With appendix letter stating:
The  natural pearl described in Test Report No 72642 from the Swiss  Gemmological Institute SSEF possesses extraordinary characteristics and  merits a special mention and appreciation.
The described  natural pearl exhibits an impressive size and weight of 33.147cts  (132.59 grains), combined with an attractive roundish shape and smooth  pearl lustre. The pearl shows an attractive white colour with weak ros?  and green overtones, poetically also referred to as the 'orient of  pearls'. Such overtones are due to an iridescence effect caused on the  surface of pearls and greatly contribute to their beauty.
The combination of well-balanced trace elements found in this pearl is characteristic for a saltwater pearl.
A natural pearl of such a large size and quality is very rare and exceptional.

Documentation  of historic round pearls can be prone to conflicting details and some  pearls, over the years, have simply disappeared. Although some were  recovered, the entire French crown jewels were stolen when the Garde  Meuble (Royal Treasury) was stormed in Paris during the French  Revolution in 1792. An inventory of the jewels had listed a 388 grain,  round pearl just a few months previously. It has not been mentioned  again.
A pearl of 148 grains was referred to in Taverniers  Voyages (1676 - 1679) as being a gift to the Great Mogul from Shah  Abbas. Again, it has not been mentioned since.
However, it is  certain that the 33.14, or 132 grain pearl to be offered on May 1st 2014  is one of the largest round pearls ever to be offered at auction.
