The patented clasp

Developed by Jean-Charles Pellegrino, the EVM® clasp is a patented innovation designed to securely hold earrings in place over time, without compromising the comfort or the aesthetics of the piece.

Discreet, reliable and easy to use, it integrates naturally into demanding fine-jewellery creations.
