The Tahitian Black Pearl Choker is made from the rarest and most valued of all pearls and is known as the 'queen of pearls' and the 'pearl of queens'. This string of 31 pearls with diaphanous peacock overtones has a high lustre; each pearl's diameter measures between 13-14mm, a size that pitches the pearls at the upper end of the value and rarity scale. The 44cm (17in) choker is fastened with a superb 18-carat white gold ball clasp. The choker is available to buy with a pair of Tahitian Black Pearl Studs with white gold fastenings.
