When the clam was pried open, and the meat scraped out, the local chief beheld something marvelous: a massive pearl, its sheen like satin. In its surface, the chief discerned the face of the Prophet Muhammad. He named it the Pearl of Allah. At 14 pounds, one ounce, it was the largest pearl ever discovered.
Button: Button pearls are flattened to some degree, making them resemble a button or perhaps a disk rather than a perfect sphere. These pearls are often used in earrings where the flattened side can be attached to the setting. Buttons are also categorised as symmetrical.
Depending on the quality, a 16-inch string of 7mm white cultured pearls will set you back about US$20-$200, while the large South Sea variety is priced from $100 for a single medium quality 10mm pearl to $2,500 and up for a graduated 10mm – 14mm, 18-inch strand similar to Ms. Pelosi's.
The most common and popular Freshwater pearl sizes found today range from 6.0-7.0mm up through 10.0-11.0mm. Exotic black Tahitian pearls are naturally larger-sized pearls, ranging from 8.0-9.0mm up to 15.0-16.0mm and larger. The most common and popular size range is from 9.0-10.0mm up through 13.0mm.
Harvesting a pearl does NOT kill the oyster, and Pearl Farming is very much a 'sustainable' practice. Not only does removing a pearl not kill the oyster that produced it, Pearl Farmers are extremely careful not to harm their oysters… As oysters age, they typically produce better and better pearls.
Pearls are made when a small irritant finds its way inside an oyster or mollusk. This can be a grain of sand or a piece of shell but is more typically a little parasite. Nacre is the substance that coats the inside of an oyster or mussel's shell. The nacre coats the irritant, and the layers build up over time.
A natural pearl (often called an Oriental pearl) forms when an irritant works its way into a particular species of oyster, mussel, or clam. As a defense mechanism, the mollusk secretes a fluid to coat the irritant. Layer upon layer of this coating is deposited on the irritant until a lustrous pearl is formed.
The Pearl of Lao Tzu (also referred to as Pearl of Lao Tze) was once considered the largest known pearl. The pearl was found in the Palawan sea, which surrounds the island of Palawan in the Philippines, and was found by a Filipino diver.
Since the company was founded in 1893, their goal has been to put beautiful jewelry around the necks of as many pearl-lovers as possible. Mikimoto makes the important distinction that their pearls are cultured, not natural.
The Tooth Test: To find out if a pearl is real, lightly rub it against the front of your tooth — not against the edge, which can scratch the pearl. If natural or cultured, rather than simulated, the pearl should feel gritty.
The largest oyster is a Pacific oyster (Crassostrea gigas) and measures 35.5 cm (13.97 in) in length and 10.7 cm (4.21 in) in width, as measured in the Vadehavscentret, Vester Vedsted. Denmark, on 17 December 2013. It was found by the Vadehavscentret (Denmark).
Pearls are made by marine oysters and freshwater mussels as a natural defence against an irritant such as a parasite entering their shell or damage to their fragile body. This creates a material called nacre, also known as mother-of-pearl, which encases the irritant and protects the mollusc from it.
Harvesting PearlsSome oysters can produce two to three pearls over the course of their lifetime, but only an oyster with pearls of good quality will repeat the process of producing a pearl.
When a grain of sand gets into its shell, it secretes a shell like substance (nacre) to coat the intruder. Over time, this process results in the formation of a Pearl, one of the World's most treasured jewels.
There are no obvious signs that an oyster, mussel, or clam has a pearl inside. You just have to open it to see; it's kind of like a guessing game. That being said, larger oysters, mussels, or clams may have pearls because they've had a longer time to develop.
A natural black pearl is more expensive and mysterious than its classic off-white cousins. And for good reason: Although manufacturers can dye pearls black, it takes extremely rare conditions to form pearls that have that dark, eerily iridescent glow. This, however, is rare; it occurs in only one in 10,000 pearls.
Some types of plastic emit a chemical that will cause the surface of your pearls to deteriorate. Don't store pearls in a safe or safety deposit box for long periods. Pearl strands should be restrung every one to two years or more often if the thread begins to bag or fray.
Pearls come from a living sea creature: the oyster. These beautiful round jewels are the result of a biological process within the oyster as it protects itself from foreign substances. Although clams and mussels can also produce pearls, they don't do so very often.
Real Pearls Are Cool to the TouchWhen you touch the pearls though, it should have a cool touch to it. Fake pearls are made typically out of a wax or glass, which takes on the temperature of the environment. A warm pearl is fake, while a cool pearl is likely real.
