Pearl of Lao Tzu
The pearl was found in the Palawan sea, which surrounds the island of Palawan in the Philippines, and was found by a Filipino diver. It is not considered a gemstone pearl, but is instead known as a "clam pearl" or "Tridacna pearl" from a giant clam. It measures 24 centimeters in diameter (9.45 inches) and weighs 6.4 kilograms (14.2 lb).
The pearl came from Brooke's Point, Palawan in the Philippines. Wilburn Cobb, an American who brought the pearl from the Philippines in 1939 and owned it until his death in 1979, published an account of how he came to own it in Natural History magazine. According to Cobb, he wanted to buy it from a Philippine tribal chief when he first heard of it in 1934, but the chief, a Muslim, did not want to sell because he considered the pearl sacred, in part because of its resemblance to the turbaned head of the Islamic prophet, Muhammad. However, Cobb relates, he saved the life of the chief's son, who was stricken with malaria, in 1936 and was given the pearl as a token of gratitude. Because of its sacred associations, the pearl came to be known as the Pearl of Allah.
Much later, Cobb wrote a new account in the February 1969 Mensa Bulletin, this time promoting the pearl as an artifact of Chinese legend. He alleged he had been approached by a Chinese man named Li, who told him that the pearl had first been grown in a much smaller clam around a jade amulet inserted by a disciple of the legendary sage Laozi more than 2,500 years ago, and been transferred over the centuries to ever larger clams, growing to record size. Wars had supposedly been fought over the artifact, and it had been sent off to the Philippines as a protective measure, where it was lost in a storm.
After Cobb's death in 1979, Peter Hoffman and Victor Barbish bought the pearl from his estate for $200,000. Barbish has claimed to have had further contact with other Li family members. (The legend of a "Pearl of Laozi", however, is only known from the claims of Cobb and Barbish.)
When Victor Barbish borrowed money from a Joseph Bonicelli, he gave him an interest in the pearl. In 1990, Bonicelli took Barbish to court to collect his loan, and the court ruled that Hoffman, Barbish and Bonicelli were equal partners in the pearl. Bonicelli died in 1998, and after more legal proceedings, the court ordered the pearl to be sold (it has not been), with a third of the money going to Bonicelli's estate. It is not on display to the public and as of 2008[update] was being held as part of the probate inventory of Victor M. Barbish.
The pearl was owned in three equal shares by the heirs of Joe Bonicelli, Peter Hoffman and Victor Barbish.
While biologists would regard this object as a kind of pearl, gemologists regard it as a non-nacreous pearl, lacking the iridescence of the pearls that come from saltwater pearl oysters and freshwater pearl mussels. Because of its great size, a giant clam can create a very large pearl, but not an iridescent, gemlike one. The Gemological Institute of America (GIA) and CIBJO now simply use the term "pearl" (or, where appropriate, the more descriptive term "non-nacreous pearl") when referring to such items, rather than the term "calcareous concretion" and, under U.S. Federal Trade Commission rules, various mollusc pearls may be referred to as "pearls" without qualification.
Gemologist Michael Steenrod in Colorado Springs has appraised the pearl at $60,000,000 (1982) and $93,000,000 (2007). Another 1982 appraisal, by Lee Sparrow who owned a gem laboratory and appraisal business in the Phelan Building in San Francisco, put the pearl at $42,000,000.
In America, the pearl was exhibited at the Ripley's Believe It or Not! Odditorium in New York, valued at $35,000,000.
The Palawan Princess, then considered the second largest pearl, was offered at auction by Bonhams and Butterfields of Los Angeles on December 6, 2009. The five pound pearl was estimated to achieve $300,000 to $400,000, but it was not sold.
