Vintage Mexico sterling silver earrings 70's Taxco modernist Brenda Schoenfeld ?

These are unusual and VERY VERY nice rare earrings! I don't see anything like them listed anywhere online at all! These were from an estate and were said to be by Brenda Schoenfeld, they are signed on back 925 and Mexico Taxco I assume? They had other Brenda Schoenfeld pieces These are not signed by designer that I can see. either way they are very special earrings. Such a nice and unique design. Very high quality you can see and feel immediately. Please no lowball offers, my price after all fees I pay isn't much over what I've paid. box 30 measures- 1.25" tall You can see the Mexico on one earring, the other you can't quite make out, these are older. excellent condition, you can polish if you'd like.
