Most of the pearls have some blemish. It can be said blemishes act as additional evidence of a pearl's authenticity. During the process to farm peals, wrinkles, dents, and protrusion are formed on the surface and called “Blemish.” There are no criteria how to define Blemish.
Real Pearls Have Imperfections
The vast majority of pearls are not perfect. There is almost always an imperfection such as an issue with the shape, a slight indentation or slightly off color to it (even if ever so slight).
Usually they will have slight imperfections, small blemishes or an irregular shape. The outer layer of the pearl, or the nacre, will reflect light differently as the pearl is turned. Conversely, imitation pearls are usually too "perfect." They will be perfectly round and the surface will show no imperfections.
Common Freshwater Pearl Blemishes
Chalky spots are easily the most common of Freshwater pearl inclusions. They're exactly what they sound like: dull, chalky-looking areas on the pearl surface. Pits or pitting blemishes are similar to pin-prick inclusions found on saltwater cultured pearls.
It's important to remember that some blemishes won't detract from the beauty or value of a pearl, and this is particularly true with South Sea pearls. That's because it takes these pearls 2 to 3 years to develop, and flawless or slightly flawed South Sea pearls are extremely rare.
South Sea pearls are generally much larger than other pearl types and have a unique luster quality – a soft reflection due to the large aragonite platelets that make up the pearl. They also have the thickest average nacre of all cultured pearls. These factors make South Seas both distinctive and valuable.
Wetting pearls is never a good idea, as it begins to destroy the jewel. Pearl necklaces are damaged when they get wet, because the water damages both the thread and the pearl .
this might be a dark spot or hole where either there is a black spot and a lack of nacre. These black spots appear to be some sort of "dead" spot. They are a sign of no nacre, poor nacre development, some sort of occlusion or a place where the pearl did not develop well.
Freshwater pearls are cheaper because they are easier to extract, making sea pearls more valued. Why? Sea pearls are larger, more beautiful in shape, luster, smoother surface and, of course, much more expensive than freshwater pearls.
Do pearls lose their luster or become dull? It's possible that pearls can lose their shimmer and shine over time, but you can prevent it from happening by learning how to clean your cultured pearl necklaces, bracelets, rings and earrings.
Natural pearls are rarely circular. Their surface is neither perfect nor smooth throughout, but rather rough and uneven.
Pearls are naturally not as smooth and may contain some imperfections in their surfaces, such as tiny scratches, spots of colors, or bumps called “pearling.” The more perfect the pearl, the less likely it is to be real. Additionally, fake pearls will often have a rough, chalky texture with visible flaws on the surface.
Pearl is generally stable to light, but heat from intense light can cause dehydration and cracked nacre. Pearl can be damaged by many chemicals and all acids. The list includes hair spray, perfume, cosmetics and even perspiration. Pearls might be dyed, impregnated or coated.
Dents or divots are pearl blemishes that are easily seen with the naked eye. They can differ in depth and shallowness, and they can either match the color of a pearl or have a greyish/brownish tone.
Though pearls carry a low rating on the Mohs scale, and can be easily scratched with harder materials, their softness does not equate to weakness.
Black pearls are formed when that piece of sand gets stuck in the body of a very specific type of oyster, the Tahitian black-lipped Pinctada margaritifera. The interior shell, called the nacre, of most oysters is usually a glossy white or silver but the Tahitian black-lipped oyster features a thick band of black.
Looking closely, you'll see small ridges on real pearls resembling fingerprints. These ridges give each pearl its unique character and make authentic pearls slightly rough to the touch. Therefore, if you can't feel the ridges on the surface of "real" pearls because they're completely smooth, they probably aren't real.
Under a black light cultured pearls usually have a milky, bluish-white look to them, plus there will be a uniformity in color of cultured pearls in a necklace. Natural pearls in a strand will have variations in color intensity from pearl to pearl and will usually appear tan or yellowish under a black light.
Is it OK to wear pearls everyday? Absolutely. Pearl jewelry should be worn and enjoyed frequently, so avoid leaving your pearls in a security box for long periods of time. But as many jewelry, pearls are beautiful, but they are delicate and should be worn with care.
Astrology says that the people whose zodiac signs lords are Mercury, Venus, Saturn and Rahu should never wear pearls. Pearls harm the natives of these zodiac signs. This means that people of Taurus, Gemini, Virgo, Capricorn and Aquarius ascendant should not wear pearls.
No, pearls aren't vegan. Oysters and other mollusks only produce pearls as a response to a stressful environment, and it's speciesist to torment and kill an animal just because we think the end result is beautiful.
Yes… Cultured pearls are real pearls grown inside real oysters at pearl farms in Japan, Australia, Indonesia, China and many more locations. Natural or wild pearls are typically found by shellfish harvesters purely by accident. You might have to open 10,000 oysters to find a single decent quality natural pearl.
South Sea pearls are produced inside the Pinctada maxima mollusk, found throughout the Indian and Pacific Oceans. They are cultivated primarily in Australia, Indonesia, the Philippines, and Myanmar. Edison pearls are freshwater pearls produced inside mussels. They are cultivated primarily in China.
Fine South Sea Baroque Pearls are much more valuable and desirable than Baroque Akoya Pearls. Because of the large size difference in the two primary varieties, a South Sea Baroque Pearl is more likely to have a critical mass of lustrous surface.
