The Ultimate Guide to Pearls
Deep Diving Into Everything About Pearls
Pearls, the treasures of the sea, are nature’s way of transforming an irritant into something truly exquisite. Formed when a foreign particle—such as a grain of sand or a tiny shell fragment—enters an oyster or mollusk, the creature responds by coating it with layers of a luminous substance called nacre. Over time, these layers build upon one another, creating the smooth, iridescent beauty that has captivated civilizations for centuries.
At My Jewelry Repair, our appreciation for the elegance and mystique of pearls inspired us to create this Ultimate Pearl Guide. Whether you’re looking to purchase your first strand, care for a beloved heirloom, or simply deepen your knowledge, we hope this guide serves as a comprehensive and insightful resource.
What Should We Be Looking For in a Pearl?
Did you know that pearls are probably the most unique of all birthstones and gemstones in general, as they are the only gemstones that are made from a living organism?
Quality Characteristics of Pearls include:
- Luster
- Color
- Shape
- Surface
- Size
The closer a pearl comes to being perfect in these characteristics, the more valuable the pearl.
Types of Pearls
The pearl gemstone comes from many body of waters globally, including oceans, lakes, and rivers. These organic gems grow from the inside the tissue of living creatures either in saltwater or freshwater. These creatures, known as mollusk, could either be an oyster or a mussel, and their pearls are formed from a substance called nacre that is secreted when an irritant, such as sand or a parasite, invades its shell.
There are also two general different types of pearls: natural and cultured.
Natural Pearls
Natural pearls are very rare and extremely expensive, as only one oyster in forty may contain a pearl. A natural pearl is created in the oyster by chance! Natural pearling can be found in the Persian Gulf and the Indian Ocean.
Cultured Pearls
Cultured pearls were developed as a response to the extreme rarity of naturally formed pearls. By seeding an oyster with an irritant, layer upon layer of nacre forms until a lustrous cultured pearl is created. Cultured pearls are frequently bleached and polished for uniform color and shape. Some cultured pearls are dyed or irradiated to achieve to change or enhance the color.
These cultured pearls account for many of the pearls that are on the market today, making natural pearls the rarest, and therefore, the most expensive.
As there are many different environments in which pearls can grow, there is a result of different pearl gemstones in various shapes, colors, and sizes! Pearls can come in colors such as white, silver, yellow, green, blue, brown, pink, purple, and black; because natural black pearls are so rare, these are mostly cultured.
Akoya and Freshwater
The 2 most common types of pearls are Akoya Cultured Pearls and Freshwater Cultured Pearls.
- Akoya Cultured Pearls are cultured in saltwater. Japan is known to produce the highest quality Akoya cultured pearls. They tend to be more expensive than Freshwater cultured pearls since they are less available.
- Freshwater Cultured Pearls are cultured in rivers and lakes primarily in China, They are less expensive than the Akoya cultured pearls since they are more readily available.
A Brief History and Symbolism of Pearls
Cultural Significance: Rubies in Lore and Legend
The English name of this gemstone “pearl” comes from the French word “perle,” which was originally derived from the Latin word “perna.” This Latin word means “leg,” which is referencing the shape of an open mollusk shell.
But did you also know that the scientific name for the pearl-bearing oysters is “Margaritiferidae,” which comes from “margarita,” which is the Old Persian word for pearl? If your name is Margaret, then this is where your name stems from!
As previously mentioned, natural pearls are very rare and extremely valuable, as only one of forty oysters produces a pearl in the natural process. Therefore, in 1893, Kokichi Mikimoto, invented a viable technique for producing hemispherical “cultured pearls” in Japan. Mikimoto helped advance the science of pearl cultivation and has remained synonymous with harnessing the allure of pearls for more than 120 years.
Throughout this time, Mikimoto has become the world’s foremost producer of fine cultured pearls, not to mention a global leader in exceptional jewelry design incorporating these top-shelf gems of the sea.
Pro Tip: If someone happens to be selling a Mikimoto piece, make sure that they have a certificate of authenticity.
These beautiful gemstones are known to symbolize wisdom, integrity, purity, loyalty, and serenity. In ancient times, they were also associated with healing properties to promote serenity, protection, security, confidence, and enlightenment, which ties in very similarly to its current symbolism. Pearl gemstones were a sign of high status and wealth in ancient Rome, and were used as protective amulets by some knights during the crusades.
Pearls have a hardness of 2.5 to 3.0 on the Mohs scale of hardness. To put this in perspective, quartz has a hardness of 7 – 7.5 and are present in the particles of dust seen floating in the air and settling on uncleaned objects in your home. These particles have the hardness that is able to remove the polish from your table and the finish from your car. Diamonds have a hardness of 10, which is the hardest gemstone, and the softest includes talc, which is a gemstone that even your fingernail can scratch.
These minerals can only be scratched by the hardness level above it, so pearls most definitely need special care and maintenance to keep it looking as pretty as possible.

How to Properly Care for Pearl Jewelry
Keeping the Sparkle and Brilliance
Thinking about restoring a loved one’s sentimental birthstone piece? You’re in the right place to restore their precious memories.
It is recommended to have your pearls serviced and restrung by professional and experienced jewelers, just like the ones that we have here at My Jewelry Repair. However, in order to have your pearls looking as good as possible on a daily basis, there are several steps that you need to consider while caring and maintaining your pearl jewelry.
Pearl Jewelry Care and Maintenance
Proper care for your pearls is very important since they are an organic gemstone that is vulnerable to acid, alkaline and extremes of humidity. To protect your pearls and preserve their luster, avoid contact with cosmetics, hair spray, or perfume.
Always put on your pearls as a final touch, after applying cosmetics, perfumes, and hair spray. Pearls can also be damaged by perspiration, so always wipe them with a soft damp cloth before storing them.
Pearls also have a soft surface, and can easily be scratched. Store them away from other jewelry and use a protective jewelry pouch when carrying them. Pearl strands should be restrung as part of the basic care and maintenance, the frequency depends on how often they are worn.
