Types of Pearls: How to Choose & Maintain Your Jewelry
Published: 1 Mar 2025
Pearls have been cherished for centuries for their timeless elegance and natural beauty. Whether you’re looking for a classic piece or something more unique, there’s a pearl type to suit every style and occasion.
In this guide, we’ll explore the different types of pearls available and explain the key differences between natural and cultured pearls. By the end, you’ll be equipped with all the information you need to choose the perfect pearl for your jewelry collection.
What Are Pearls?
Pearls are beautiful, natural gemstones that form inside mollusks like oysters and mussels. They start forming when something small, like a grain of sand or a tiny parasite, gets inside the mollusk. The mollusk then covers it with layers of nacre, which gives pearls their shine and smooth feel.
Types of Pearls
Pearls are available in many types, each with unique features and characteristics. Whether you’re looking for a classic, bold, or artistic design, there’s a pearl to match your style. Let’s explore the different types of pearls, each with its own qualities.
Akoya Pearls:
Akoya pearls are small, round pearls known for their high shine and smooth surface. They’re typically white or cream, making them a classic choice for elegant jewelry. These pearls have a thin to medium nacre thickness, giving them a bright luster. Akoya pearls are most commonly used in necklaces, earrings, and bracelets, making them a staple in classic jewelry designs. They are primarily found in Japan and China, where they are cultured using a small bead inside the mollusk.
South Sea Pearls:
South Sea pearls are larger and considered luxury pearls due to their size and stunning appearance. They come in a range of colors, from white and silver to gold. With a thick nacre layer, these pearls are known for their rich, lustrous shine. South Sea pearls are ideal for high-end, statement jewelry pieces such as necklaces and rings. They are cultured mainly in Australia, the Philippines, and Indonesia, and the process typically involves a bead nucleus to encourage growth.
Tahitian Pearls:
Tahitian pearls, also known as “black pearls,” are famous for their striking dark colors, ranging from deep blacks to shades of gray, green, and blue, with an iridescent sheen. These pearls have a medium to thick nacre layer, which adds to their bold and dramatic look. Tahitian pearls are perfect for making a statement, often used in pendants and earrings. They are primarily found in French Polynesia and are cultured with a bead, usually larger than the one used for Akoya pearls.
Freshwater Pearls:
Freshwater pearls are the most affordable type, formed in freshwater mussels. These pearls come in a variety of colors, including white, pink, peach, and lavender. They are known for their versatility, as they can come in both round and irregular shapes. Freshwater pearls have a thick nacre layer, which gives them a smooth surface and a beautiful luster. They are commonly used in everyday jewelry, such as necklaces and earrings, and are cultured primarily in China.
Keshi Pearls:
Keshi pearls are by-products of the culturing process, often irregularly shaped and small. They are prized for their intense luster and unique, artistic appeal. Keshi pearls have a thick nacre layer, which gives them a bright shine, and each one is unique due to its irregular shape. These pearls are perfect for designer jewelry and one-of-a-kind pieces. Keshi pearls can form in both saltwater and freshwater mollusks, and they occur when the bead nucleus is rejected, leaving only the nacre to form the pearl.
Mabe Pearls:
Mabe pearls are semi-spherical with one flat side, which makes them ideal for use in large jewelry designs such as earrings and rings. These pearls have a medium to thick nacre layer, giving them a lovely luster. Mabe pearls are cultivated in a similar way to other pearls, but a hemisphere is placed inside the mollusk to form them. They are primarily found in Japan and Tahiti, and their flat side makes them a great choice for statement pieces.
Baroque Pearls:
Baroque pearls are known for their non-spherical, irregular shapes, which give them a unique, artistic look. These pearls offer a bold and creative appearance, making them perfect for modern or eclectic jewelry designs. Baroque pearls have medium to thick nacre and come in a range of sizes. These pearls are cultured in both saltwater and freshwater environments, with their irregular shapes a result of the bead or tissue used in the culturing process.
Seed Pearls:
Seed pearls are the smallest type of pearl, typically under 2mm in size. These tiny pearls are often used in vintage-style jewelry, where they are woven together to create intricate, detailed designs. Despite their small size, seed pearls have a smooth surface and are known for their delicate appearance. They are often seen in antique or highly detailed jewelry pieces and are cultivated naturally, though some may also be cultured.
Natural vs Cultured Pearls
Natural and cultured pearls are both beautiful gems, but they are formed in different ways. Let me explain what makes them unique and how they differ.
What Are Natural Pearls?
Natural pearls form naturally without human intervention. When an irritant like a grain of sand or a parasite enters a mollusk, the mollusk reacts by secreting layers of nacre (a substance made of calcium carbonate and proteins) around the irritant. Over time, these layers build up, and a pearl is formed.
- Rare: Natural pearls are extremely rare, and finding one can be very difficult. This is why they are often irregular in shape and size.
- Price: Due to their rarity, natural pearls are typically much more expensive. Each pearl is unique, making them highly valuable to collectors.
What Are Cultured Pearls?
Cultured pearls are made with human help. In a controlled environment, a bead (typically made of mother-of-pearl) or a piece of tissue is carefully inserted into the mollusk. The mollusk then begins to coat the bead with nacre, forming a pearl. This process happens in pearl farms, where conditions are controlled to encourage consistent pearl growth.
- Consistent: Since the environment is carefully managed, cultured pearls tend to be more uniform in shape, size, and luster compared to natural pearls.
- Price: Cultured pearls are more affordable than natural pearls because they are easier to produce in large quantities.
Key Differences Between Natural and Cultured Pearls
- Formation:
- Natural Pearls: Form naturally when an irritant enters the mollusk and is coated with layers of nacre.
- Cultured Pearls: Form when humans insert a bead or tissue into the mollusk to start the process of pearl creation.
- Rarity:
- Natural Pearls: Extremely rare because the conditions for their formation don’t happen often in nature.
- Cultured Pearls: More common because they are produced in controlled environments on farms.
- Price:
- Natural Pearls: Cost more because they are rare and difficult to find.
- Cultured Pearls: Are more affordable due to the controlled production process.
- Shape and Size:
- Natural Pearls: Typically irregular in shape and size because the process is natural and unpredictable.
- Cultured Pearls: More consistent in shape, size, and luster, as the process is carefully controlled in pearl farms.
How to Choose the Right Types of Pearls
Choosing the right types of pearls depends on your style, budget, and the occasion. Let’s break it down in simple terms to help you decide.
Consider Your Style:
If you’re looking for a classic, elegant look, Akoya Pearls are a great choice. They’re known for their perfect round shape and high luster. On the other hand, if you want something larger and more luxurious, South Sea Pearls are ideal. They have a bold presence and are perfect for making a statement.
Budget:
If you’re on a budget, Freshwater Pearls are affordable yet versatile. They come in a variety of shapes and sizes, making them a popular option for many. If you want something more unique, Keshi Pearls and Mabe Pearls offer an artistic touch with their distinct shapes and interesting features.
Occasion:
Think about where you’ll be wearing the pearls. For a bold, dramatic look, Tahitian Pearls are perfect—they’re dark and exotic, making them a great choice for statement jewelry. If you’re after something more delicate and vintage, Seed Pearls are small, elegant, and often used in antique designs.
Caring for Your Pearls
Proper care is essential to keep your pearls looking beautiful and shining. Here’s the technical breakdown of how to care for them:
Storage:
- Soft Pouch or Jewelry Box: Store pearls in a soft pouch or velvet-lined jewelry box to avoid scratches from other jewelry.
- Separate Storage: Keep pearls away from harder gemstones (like diamonds) that can scratch their surface.
- Cool, Dry Place: Store pearls in a cool, dry place away from direct sunlight and heat to prevent damage to the nacre.
Cleaning:
- Soft, Lint-Free Cloth: Use a soft cloth to wipe off oils, dirt, or makeup after wearing them.
- Avoid Harsh Chemicals: Do not use bleach, ammonia, or harsh soaps as they can damage the nacre and affect the luster.
- Water: Never immerse pearls fully in water. If necessary, clean with a damp cloth (with a tiny amount of water).
- Avoid Perfume & Hairspray: Don’t spray perfume or hairspray directly on pearls as the alcohol can dull their shine.
Wear:
- Avoid Rough Surfaces: Pearls are delicate—don’t wear them during activities where they could get scratched (e.g., sports or gardening).
- Protect from Chemicals: Avoid wearing pearls when applying lotions, perfumes, or hairspray, as these can affect their surface.
- No High Heat: Don’t expose pearls to high temperatures (e.g., saunas or hot tubs), as extreme heat can damage them.
By following these steps, your pearls will stay in great shape and maintain their beauty for years to come!
