Nacre (/ˈne?k?r/ NAY-k?r also /ˈnækr?/ NAK-r?), also known as mother of pearl, is an organic–inorganic composite material produced by some molluscs as an inner shell layer; it is also the material of which pearls are composed. It is strong, resilient, and iridescent.
High quality pearls will have a strong, bright and clear luster and will shine, almost like the light is coming from within, when light hits them. With lustrous pearls, you can usually see your own reflection.
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.

"Pearls," he said, "must be worn frequently to preserve them. If you take a pearl necklace and lock it up you will find that in the course of years the pearls become dull and lose the sheen that makes them so valuable.
It is true that pearls are not as strong as, say, diamonds, making the risk of damage higher if they're worn every day. But with proper care and caution, you can keep your pearls safe, even during everyday wear. This means keeping them away from cosmetics and acidic materials and storing them safely.
Tahitian pearls are the only pearls that have a full color spectrum. Because Tahitian pearls are bead nucleated many of them are round, or near round, with other shapes expressed in drops, baroques, button and circled pearls. When all other factors are equal, round Tahitian pearls are the most valuable.
This question came to me after reading the "Vintage Mikimoto Pearl" thread. Pearls are only worth what you can sell them for. Generally there is no, or very little pawn value, unlike gold jewelry. Miki's retain value based on the condition of the pearls, having the original clasp, box and paperwork.
The value of a pearl can vary dramatically depending on many factors, such as pearl type, size, color, surface quality, and more. A wild pearl will be worth more than a cultured pearl. To keep it short, on average, a pearl's value ranges from $300 to $1500.
Mix a solution of lukewarm water and a few drops of mild detergent or dish soap. Water that is too hot or too cold may damage the surface of the pearls, so double-check the temperature before using it on the jewelry. Dip a soft, clean cloth into the water and gently wipe down the pearls.
Wear Your Pearls OftenIf your pearls dry out this causes them to become brittle and the risk of them becoming damaged or they start to peel will increase. So it is important that you wear your pearls as often as you can. Leaving them tucked away in an airtight bag or safe will do them more harm than good.
Pearls are incredibly delicate products of nature. As a strict guideline, you should never shower with your pearls on and always wipe them gently after wearing with a soft cloth.
Why? Well, bleaching is a great way to clean and brighten the pearl surface and it lends a more uniform look to pearls. This becomes important when matching pearls in a strand or bracelet.
Clean with a damp cloth only as needed.If your pearls are visibly stained, you can mix a solution of lukewarm water and mild dish soap, dip a soft cleaning cloth in it and wipe the pearls. Do NOT submerge a pearl necklace in water, as it will weaken the silk thread.
Like many things in life, pearls age. As these precious gems age, they go through a natural process that changes the composition of the organic substances that make them up. This causes them to change color. Yellow pearls typically indicate that pearls are real since artificial pearls don't normally change color.
Keep pearls away from chlorine bleach, hydrogen peroxide, vinegar, ammonia, hairspray, perfume, and cosmetics, as these substances will damage the pearl surface. Make sure to put pearls on after finished spraying perfume or hairspray and putting on makeup.
Luster is what gives a natural or cultured pearl its unique beauty. Within a pearl type, when other value factors are equal, the higher the luster, the more valuable the pearl. From top to bottom, these Japanese saltwater cultured pearls show excellent, very good, good, fair, and poor luster.
Humid environments, such as the bathroom or a room with a portable humidifier, are highly recommended for keeping mother of pearl jewelry. Otherwise, it will dry out and lose its natural allure.
Can You Repair a Damaged Pearl? Once the integrity of a pearl's surface or internal structure has been compromised, there is no way to repair the damage. If your pearl is chipped, the only solution is to buy a new one. Pearls are very vulnerable, and you should take extra care to protect them from damage.
Real Pearls Will Not Burn In FireA pearl will not burn or scorch. It also won't give off much of a smell. However, if the imitation pearl is made from glass, wax or plastic, you'll see a scorch mark and it will smell like burning plastic.
You can wash pearls in warm, soapy water, but it's important to use a mild detergent. Add 1 teaspoon (5 ml) of soap to 1 quart (946 ml) of warm water to dilute it, and mix well to create a soapy solution. Ensure that the water is warm and not hot because it can damage the pearls, especially if they are real.
If an oyster that typically produces white pearls has an unusual black coloring in its nacre, it too can create a blackish pearl. This, however, is rare; it occurs in only one in 10,000 pearls. Got a question?
The Tooth Test: Simply rub the pearl against your tooth, softly. If the pearl is natural or cultured, you will feel the surface as gritty. If the pearl is a faux gem, then the surface will feel smooth. FACT: While observing pearls under a magnifier, specialists can easily tell whether they are a fake or a real gem.
You can do the “Tooth Test” by gently sliding the pearl across the front of your teeth. Depending on how you feel its surface, you will know if it is true or fake. Pearl size: South Sea pearls are large in size, so they go best with necklaces.
Also known as the “black pearls” or “black South Sea pearl”, they are grown in the black-lipped oyster called Pinctada margaritifera cumingii, and are indigenous to French Polynesia, Fiji, the Sea of Cortez and the Cook Islands. Typical Price Range: Low: below US$200. Average: US$200 – US$600.
Ideally, pearls should be gently wiped with a soft cotton cloth or a piece of chamois leather after wearing to enhance their natural luster. These gemstones are alkaline. Therefore, contact with any acids such as hairspray, cosmetics, perfumes and fake tan can damage them.
