Real or imitation pearls?

Pearls have fascinated people for centuries with their soft glow, elegance, and timeless beauty. Today, pearls are more popular than ever — from classic strands to modern pearl jewelry designs.

However, still, people don't know much about pearls.  There is one question I hear very often from clients who come to my showroom: "Are my pearls real or imitation? I don't know the difference between real and imitation pearls."

Many of us inherit pearl jewelry from a family member, receive a pearl necklace as a gift, or discover an old piece of pearl jewelry.  And they simply do not know what they have. At first glance, imitation pearls and real pearls can sometimes look very similar, especially to someone who is not familiar with this gemstone.

 As a gemologist and jewelry appraiser, I regularly examine pearl jewelry brought in by customers willing to know whether their pearls are genuine, what type of pearls they have, and whether their jewelry has value.

The answer is not always as simple as it seems.

Today’s pearl market includes different types of pearls. Some are natural pearls created entirely by nature, some are cultured pearls created with human assistance, and others are imitations made to resemble pearls.

Understanding the difference is important — not only because of value, but also because of quality, durability, and the story behind your jewelry.

To make it easier for consumers, let's classify pearls.  The first and the most important question is whether pearls are real or imitation.  Actually, this is the major factor affecting pearls' value.

 What Are  Real or Genuine Pearls?

A genuine pearl is made by a living organism, a mollusk. Whether it is a natural pearl or a cultured one, it is composed of layers of nacre, a beautiful material that gives pearls their unique glow and depth.

What Are Imitation Pearls?

On the other hand, imitation or fake pearls are man-made beads looking like genuine pearls.

Imitation pearls may be called differently - “faux”, “simulated”, “semi-cultured”, "man-made", or even “organic”.

They are often made of glass, plastic, or shell beads covered by ground fish scale and lacquer (called "pearlessence"). Or it may be new plastic substances.

A Little History: an Imitation or Fake Pearl Is Nothing New

As throughout history pearls have been extremely rare and valuable, for centuries, people were trying to imitate the beauty of natural pearls.  

Even Leonardo da Vinci was offering his recipe for imitation pearls!

Eventually, the recipe for the contemporary imitation pearls was found in the 17th century in France by a rosary-bead maker named Jacquin.  Putting fish scale in a basin of water, he noticed that the water got unusual colorful pearly reflections. 

Then, Jacquin filtered the water, separated this pearly substance, and mixed it with a kind of varnish.  Finally, he took a hollow glass bead and covered its inside walls with this substance.  Voila!  He got an imitation pearl!

What are natural pearls?

Natural pearls form completely naturally, without human intervention.  An irritant (a microorganism, a worm, etc.) enters a mollusk.  As a response, the mollusk creates layers of nacre around it. 

Due to many reasons natural pearls are extremely rare today.  Natural pearls have significant value, especially when they have exceptional size, shape, color, and history.

What are cultured pearls?

 

Cultured pearls are also real pearls. The difference is that the process of nacre formation is triggered by man - an irritant (a piece of mantle or a bead with a piece of mantle) is carefully inserted into the mollusk.  As a response to irritation, the mollusk creates nacre layers around it.

Each real pearl develops layers of nacre, giving it depth, luster, and a unique glow that imitation pearls cannot fully copy.

Up to 99% of pearls in the market today are cultured pearls (both freshwater and saltwater ones).  But an important factor is that the pearl itself is formed naturally, by the mollusk.

Why Do Imitation Pearls Look Like Real Pearls?

Imitation pearls are designed to reproduce visual qualities of genuine pearls, e.g. luster and soft reflections.

While a real pearl develops its beautiful memorable appearance through layers of nacre, as a result of staying in the living organism, a mollusk.  On the contrary, an imitation pearl is man-made.  

Modern coatings can contain very fine particles or materials that reflect and scatter light in ways that imitate the nacre appearance. Multiple layers may be applied to create greater depth and a more natural-looking luster.

And the result can be surprisingly convincing. A high-quality fake pearl may possess an attractive glow, beautiful color, and even subtle variations that make it appear very similar to a cultured pearl.

But appearance alone does not make an imitation pearl a real pearl. The essential difference lies beneath the surface: a real pearl consists of layers of nacre created by the inside of the mollusk, while an imitation pearl has never seen the inside of the mollusk, it has a manufactured core and coating.

Some imitation pearls can look convincing at first glance, especially in photos or under artificial lighting.   Sometime, when someone sends a photo asking to tell whether the pearl jewelry features real pearls or imitation, it is difficult to determine the nature of the pearl judging the photo.

Some imitations are easy to recognize, while others can be difficult to distinguish from real pearls without closer examination.

Why Knowing the Difference Matters When Buying Jewelry

 Knowing whether a pearl is real or imitation matters because appearance alone does not tell you what you are buying.

Real pearls, whether natural or cultured, are formed through a biological process and consist largely of nacre. Imitation pearls are manufactured from other materials and are designed to look like pearls. The difference affects their value, durability, care, and price.

There is nothing bad in buying and wearing imitation pearls.  However, you should know their nature as they have different value. Thus, you should know the difference between the two to be sure what you are paying for.

An imitation pearl can be beautiful and perfectly suitable for fashion jewelry, but it should not be presented or priced as a cultured or natural pearl.

This is particularly important when buying vintage or inherited jewelry, where the origin and nature of the pearls may not be immediately obvious. A knowledgeable jeweler or gemologist can help establish what you actually have.

Final Thoughts

Pearls are one of the few gems created by living organisms, which makes them truly exceptional. Whether classic white pearls, modern baroque pearls, or luminous keshi pearls, genuine pearls possess depth and character that imitation versions simply cannot imitate completely.

When purchasing pearl jewelry, it is always worth buying from a trusted jeweler or gemologist who can explain the quality, origin, and characteristics of the pearls.
