Pearls have held significant cultural, historical, and economic importance throughout human history. Here’s some information about real pearls from their historical significance to their presence in modern times:

1. Ancient History: Pearls have been treasured for thousands of years, with evidence of their use dating back to ancient civilizations in Mesopotamia, Egypt, and India. The ancient Egyptians were particularly fond of pearls, and they were often associated with royalty and wealth.
2. The Roman Empire: Pearls were highly valued during the Roman Empire, and wealthy Romans would adorn themselves with pearl jewelry as a symbol of status and prestige. The historian Pliny the Elder wrote extensively about pearls in his work “Natural History.”
3. The Middle Ages: During the Middle Ages, pearls continued to be a symbol of wealth and nobility. They were sought after for use in religious objects, crowns, and garments worn by the elite.
4. The Age of Exploration: In the 15th and 16th centuries, explorers from Europe sought to discover new lands and trade routes, leading to increased contact with regions where pearls were abundant. Pearls from the Americas, particularly from the Gulf of Mexico, became highly prized and were often sent to Europe as valuable commodities.
5. The Pearl Rush: In the 19th century, the discovery of pearls in various regions, such as the Persian Gulf and Australia, led to a “pearl rush,” with people flocking to these areas to find pearls and make their fortune. However, the demand for natural pearls also led to overfishing and the depletion of pearl oyster populations.
6. The Rise of Cultured Pearls: In the early 20th century, Kokichi Mikimoto, a Japanese entrepreneur, successfully developed the technique of culturing pearls by inserting a nucleus into oysters, encouraging the growth of pearls. This revolutionized the pearl industry and made pearls more accessible to a broader market.
7. Modern Pearls: Today, cultured pearls dominate the market, with freshwater and saltwater pearls being the most common types. Cultured pearls can be found in various shapes, sizes, and colors, making them more versatile and affordable compared to natural pearls.
8. Famous Pearls: Throughout history, several famous pearls have gained legendary status. Some notable examples include La Peregrina (discovered in the 16th century and owned by various European monarchs and celebrities), Hope Pearl (owned by British banker Henry Philip Hope), and the Arco Valley Pearl (one of the largest natural pearls ever discovered).
9. Symbolism and Jewelry: Pearls continue to be associated with purity, elegance, and femininity. They are often used in jewelry, especially in necklaces, earrings, bracelets, and rings. Pearls are also popular choices for weddings and formal occasions.
10. Conservation Efforts: Due to overfishing and habitat destruction, some species of pearl-producing oysters have become endangered. As a result, there have been conservation efforts to protect these marine ecosystems and ensure the sustainability of pearl production.

Types of Saltwater Pearls

Saltwater pearls come from oysters and mussels in oceans, seas, gulfs and bays. They are usually high-quality and more expensive than freshwater pearls. Freshwater pearls are found in mollusks and rivers, lakes and ponds.

Akoya Pearls

Akoya pearls are the preeminent cultured pearls. They are the pearls that the Mikimoto brand popularized. Prized by royalty and pearl connoisseurs for centuries, Akoya pearls have long been coveted for their perfectly round shape, richness, and deep luster. The natural body colors range from light pink to white to pale yellow, and include green and blue gray tones. Akoya pearls are normally associated with Japan, especially if they measure over 7 mm. China, Korea, Hong Kong, Vietnam, and Sri Lanka all produce Akoya pearls in smaller sizes. Some of the most well-known and highly valuable pearls come from a group of marine bivalves called pearl oysters from the family Pinctada and Pteria.

South Sea and Tahitian Pearls

These pearls are cultured in the large muscle Pinctada maxima and usually require a longer growing time in the shell than do Akoya pearls. They can be white with a rose or green tint, green, blue- gray, golden or pale yellow in color. The luster and light colored South Sea pearls tend to be less intense than the dark pearls. Vibrant, golden-colored South Sea pearls are very popular and command a high price as does the white rose color. South Sea pearls are the largest cultured pearls of all and – as their size increases – so does the price. Round pearls are the rarest and most expensive shape. Black Tahitian pearls from the black-lip mussel Pinctada margaritifera are the only natural black pearls that exist; all other black pearls are dyed. The black color can vary from silver to dark gray and may have pink and green overtones. Black pearls can look almost metallic.

Keshi Pearls

Keshi are tiny pearls that form spontaneously when a much larger nucleated pearl is cultured in the Akoya oyster. Keshi is the Japanese name for “poppy”, referring to tiny natural seed pearls. Originally these natural seed pearls were found in Kobe in Japan, when harvesting wild Akoya oysters. As keshi grow without a nucleus they are in effect natural pearls. They have the same coloring as Akoya pearls. Keshi pearls always have good luster and often an unusual palette of colors like eggplant, vivid purple with green overtones, bronze, peacock with vivid green, and green with purple overtones, pistachio and silver-gray. Any unused Keshi are sold to India and China for medicinal and calcium content.

Types of Freshwater Pearls

Lake Biwa is Japan’s largest lake and was the first freshwater culturing site. Biwa pearls are noted for their good quality surface and nice luster. They don’t normally have a nucleus as the mussel won’t accept one, and – as a result – some bizarre shapes can occur. The colors range from creamy white to white-rose, salmon orange, dark wine red and violet. Many freshwater pearls on the market are called Biwa pearls, despite being cultivated in China. This is most likely done to impress or reassure customers, and to garner higher prices.

Chinese Freshwater Pearls

Chinese freshwater pearls are a popular type of cultured pearl. They are unique because they are nucleated with a small piece of mantle tissue from another oyster. There are over 350 species of freshwater mussels residing in lakes, rivers and streams. Several species have more recently become extinct due to water pollution and over-development of surrounding lands. However, the Chinese have managed to successfully produce an abundance especially of cultured freshwater pearls using the pearl mussel Hyriopsis cumingii providing an economic staple of the cultured pearl business. The colors are wide-ranging, but include rose, white, green-white, green-rose, salmon orange, wine red and violet.

Mabe Pearls

Mabe pearls are cultured by gluing a half-bead nucleus against the inside of the shell. When the hemisphere pearl is covered in nacre, it is cut out. The nucleus is removed, and the hole is then filled. The pearl is then backed with mother-of-pearl. Because mabe pearls are constructed, they are not as durable as other types of pearls, and over time the nacre coating can either lift off, become damaged, or sometimes discolor. If a mabe has a rim around it, making it look like a fried egg, it is called a “blister mabe”.

Blister Pearls

These pearls grow attached to the inner surface of the shell rather than loose in the mantle. They have the same iridescent nacre as the inner surface of the shell, and the back is flat, without any pearly coating.

Seed Pearls

Seed pearls are small natural pearls that measure 2mm or less.

Overall, pearls have left an indelible mark on human history, from being a symbol of wealth and royalty to becoming a staple of modern jewelry and fashion. Their allure and beauty continue to captivate people worldwide, making them a timeless and cherished gem.
