South Sea Pearl
Pearls are graded by their luster and orient. Rare Keshi pearls are formed when an oyster creates a pearl around the mantle tissue.
Richard Burton presented the irreplacable pear shaped "La Peregrina" pearl, which had once belonged to Queen Mary 1 of England, to Elisabeth Taylor as a Valentine present. One day the pearl went missing – apparently her puppy had chewed it! Meaning the Pilgrim or Wanderer, La Peregrina was sold in 2011 for US$11 million.
