Actually oysters are not the only mollusks that can produce pearls. Any bivalve mollusc, such as clams, mussels, cockles, etc. can make a pearl. However most of these pearls are not vaulable. The mantle of the animal creates the pearl. It also creates the shell. Therefore the exterior of a pearl will have the same appearance as the interior of the shell. Pearl oysters (not the kind of oysters we eat) have a highly glossy, iridescent interior. Therefore pearls which they produce are likewise highly glossy and iridescent, which is what gives them their value. A pearl from an ordinary edible oyster would just be dull white, with no gloss at all, because that's what the interior of an edible oyster's shell looks like. Fresh water mussels produce semiprecious pearls because their shells do have a "pearly" interior, though not as "pearly" as that of a pearl oyster.

An ore has minerals or metals suspended in a base, unwanted material that needs to be refined to make the pure mineral or metal usable.\n\nA gem is a crystaline material that has some intrinsic value.

These are different types of tests on determining the validity of a diamond...\n\n1. The old “If it will scratch glass it has to be a diamond.” Well, it is true that diamonds do scratch glass but so do a lot of the other fakes on the market. To boot, it’s possible to injure your rock even if it’s real during your hardness test.\n\n2. The transparency test. If you flip the diamond in question upside down and place it over some newsprint and can clearly read through the stone, it’s not a diamond. (The problem with this test is some diamonds are cut shallow and can be read through.)\n\n3. The fog test. This test I like a lot. Put the rock in front of your mouth and fog it like you would try to fog a mirror. If it stays fogged for 2-4 seconds, it’s a fake. A real diamond disperses the heat instantaneously so by the time you look at it, it has already cleared up. (A down fall to this test is oil and dirt on the stone can effect its reliability and the test is not accurate at all on doublets where the top of the stone is diamond and the bottom is cubic zirconia epoxied together.)\n\n4. The weight test. The most popular of diamond simulants (fake) is a cubic zirconia. C.Z.’s weigh approximately 55% more than diamonds for the same shape and dimension. So if you have a carat or gram scale at your disposal you can see if the imposter tips the scales too much.\n\n5. The U.V. test. A high percentage of diamonds fluorescence blue when put under an ultra violet light (black light). Since 99% of all fakes don’t, a positive identification of medium to strong blue would indicate a diamond. The bad news is if this method proves you have a diamond, it also proves your diamond is worth less. Diamonds with blue fluorescence are as much as 20% less valuable. Remember, lack of blue fluorescence doesn’t mean it’s a fake; it could just be a better quality diamond.\n\n6. Under the loop test. If you own some sort of magnifying lens, there are some things you can look for on the stone that might give away its identity:\n\nA. Look at the rock from the top and see how well the facets (cuts on top of the diamond) are joined. They should be sharp not rolled. \n\nB. Look at the girdle and see if it is faceted or frosty (a clear sign it’s a diamond) or waxy and slick (an indication it’s a fake).\n\nC. While you’re looking at your stone under magnification, look into your stone to see if you detect any flaws (carbon, pinpoints, small cracks). These are typically clear indications it’s the real thing since it’s very hard to put inclusions in a fake. \n\nD. After examining the stone, focus in on the stamps inside the setting. A stamp of "10K, 14K, 18K, 585, 750, 900, 950, PT, Plat" indicates the setting is real gold or platinum which gives a better chance that the stone in it is real as well. While you’re looking at the interior of the ring, also look for any "C.Z." stamps that would indicate the center stone is not a diamond.\n\n\nHOPE IT HELPS!!

Actually both require practise. Depends on your preference actually. More towards westerned string instrument then cello. More towards chinese instrument then erhu. It's about the musical feeling essentially.

The biggest "give-away" of a fake Rolex is the "second" hand.\nA real Rolex watch has a sweeping second hand.  This technology can't be produced cheaply, so if you go to NYC and by one from Chinatown, it'll have a "ticking" second hand.  However, I've seen a fake Rolex with a sweeping second hand at the price of about $700 - $1000.

The biggest difference is:\n\nAlternative = Main Stream and is backed by money and Labels\nIndie = Independent, Underground and generally not released to a mass of people\n\nIn the non literal sense, Alternative is the top of the Umbrella with a ton of musical genre's underneath, including Indie.

You need to have it authenticated. One turned up in Canada recently and it turned out to be a fake.

I recommend you get the cheaper one. They are trying to steal money from people by labeling it "official" as a marketing technique.

The mollusk are killed to retrieve the pearls. Sometimes the pearls form in among the fleshy parts or on the inside surface of the shell where the nacre is made. In either case the mollusk is killed so the pearl can be removed from where it may be attached still to the shell or inside the flesh. In general, the oysters are opened just like you see at the fish market, with an oyster knife and the rest is history.\n\nPearls are formed by any mollusk that can form a shell. The most prized pearl comes from the Pearl Oyster, but other pearls can be found in clams both saltwater and freshwater varieties, abalone, mussels, conch, and so on.

Puka shells are pieces of a Cone Snail shell. Puka is the Hawaiian word for "hole" and refers to the naturally occurring hole in the middle of the shell fragment.\n\nAs the name implies, the shell of the Cone Snail is cone-shaped, being closed at the larger end. While the abandoned shell is tossed in the surf and coral rubble, the pointed end is ground into sand. The "puka" is formed when the minor apex of the large end is eroded by the same forces that wears off the point.\n\nNecklaces, bracelets and anklets are a perfect use of the "shells" because they already have a hole for stringing. Puka jewelry first became popular in Hawaii though the Cone Snail is found throughout the Indo-Pacific ocean.\n\nPuka shell jewelry used to be fairly expensive due to the labor involved in collecting enough naturally formed "shells" for a suitable string. Currently the Cone Snail shells are often harvested and other types of shells may also be used for faux puka jewelry.\n\nAuthenticity may be determined by simple observation. An overtly glossy patina indicates the shells have been tumble polished. If the edges are chipped, the shells were harvested and manually broken into shape. If the "puka" is perfectly circular, then the hole was assuredly drilled.

If you like them what is the difference if they are fake or real. You won't be laying your hands on them.

all depends on if they are fake or real

I think the main difference between Chinese culture and American culture is that the Chinese have one.
