Given that pearl is the birthstone for the month of June, La Peregrina is a fitting item with which to mark the occasion.

Likely best known today for having been purchased by Richard Burton for Elizabeth Taylor for the then huge sum of $37,000 in 1969, it later sold for about USD$11 million in 2011.

It has been owned by the Spanish royal court, worn by Queen Mary of England after she married King Philip II of Spain, and acquired by Napoleon Bonaparte before being sold to an English duke.

Burton and Taylor had it set in a Cartier necklace, seen below. Value today? Likely a lot more than the 2011 auction price.
