An easy way to determine whether a pearl is real is to look at the surface; authentic pearls will have some slight irregularities and bumps that make them unique. For example, if you rub the pearl against your teeth, a real one will feel gritty, while a fake one will feel smooth.
Look for tiny irregularities
In a strand of cultured pearls, you can always see very tiny differences between them, even when they are top quality and well matched. If the pearls are completely perfect and identical in terms of shape, size, colour and surface characteristics, they are probably fake.
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.
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.
Under a black light, faux pearls will often emit a consistent milky, bluish-white glow. This uniformity in color is a key indicator that the pearls are not authentic. On the other hand, real pearls will exhibit variations in color intensity from pearl to pearl when viewed under a black light.
(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.
Pearls with particular brand names will also retain (and even increase) their value over the years; vintage Mikimoto Akoya pearls that still have their original clasp, box and papers to establish provenance are very highly sought after today and continue to fetch premium resale values.
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.
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.
Synthetic pearls are usually either coated plastic, glass or crystal beads, and generally are visually perfect with very little to no variation in shape, size, luster or color/overtone.
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.
Freshwater pearls have no core and are made up entirely of mother-of-pearl – so 98% of these stones are not round but oval, buttoned, drop or baroque in shape. Freshwater pearls are cheaper because they are easier to extract, making sea pearls more valued.
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.
Genuine pearls are shinier than fake pearls. You can measure shine in luster, which is the intensity and softness of a pearl's surface, it generally has to do with how bright and clear a pearl looks. Natural pearls have more shine than artificial ones because they're made from natural materials.
Not just because of the unique color, size, shape, and place of origin, but also accounting for the fact that these gems are made by living oysters. The price of a pearl now averages between $300-1,500, and there are a few factors to consider when questioning both quality and value.
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.
They are considered elite gemstones and do not have a high resale value, at least as of now. Used pearl jewellery, which is sold for higher prices, is usually that which has been worn by celebrities, queens or antique pieces.
*Pearls deteriorate over time, and even with proper care, the smaller ones generally last 150 to 200 years (depending on the thickness of that nacre)... but in 2012, scientists found a single pearl in a gravesite overseas, that was dated at 7500 years old.
Should You Wear Pearls Every Day? There's a straightforward answer to this question. It's really up to you and what you're comfortable with. If you're someone who takes very good care of their belongings and is cautious with how you handle them, then wearing your pearls every day shouldn't be a problem.
Worn often and properly cared for, pearls can look as good in 50 years as they did the day they left the store. Pearls are not the most durable of gems. Most everyday items at home and in the office are tougher than pearls, so careless contact can cause damage them over time. Chemicals are the primary threat.
