Agarwood Bead Shapes Explained: How 13 Cuts Show the Grain, Wear and Pack

Agarwood’s resin runs through the wood in lines and patches. The tree lays it down around old wounds.^{(Tan 2019)} In plantation wood, growers start that process on purpose. Even so, the resin still follows the tree’s own structure, not a pattern anyone chose.^{(Liu 2013)}

So the cutter cannot move those lines. Instead, the cutter decides which way you look at them. That one choice changes a strand more than almost anything else. In short, agarwood bead shapes are different windows onto the same grain.

For example, a round bead shows the grain as rings and flecks that change as it turns. A flat face shows a clean section, like a slice through the trunk. Meanwhile, a long barrel shows the longest unbroken run. The bead shape also changes how a strand feels, wears and packs. As a result, it changes the weight too.

We are Oudbracelet, the retail arm of AgarwoodTown, and agarwood has been our trade since 2014. Today we string thirteen agarwood bead shapes, from the classic round bead to rare carved cuts. Here they are side by side.

According to the USDA Wood Handbook, wood grain shows differently depending on how a piece is cut.^{(USDA 2010)} First, a round bead shows the grain as rings. Then a cube shows it as flat panels. Finally, a disc shows it along one edge, so the same wood can look like 3 different materials.

The chooser is a shortcut, not a rule. First, decide what you want to see: grain lines, a soft sheen, one band or an irregular outline. Second, decide how the strand will be used. For example, someone who counts prayers but loves grain might pick round beads for a mala and a barrel strand for daily wear. Part 7 asks the same questions in more detail, in four steps instead of two.

Grain is the direction of the wood fibres, and agarwood resin follows the tree’s own structure. Cut a log straight across and you see rings. Split a log lengthwise, however, and you see long lines. Every agarwood bead shape picks one of those two views, or a mix of both. The USDA Wood Handbook describes the same effect in sawn timber.^{(USDA 2010)}

Across the grain, the resin shows as spots, rings and small islands of dark wood. You see this view on the ends of a drum and the faces of a disc. Along the grain, by contrast, the resin shows as streaks. Streaks can run the whole length of a barrel or across two faces of a cube. A round bead shows both at once: lines at the “equator” blend into spots at the poles.

So figured wood, with bold streaks, rewards the long-line cuts. On the other hand, speckled resin often looks best as round beads. There, no single face has to carry the whole pattern. For example, pale wood with scattered dark flecks usually suits round beads better than cubes.

What is a round agarwood bead (yuán zhū)?

A round agarwood bead is a sphere drilled through the centre, and the round cut is the default for bracelets and malas. A sphere rolls easily between the fingers, so round beads became the traditional counting bead. For example, the beads on a 108-bead mala are usually round. A round bead also shows both grain views at once: lines at the equator and spots at the poles.

In Chinese bead culture, people read the full circle as yuánmǎn, or completeness. Round agarwood beads suit every size, from small mala beads to 20 mm statement strands. Additionally, neighbouring spheres touch at a single point, so the cord takes little strain. In total, we string 29 pure-agarwood round styles.

What is a cube agarwood bead (fāng zhū)?

A cube agarwood bead is a square-sided bead with softened edges. We saw the blanks square first and then soften the edges, so the beads sit comfortably. Flat faces show resin lines more clearly than any other agarwood bead shape. Each face is a clean window onto the grain, much like a plank sawn from a log. Traditionally, the square also stands for fāngzhèng: being upright and plain-dealing.

Cube strands pack tightly, so a cube bracelet reads as a band rather than a row of dots. In idealised geometry, a sharp-edged cube holds about 2.0 times the wood of a round bead of the same width. Real cubes have softened corners, so the true figure is lower. Together, cube and square make up 24 styles.

What is a disc agarwood bead (piàn zhū)?

A disc agarwood bead is a thin slice cut across the grain and stacked edge to edge with its neighbours. As a result, the strand looks like one continuous ring, with a line of pattern in every disc. Each disc is a small cross-section of the trunk, so the resin shows as rings and spots. Disc strands use many pieces and flex smoothly. For example, multi-wrap strands often use discs for exactly that reason.

However, discs carry the most end grain of any cut. According to the USDA Wood Handbook, end grain takes up and loses moisture faster than side grain.^{(USDA 2010)} So a disc strand needs the most care around water and heat. We offer 9 disc styles.

What is a drum agarwood bead (gǔ zhū)?

A drum agarwood bead is a short cylinder with rounded sides and flat ends. The name comes from a Chinese drum. Thanks to the flat ends, drum beads sit close without gaps. So a drum strand looks full and even. The sides show short lines along the grain, while the ends show rings.

Drums also size in fine steps, since one extra bead changes the fit only a little. Additionally, drums are forgiving of patchy resin, as the comparison below shows. In idealised geometry, a cylinder holds about 1.5 times the wood of a round bead per length of cord. For example, a drum strand and a round strand of the same width can differ clearly on the scale. We string 4 drum styles.

What is a barrel agarwood bead (tǒng zhū)?

A barrel agarwood bead is a short cylinder cut along the grain. The resin lines therefore run the length of each agarwood bead. Barrels suit people who like grain but want something softer than cube. Barrel beads also feel less formal than round beads. In the chooser above, barrel and drum are the picks for everyday wear.

For example, style R36 shows barrels as a middle ground between round and cube. Like drums, barrels hold about 1.5 times the wood of round beads per length of cord, in idealised terms. Finally, the flat ends meet face to face, so check the cord at the joints now and then. There are 3 barrel styles.

What is a long barrel agarwood bead (cháng tǒng zhū)?

A long barrel is a cylinder longer than it is wide, and this agarwood bead shape gives the longest unbroken run of grain. A long-barrel strand also has the fewest beads. No other bead shape shows off figured wood better. Still, a long agarwood bead has nowhere to hide a pale patch. For that reason, long barrels want even, figured wood along the whole length.

Additionally, sizing comes in coarse steps, since one bead changes the fit a lot. On the wrist, a long-barrel strand sits as a chain of flat-ish segments rather than a smooth curve. For example, style R44 holds the most grain per bead of the two styles pictured below. We offer 4 long-barrel styles.

Drum and long barrel are both cylinders drilled end to end, so the real difference is length. A short drum gives many beads and an even curve. A long barrel gives few beads and long panels of grain. In practice, patchy resin suits the drum, while evenly figured wood deserves the long barrel. Sizing follows the same logic: one drum bead changes the fit a little, and one long barrel changes the fit a lot.

Wood is not equally stable in every direction. Along the grain, wood barely moves. Across the grain, however, wood swells and shrinks as moisture comes and goes. According to the USDA Wood Handbook, end grain also takes up and loses moisture faster than side grain.^{(USDA 2010)} So agarwood bead shapes with a lot of end grain need the most care. First come discs, followed by the flat ends of drums. Keep both away from water and sudden heat.

Bead shape also decides where a strand rubs. Round agarwood beads touch neighbouring beads at a single point. As a result, round beads roll freely and the cord takes little strain. Flat-ended cuts, by contrast, meet face to face. Flat faces sit steady, yet the cord bends sharply at each joint whenever the strand flexes. The joint is usually where the cord thins first. Meanwhile, cube corners slowly round over with wear.

None of this makes any bead shape fragile. Our care guide covers the routine. Below, you can see what changes from cut to cut.

A strand of round beads is part wood and part air, because round agarwood beads leave gaps. Two spheres touch at one point, with gaps above and below. In contrast, flat-sided cuts such as cube, drum and disc sit flush and fill those gaps with wood. So at the same bead width, each agarwood bead shape puts a different amount of wood into a strand. We sell agarwood by weight, so the cut changes the quote as well.

The geometry is simple to work out. Take idealised 10 mm beads with a 2 mm hole. For the same length of cord, a sharp-edged cube holds about 2.0 times the wood of a round bead. A cylinder holds about 1.5 times; that covers drum, barrel, long barrel and a stack of discs. Real cubes have softened edges, and real strands curve. So the true gap is smaller, and you should read these figures as upper limits. For scale, a 10 mm round strand for a 16 cm wrist takes 20 beads with standard room.

Natural form is the cut that keeps the outline of the raw piece. Suí xíng means “following the form”. Here the carver removes as little wood as possible and keeps the outline the piece had. No two agarwood beads match, and no two strands match either. So the strand you receive will not look like the photo bead for bead. We shape heartwood pieces the same way. Between them, these two cuts make up 5 styles.

Four more agarwood bead shapes take extra work per bead: abacus, apple, bamboo-node and antique-cut. For that reason, we offer each in one design. Just ask if you want another size. For example, natural-form and heartwood strands suit a buyer who wants a piece nobody else has. Finally, raised points on irregular beads take wear first, so store these strands in their own pouch.

A still photo is a poor guide to bead shape, because photos flatten depth. For instance, a cube strand can look round from above. Likewise, a long barrel’s grain only shows when it catches the light. That is why we weigh and film your actual strand before you pay, whatever the cut. In practice, a short film shows depth, edges and light far better than a still image. Additionally, the film shows the scale reading, so the weight behind your quote is on record. Once you approve, we send a PayPal invoice and ship. Sales are final after approval; see the final sale policy. For wood, resin and stones, start with the buying guide.

Every agarwood bead shape is a different view of the same resin. An Aquilaria tree laid the resin down slowly, after injury, in lines nobody chose.^{(Tan 2019)} First, the round bead shows the grain softly. Second, the cube shows the grain frankly. Third, the disc shows a cross-section, and the long barrel shows the full length. Finally, the natural form shows the wood just as the piece came.

This guide mentions some cultural readings: completeness, uprightness, peace and steady progress. Each reading is a tradition of Chinese bead culture. We pass the readings on as context, not as a promise of any effect. So choose the cut you like on your own wrist, and see the strand on film before you pay.
