This is because a real pearl has small ridges on its surface. These ridges may not be visible to the naked eye. However, experts and jewelers can check the “natural flaws” in a pearl using a magnifying object. In real pearls, these same ridges can be felt using the teeth.
Fake pearls only shine on their surface and their luster has no depth. Uniformity: A fake pearl necklace, for example, will have pearls that are all the same size and perfectly spherical. In addition, they won't have any blemishes or imperfections when examined very closely.
The pearl tooth test involves taking a pearl and rubbing it along the biting edge of your teeth. If the pearl is natural, it should feel gritty. A fake pearl will feel slippery and smooth. Some fake pearls will not even massage because they have been created using glass or synthetic materials.
The qualities that determine the overall value of a natural or cultured pearl or a piece of pearl jewelry are size, shape, color, luster, surface quality, nacre quality, and—for jewelry with two or more pearls—matching.
The Vinegar Test
A real pearl will dissolve in vinegar or show erosion where the vinegar drop meets its surface. This is because of the chemical reaction between the acid in the vinegar and calcium carbonate, the primary chemical that a real pearl is made of.
Jones found that a 5 percent solution of acetic acid, a concentration identical to that of white vinegar sold in supermarkets today, takes 24 to 36 hours to dissolve a pearl weighing approximately one gram. The process leaves a small amount of translucent, gel-like material on the surface.
The lip determines the pearl color. While the white pearls are also priced by jewelers, the gold pearl variety is the most coveted color. The gold South sea pearl's color can range from creamy white to deep gold, and the darker the color, the more expensive it becomes.
Gold Pearls

Some of you may be concerned that if their pearls turn yellow, this indicates that they are fake. Contrary to popular belief, imitation pearls very rarely turn yellow due to their composition of plastic and ceramic. Pearls that begin to yellow indicate that they are organic and subject to change.
Real pearls are cold to the touch. Regardless of the weather, they slowly warm up as you wear them. On the other hand, fake pearls are warm to the touch and don't change temperature. So if you're feeling a cold sensation when you wear your pearls, they're likely real.
Real pearls vary in weight depending on size and type. Generally, they are light but range from 0.5 to 6 grams. Akoya, South Sea, and Tahitian pearls are heavier than freshwater pearls. Larger pearls will also be heavier than smaller ones of the same type.
If the tone/color is the exact same across all the pearls, that points to them being fake. — Similarly, under black light the different pearls should fluoresce differently on a string of pearls, and will tend to fluoresce yellowish or tan. Fake pearls will tend to be uniform across the line.
(Be aware that water can remove the top layer of imitation pearls). Put pearls on last. Perfume and body lotion can affect a pearl's luster; make sure you apply them before you don your pearls. If you wear pearls regularly, have them checked by a jeweler every six months to a year.

The cleaner the surface of the pearl, the more valuable it is. Look for an absence of disfiguring spots, bumps or cracks on the surface of a pearl, also known as "cleanliness." Notice that the highest quality pearls have a sharp, mirror-like reflection.
Perfectly Round pearls are the rarest and most valuable shape there is! Pearl producing mollusks are usually nucleated with spherical bead nuclei (in the hopes that the resulting pearl will be a perfect Round). This round nucleus is inserted into the host mollusk, which then encircles it with a pearl sac.
The A-D System, or Tahitian System
A is the highest grade in this system, with D being the lowest. The A-D system is based on a French Polynesian government standard and sometimes substituted by the AAA-A system in other parts of the world. D: The lowest rating doesn't look at luster but only surface defects.
