These are thecorrect period-authentic parts for restoring multi-strand necklaces to original condition. • Material: Brass with gold-tone finish. Lot 20 Pcs Miriam Haskell Restoration Slide Clasps Pat 3427691 Necklace Bracelet These are  original patented slide clasps  stamped  U.S. Patent 3,427,691 , a late-1960s design used on  high-end New York couture costume jewelry . This specific patent number is  documented on Miriam Haskell  multi-strand necklaces and bracelets from the mid-1970s through the 1980s, and has also been observed on  Robert DeMario and Hobe  pieces from the same era. These clasps were supplied by a specialized New York findings manufacturer and were  never sold retail . They are now highly sought after for  vintage jewelry restoration . Modern replacements do not match the size, finish, or locking action of these originals, and using incorrect hardware can significantly reduce the value of a couture piece. These are the  correct period-authentic parts  for restoring multi-strand necklaces to original condition.

Please look at all the photos, as they are part of the description. I try my best to point out any flaws. Also please remember this is a preloved piece and may show signs of light wear, scratches, marks, etc. Thanks for stopping by Condition: Pre-owned.
