Even with a photograph.
What does a real pearl necklace look like.
Real pearls have like a fingerprint like surface ridges in them so they are not identical or perfectly spherical.
A pearl is a hard glistening object produced within the soft tissue specifically the mantle of a living shelled mollusk or another animal such as fossil conulariids just like the shell of a mollusk a pearl is composed of calcium carbonate mainly aragonite or a mixture of aragonite and calcite in minute crystalline form which has deposited in concentric layers.
Examining pearls by feel.
If you notice any paint is missing or if the material from inside the pearl formed a burr when the pearl was drilled your pearls are probably fake.
A real pearl will have well defined edges like a hollow cylinder.
Real pearls will have a drill hole that is quite smooth and doesn t show any chipping unless it has been mishandled.
Examine the drill hole with a magnifying glass.
Pearls on a strand or necklace will usually have holes drilled in them for the string to pass through.
If you look very closely at them even under a magnifying glass you will notice these surface ridges and the specific quality to each pearl whereas fake pearls they all of them look identical and have smooth surfaces.
But there are clues.
Pearl size get out your ruler and measure the diameter of the largest pearls on the necklace.
Examining this hole carefully can help you tell whether your pearl is real or not.
Look for clues around the drill hole.
Even so the setting can provide clues to help you reach a conclusion.
Are they real pearls.
A string of pearls is likely fake if every pearl appears like a tiny ball.
From a description alone it s not possible to say with certainty whether a necklace is real or imitation.
Also look for chipped paint or coating around the hole.
In a finished necklace or bracelet real pearls are more likely than faux to have knots between each pearl.
Some fakes have high quality settings and some genuine pearls have cheap settings.
If you place a natural pearl against a dark background like a box lined in black cloth and put it under a strong light the natural pearl will look like a small white homogenous ball with no discernible inner rings.
Not every pearl will be the same size.
Real pearls are formed by nature and will always have some sort of imperfection if you look close enough.
Real pearls are more likely to have settings of gold silver or platinum.
Method 2 of 3.
One thing you can do to determine if a pearl is real or fake is to detect the weight.
Real pearls will often show evidence of a nucleus.
Look around the pearl drill hole.
In the 1950 s 60 s and 70 s a typical size for cultured pearls was 4mm to 6mm.
You may not be able to hold the pearls alone.
To find it look carefully between two pearls at a drill hole.
Real pearls are made by nature so there should be some variation in size.
Pearls strung along a strand will have holes drilled for the silk string to pass through.
Imitation or simulated pearls often have rough or rounded edges.
