Biwa pearls stand out immediately from traditional round pearls. Known for elongated, irregular shapes and natural luster, these distinctive freshwater pearls can bring texture, movement, and an organic feel to jewelry designs.
But "Biwa pearl" doesn't always mean a pearl from Japan's Lake Biwa. Genuine Lake Biwa pearls are rare today, while many of the stick-shaped pearls sold under the Biwa name are actually Biwa-style freshwater pearls produced elsewhere.
In this guide, we'll look at the history of Biwa freshwater pearls, what makes authentic Lake Biwa pearls so rare, how to identify them, and what to consider when choosing Biwa-style pearl beads for your next jewelry project.
What Are Biwa Freshwater Pearls?
Biwa freshwater pearls are elongated freshwater pearls known for their irregular stick-like shapes, textured surfaces, and natural luster. The style takes its name from Japan's Lake Biwa, where freshwater pearl cultivation became famous for producing distinctive, non-round pearls.
Today, the term Biwa Pearl Beads is commonly used for elongated, irregular freshwater pearls drilled for jewelry making, including many Biwa-style pearls cultivated outside Japan. For an example of what this looks like, explore our Bronze Side-Drilled Biwa Freshwater Pearl Beads.
Stick Pearl Shape and Texture
Unlike traditional round pearls, Biwa pearls typically have long, narrow, flat, or baroque silhouettes. Their surfaces may feature subtle ridges, wrinkles, or other natural variations created during the pearl's formation inside a freshwater mussel.
Rather than looking perfectly matched, a strand of Biwa-style pearls often includes slight differences from bead to bead. These variations contribute to the organic texture and visual interest that make the shape so distinctive.

Natural Beauty Over Uniformity
Biwa freshwater pearls are a natural fit for designs where individuality matters more than perfect symmetry. Their elongated shapes can add texture and movement to necklaces, bracelets, and earrings, while their luster gives even highly irregular beads a polished finish.
Depending on their color and how they're paired with other materials, they can work well in minimalist, organic, coastal, or more eclectic jewelry designs. Browse our full selection of Freshwater Pearl Beads to compare Biwa-style pearls with other freshwater pearl shapes and finishes.
Where Do Biwa Pearl Beads Come From?
The Biwa name comes from Lake Biwa in Japan, where freshwater pearl cultivation helped establish the elongated, irregular pearl style associated with the name. While authentic Lake Biwa pearls are Japanese, many of the Biwa-style pearl beads available today are cultured in other freshwater pearl-producing regions, particularly China.
Lake Biwa and Japanese Pearl Culture
Located near Kyoto, Lake Biwa is Japan's largest freshwater lake and has an important place in the history of cultured freshwater pearls. Pearl cultivation in the lake became known for producing lustrous pearls with distinctive irregular shapes rather than the consistently round forms associated with many traditional pearl varieties.
These Japanese pearls helped establish the look that jewelry makers still associate with the Biwa name: elongated forms, organic surfaces, and considerable variation from one pearl to the next.

Modern Biwa-Style Pearls
Today, "Biwa" is often used to describe a pearl shape or style rather than a geographic origin. Many contemporary Biwa-style stick pearls are freshwater cultured pearls produced around China, where a freshwater pearl cultivation takes place on a much larger scale.
That distinction matters when shopping. A bead labeled "Biwa" should not automatically be assumed to come from Lake Biwa. If Japanese origin is important for your purchase, look for clear provenance or documentation specifically identifying the pearls as originating from Lake Biwa.
Why Are True Japanese Biwa Pearls So Rare?
Genuine Japanese Biwa pearls are rare today because pearl production in Lake Biwa declined dramatically during the second half of the 20th century. Environmental changes, including pollution and declining water quality, affected the freshwater mussels used for pearl cultivation and contributed to the collapse of much of the lake's historic pearl industry.
As production dwindled, authentic Lake Biwa pearls became increasingly difficult to source. Many of the genuine examples available today are older pearls or come from limited, documented Japanese production.
Limited Supply and Collectible Appeal
The combination of limited supply and historical significance has made genuine Lake Biwa pearls particularly interesting to collectors. Provenance also matters. Pearls that can be reliably traced to Lake Biwa may command considerably higher prices than contemporary freshwater stick pearls.
This is also why the label "Biwa" alone isn't proof of Japanese origin. Because the term is now widely used to describe elongated freshwater pearl shapes, buyers looking specifically for genuine Lake Biwa pearls should search for clear information about where the pearls were cultivated.
Availability of Contemporary Alternatives
Fortunately, you don't need a rare Japanese pearl to incorporate the distinctive Biwa look into a jewelry design. Contemporary Biwa-style freshwater pearls offer the elongated shapes, natural surface variation, and luminous finish that make this style so appealing, with far greater availability.
For most jewelry-making projects, focus on the pearls' luster, shape, surface quality, color, size, and drilling rather than geographic origin alone. These characteristics will have a greater impact on how the finished piece looks and wears.
At The Bead Traders, we offer a wide selection of Biwa-style pearls that can fit seamlessly into virtually every jewelry design. Learn more by reading our article, "How to Buy Wholesale Gemstone Beads Online with Confidence."
How Can You Identify Quality Biwa Stick Pearl Beads?
When evaluating Biwa stick pearl beads, look closely at their luster, surface, shape, size, and drilling. Irregularity is part of their appeal, so a quality strand doesn't need to be perfectly uniform. Instead, look for pearls with attractive natural variation, good surface donation, and clean drill holes suited to your jewelry design.
Luster and Surface Quality
Quality freshwater pearls should have an appealing luster that gives the surface a luminous, reflective appearance. Biwa pearls may naturally have ridges, wrinkles, and other textural variations, but these are different from significant chips, cracks, or damage.
Color can also affect their overall appearance. Depending on the strand, Biwa-style pearls are available in classic light neutrals as well as deeper peacock, copper, bronze, and golden tones.
Shape, Size, and Strand Consistency
Biwa pearls vary considerably in length, width, and overall shape. A strand with relatively consistent sticks can work well when you want repetition and symmetry, while more varied pearls lend themselves to organic or freeform designs.
Size also changes the visual impact. Larger sticks, such as our Vermeil Bezeled Biwa Pearl Pendants, can serve as statement beads, while smaller or narrower pearls are easier to incorporate as accents.
Drilling and Durability
Drill placement determines how a Biwa pearl will sit once it's strung. Straight-drilled pearls run along the length or central axis of the bead, while side-drilled pearls create a different orientation that can add movement and texture to a finished piece.
For example, our Peacock Biwa Pearls are straight-drilled, while our Garnet Red Side-Drilled Biwa Pearls offer a side-drilled option.
Whichever style you choose, look for clean drill holes without excessive chipping around the opening. Because elongated Biwa pearls can have narrow ends and irregular edges, handle them gently during stringing and finishing.
How Can You Use Biwa Pearl Beads in Jewelry Designs?
The elongated shape of Biwa pearl beads makes them especially versatile for designs that benefit from texture and movement. They can serve as focal beads, drops, strand accents, or contrasting elements alongside gemstones, chain, and metal components.
Minimalist Pearl Pendants
A single Biwa pearl can create a simple focal point without requiring an elaborate design. Add one to a fine chain using a wire-wrapped connection or compatible finding for a delicate pendant necklace.
Longer stick pearls are particularly well suited to this style because their irregular silhouettes add visual interest while keeping the overall design minimal.
Statement Earrings and Pearl Drops
Biwa pearls also work naturally as drops because their elongated shapes create movement below the ear. Use a closely matched pair for a balanced look, or choose two slightly different shapes to highlight the natural variation of freshwater pearls.
Pair them with metal beads and findings in sterling silver, gold-filled, or other finishes to complement the pearl color and overall style of the earrings. For similar inspiration, read our article, "Blue Freshwater Pearl Earrings: Styles to Make at Home."
Layered Necklaces and Mixed Strands
For necklaces and bracelets, Biwa pearls can be spaced throughout a strand, grouped together as a focal section, or mixed with other bead shapes to break up repetition.
Try pairing them with gemstone beads for contrast in color and texture, or alternate them with chain and metal components for a more structured design. Their irregular shapes also make them a natural choice for mixed strands where variation is part of the finished look.
How Should You Care for Biwa Pearl Jewelry?
Biwa freshwater pearls are relatively soft compared with many gemstones, so gentle handling can help preserve their luster and surface over time. Keep finished jewelry away from harsh chemicals, clean the pearls carefully after wear, and store them where they won't rub against harder beads or metal components.

Gentle Cleaning Habits
After wearing Biwa pearl jewelry, gently wipe the pearls with a soft, slightly damp cloth to remove oils and residue. Avoid harsh jewelry cleaners, detergents, and prolonged soaking.
You should also never clean pearls with ultrasonic or steam cleaners, as these methods can damage them. If a strand becomes damp during cleaning, allow it to dry completely before putting it away.
Safe Storage Practices
Store Biwa pearl jewelry separately from harder gemstones, sharp findings, and other pieces that could scratch the pearl surfaces. A soft pouch, fabric-lined jewelry box, or individual compartment can work well.
It's also best to put pearl jewelry on after applying perfume, hairspray, lotion, and other beauty products to minimize contact with chemicals. When handling or storing elongated Biwa pearls, take extra care around narrow tips and irregular edges, which may be more vulnerable to chipping if knocked or bent against harder materials.
Frequently Asked Questions
Are Biwa pearls real pearls?
Yes, Biwa and Biwa-style pearls are genuine freshwater cultured pearls when they are grown inside freshwater mollusks. However, the term "Biwa" doesn't necessarily mean a pearl originated in Japan's Lake Biwa. Many modern Biwa-style pearls are cultured elsewhere and named for their elongated, irregular shape.
Are Biwa pearls naturally shaped like sticks?
Yes, the elongated, flat, baroque, and stick-like forms associated with Biwa pearls develop during the freshwater pearl culturing process. They are not carved or cut into shape like gemstone beads, which is why individual pearls naturally vary in length, width, texture, and silhouette.
Do Biwa pearls come in different colors?
Biwa-style freshwater pearls are available in a wide range of colors, including white, cream, peach, pink, lavender, bronze, copper, and darker peacock tones. Depending on the pearl and supplier, colors may be natural or enhanced, so check individual product descriptions when color treatment is important to your project.
Can Biwa pearl beads be used for everyday jewelry?
Biwa pearls can be used for necklaces, earrings, bracelets, and other jewelry designed for regular wear. Because pearls are softer than many gemstones, however, they should be protected from scratches, harsh chemicals, and rough handling.
What stringing materials work well with Biwa pearl beads?
Biwa pearls can be incorporated into designs using silk or nylon thread, beading wire, jewelry wire, head pins, and chains. The best option depends on the size and placement of the drill holes as well as how you want the pearl to sit in the finished piece.
