Real pearls can be identified by their unique surface, which is often rough or bumpy. They also have a lustre that is more subtle than other gemstones. Additionally, when rubbed against the front teeth, real pearls will feel slightly gritty.
An authentic pearl displays fluoresce under ultraviolet light because of the presence of natural organic compounds in its nacre. On the other hand, fake pearls are typically made out of glass or plastic and don't contain these natural organic compounds. As a result, they won't display fluoresce under UV light.
To try it for yourself, put a drop of vinegar on the pearl or submerge the pearl in a small cup of vinegar. If you can see bubbles forming from the release of carbon dioxide in the chemical reaction, your pearls are authentic.
It's often assumed that because something's old it must be valuable. That's rarely true and certainly not for pearls. Advances in technology and culturing techniques mean you can buy a much better set of pearls for far less money than in grandma's time.
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.
Real pearls are cold to touch for the first couple of seconds before adjusting to your body temperature. Fake plastic pearls will be room temperature to begin with and you won't feel the coolness when you touch them.
Real pearls are normally heavier than the fake ones. Toss them gently up and down in your hand and feel the weight difference. You can use this method to test those made from coated glass or plastic beads. The only exception with this weight test is in the case of solid glass beads.
How Much Are Real Pearls Worth? A traditional strand of white pearls can range from $100 (Freshwater pearl necklace) to $10,000 (Akoya pearl necklace). A strand of large, flawless South Sea pearls could even be valued as high as $100,000+ .
To determine if the necklace is genuine, there are several things you can look for. First, check the lustre of the pearls. Real pearls will have a strong and iridescent shine, while fake pearls may appear dull or cloudy. Also, rub two natural pearls together; they are real if they make a gritty sound.
The value of a pearl can vary dramatically depending on many factors, such as its type, size, color, surface quality, and more. A wild pearl will be worth more than a cultured pearl. However, on average, a pearl's value ranges from $300 to $1500.
Some pearls develop with one or more grooves or rings encircling them. These pearls are known as ringed or circled. The primary shape of a pearl is, therefore, described as circled round or ringed oval.
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.
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.
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 . When wet, the thread that holds the beads together begins to stretch and lengthen, so it quickly loses the desired shape.
Friction Tests:
Hold the pearls in your fingers, and gently rub them against each other. A true pearl will create friction with another due to the grainy, imperfect surface. Fakes, on the other hand, will easily glide past each other due to their artificial coatings.
Don't wear them in the swimming pool
Harmful chemicals such as chlorine in a pool can effect or cloud the lustre of a pearl and in some instances etch or pit the surface. Wearing a strand of pearls in water can also lead the silk thread they are strung with, to stretch.
As with many metals and gemstones, a little scratch can do wonders when it comes to figuring out if a pearl is real. Using the tip of a knife, create a tiny impression in the surface. A real pearl will yield a small amount of dust or powder, while coated beads will reveal the surface of the glass.
The surface of a pearl is soft and is easily damaged. Pearls set in rings and bracelets are more subject to scuffing and scratching than pearls set in brooches, earrings, necklaces or strands.
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.
Hot water can permanently damage your pearls. Do not let your pearls soak in the water. Let the pearls and string dry out for 24 hours before wearing. Never wear your pearls when the string is still wet .
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.
