Yes, real pearls have scratches because they are relatively soft (around 3.5-4 on the Mohs scale) and made of layered nacre, which can abrade from contact with harder surfaces, grit, or even other pearls, leading to minor blemishes or dullness over time, although high-quality pearls have fewer and less noticeable imperfections. Fake pearls, in contrast, often have a perfectly smooth coating that might chip or peel, revealing the base material underneath, whereas real pearls develop natural growth marks, pits, or subtle abrasions.
Pearl is ranked 2.5 on the Mohs hardness scale, which means it's very soft and easily scratched or abraded. But with reasonable care, pearl jewelry can be a lasting treasure.
Pearls aren't like hard gemstones where you can buff out scratches and make them “new” again. Their shine comes from multiple delicate outer layers of nacre. Once the layers are worn down, their lustre can't be fully restored.
Pearls can chip and scratch each other if not knotted. You may not have realized your pearls are knotted because, if done well, the knots are small and uniform. This becomes even more true when you are talking about fine, higher end pearls.
The sad reality is that old, second-hand cultured pearls aren't worth a lot. There's no obvious place to sell them and you won't get much from a jeweller or by putting them on eBay. Our advice is to keep them as a memento or give them to someone who'll appreciate them.
Microscopic Analysis. A jeweler may also use a microscope to examine the pearl's surface and internal structure. Under magnification, the natural crystalline structure of nacre is visible in real pearls, while fake pearls will lack this texture.
In water, pearls do not float.
Pearls are incredibly soft. They have a delicate structure and can be scratched and damaged easily.
It was Jackie Kennedy who said 'pearls are always appropriate,' meaning that they suit all occasions and all outfits. Indeed pearls are still worn by many brides on their wedding days and feature in most jewellers' windows today.
How To Tell If Pearls Are Real
Imitation pearls might have a magnetic core, but genuine pearls are made from organic material that does not respond to magnets.
Pearls can age because they are made of biological materials. They might lose their shine, peel, or break down over time. Pearl jewelry, on the other hand, can keep its beauty and shape for hundreds of years if it is stored and cared for properly. Wearing pearl jewelry is probably the best way to keep it in good shape.
Pearl earrings can get wet occasionally, but they don't like it. Repeated exposure to water will shorten their life and dull their shine. Pearls are organic gemstones made from layers of nacre. That nacre is both delicate and slightly porous.
The trick is that when you rub real pearls together, there is some friction and a tiny amount of nacre will rub off, leaving a fine powder. If you rub together two fake pearls, they'll just slide against each other smoothly. The difference is pretty obvious when you rub a pearl against your teeth.
Pearls are counted by hand and then weighed with an electronic micro-balance that captures the weight in grams (mounted or strung), carats (loose), or carats and grains (loose natural). Pearls are measured using special digital calipers.
Cultured pearls exhibit a fluorescent glow due to the materials used in their creation, while natural pearls generally show no reaction under UV light. Purity Testing: Cultured pearls, due to their controlled formation process, often have different impurity levels compared to natural pearls.
Pearl jewellery and pearls are not traded like gold or silver. 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.
The most expensive pearl colors are often deep, rich hues like Golden South Sea (especially 24k deep gold), rare Peacock Tahitian (dark green/blue/purple overtones), and intensely pink or pink-overtoned White South Sea pearls, with value heavily depending on rarity, luster, size, and lack of blemishes, rather than just the base color itself. While white and black are common, specific, saturated, and rare overtones within these categories command the highest prices.
Generally, you can expect to pay anywhere from $100 to $200 for a professional appraisal. Insurance appraisals are generally more expensive because they must be done by a certified gemologist and include a more detailed report.
Although fake pearls are typically very smooth and artificially perfect, a real pearl may often have irregularities such as pits, chips, bumps and scratches on its surface.
Experts warn that moisture can seep into the pearls' porous nacre, weakening their structure, causing layers to swell or separate, and quickly dulling their natural luster. Even routine activities like showering or washing hands can expose pearls to minerals and proteins that may stain or damage their surface.
Pearls age and turn colors when their organic materials dry out. Once pearls have yellowed, you can't usually correct their color by cleaning. To prevent your pearls from drying out and yellowing, wear them often and don't store them in air-tight containers.
