wikipediaIt (the Pearl of Allah) has been carbon dated to 600 B.C..[4]
hyperphysicsCarbon dating is a variety of radioactive dating which is applicable only to matter which was once living and presumed to be in equilibrium with the atmosphere, taking in carbon dioxide from the air for photosynthesis.
To me this clearly indicates that the abalone shell or pearl itself wasn't carbon dated, but other artifacts near it, were. That is also a record-setting age for human use of pearls, too, but that needs its own thread.Prehistoric Use of Pearls by Man
The history of mans' use of pearls as gemstones is also of interest to me, and in this regard, I have been examining anthropological collections of Chumash Indian abalone artifacts curated in U.S. museums. For instance, collections of Chumash Indian burial artifacts at the Santa Barbara Museum of Natural History include pearls which evidence features clearly abalone in origin. These natural abalone pearls consisted of many typical tusk and baroque-shaped examples, which apparently been mistaken by anthropologists in past for polished, mother-or-pearl beads. Carbon-14 data accompanying these Chumash burial artifact collections suggests that it may be possible to pre-date man's first use of pearls to nearly 8000 B.P.
Electron spin resonance dating
This dating technique measures the electrons of the mineral hydroxyapatite trapped in the crystal structures of teeth, coral, or seashells. The greater the number of trapped electrons, the older the specimen. Electron spin resonance can date tooth enamel, coral, or seashells as old as 1 million years.
[/FONT]Carbon-14 or radiocarbon dating
When an organism is alive, it contains a ratio of carbon-12 and the isotope carbon-14 that is the same as the ratio in the atmosphere. When the organism dies, C-14 decays and the ratio between C-12 and C-14 changes. Scientists measure this change to determine when the organism died. This technique works on organic material, such as wood or bone, younger than 50,000 years.

WD Cobb in AMNH bulletin 1939 #44Nearing the Panglima's house, we were greeted by sounds that seemed to be the climax of some Mohammedan celebration. ....... In this image (of the pearl) the Panglima was startled to discover a resemblance to Mohammed. Then as his excited servants stood in awe, the old man prostrated himself before the pearl and began to pray. It was this act of religious devotion that incited the frenzied celebration throughout the whole tribe which we were now witnessing.
