Natural gas can take millions of years to form. It is created from the decomposition of organic matter, such as dead plants and animals, under high pressure and temperature deep beneath the Earth's surface.
A natural pearl inside an oyster can take anywhere from 1 to 3 years to form. The process begins when an irritant such as a grain of sand or debris enters the oyster and the oyster secretes nacre to coat the irritant, forming a pearl over time.

No, pearls do not form from raindrops. Pearls are formed inside oysters when an irritant (such as a piece of sand or debris) becomes trapped inside the oyster. The oyster then secretes layers of nacre around the irritant to form a pearl over time.
Natural pearls take years to form, and they are basically an accident. If something as small as a grain of sand gets into the oyster, the muscle/flesh becomes irritated; therefore coating the flesh with a cement covering. This continues for many years until you have a pearl. The chances of finding a natural pearl are quite low, thus the value increases.
A natural pearl, which is rather rare, can form over a wide range of time periods, ranging from years to decades. Cultured pearls, which are simply man-made spheres implanted into the appropriate species of shellfish and covered with thin layers of nacre, take a much shorter time, and are harvested after one to five years.
While white, and more recently black, saltwater pearls are by far the most popular, other color tints can be found on pearls from the oceans. Pink, blue, champagne, green, black and even purple saltwater pearls can be encountered, but to collect enough of these rare colors to form a complete string of the same size and same shade can take years.
A natural pearl begins its life inside an oyster's shell when an intruder, such as a grain of sand or bit of floating food, slips in between one of the two shells of the oyster, a type of mollusk, and the protective layer that covers the mollusk's organs, called the mantle.In order to protect itself from irritation, the oyster will quickly begin covering the uninvited visitor with layers of nacre--the mineral substance that fashions the mollusk's shells. Layer upon layer of nacre, also known as mother-of-pearl, coat the grain of sand until the iridescent gem is formed.Cultured pearls are made in the same way. The only difference is that instead of accidental circumstances, a "pearl farmer" embeds a grain of sand into the mollusk. But It Takes 6-8 Years to make the pearlit can take up to 35 years for a clam to make a pearl because its lazyIt can take as little as a few months to form a seed pearl (natural). Cultured pearls vary by species and take as little as six months (short-cultured akoya) to six years (large, tissue-grafted freshwater).Well, it depends on the type of pearl, what color and how big you would like the pearl. I'm assuming you are talking about cultured pearls, since you asked how long. Akoya pearls can take up to one to two years to culture and Black Tahitian pearls can take up to seven years to be cultured. As for natural pearls, you never know because they are natural, but the smaller ones can grow within a year.More information and pearls here: http://www.pinnaclepearls.com
It takes just as long as by natural means. Homeopathy is a form of sympathetic magic, and it only works for quenching thirst.
Fossil fuels, such as oil and natural gas, take such a long time to form that they are considered nonrenewable on human timescales. Once they are extracted and used, they cannot be easily replaced within a short period of time.
