire lace.
