The wonder.. the LOVE bracelet from Cartier.
The
Love bracelet (styled L
⊝V
e, with the horizontal line inside the letter "O" alluding to the bracelet's
locking mechanism) is a famous piece of
jewelry for
Cartier designed in 1969 by
Aldo Cipullo. The bracelet quickly became popular for its intentional
[1] resemblance in function to medieval
chastity belts. The earlier bracelets were gold plated, while more recent examples are solid gold.
The locking mechanism
Unlike traditional bracelets, which are either wide enough to slip
them over the hand onto the wrist or can readily be opened in order to
put them on, the Love bracelet is designed to be opened only using a
special
screwdriver that is supplied with every bracelet.
[2]
The screwdriver is also available in the form of a necklace, allowing
the bracelet to be "locked" onto one person while the "key" is kept
around the neck of another as a symbol for their
commitment to their relationship.
The screwdriver does not act as a secure
key, however. The Love bracelet can actually be opened with any standard
slotted screwdriver.
