Choosing an agarwood bracelet comes down to four numbers and one question: (1) your wrist circumference, (2) bead diameter, (3) bead count, (4) gram weight — and then, honestly, how much resin is in the wood. Everything else — poetic grade names, certificate logos, "century-old wild" claims — is decoration. If a seller can't give you those four numbers, you are not buying a bracelet; you are buying a story. This agarwood bracelet buying guide walks through each decision with the arithmetic written out, so you can check a listing before you pay for it.

Key takeaways
- Strand fit is arithmetic: inner circumference ≈ bead diameter × (bead count − 3.14). A 15 mm × 15-bead strand fits roughly a 17.8 cm wrist.
- Gram weight tells you more about resin content than any grade label. For a 15 mm × 15 strand: under 18 g is light resin, 24–27 g is high resin, 28 g+ is genuinely sinking.
- "AAA grade" is not a standard. Ask for origin, resin behaviour in water (float / half-sink / sink) and weight in grams.
- Budget bands, for reference only: entry plantation strands run roughly USD 80–300; wild Hainan or Vietnamese sinking strands start around USD 8,000.
- Agarwood is CITES Appendix II listed. Cross-border shipping requires permits — a seller who waves this off is the first red flag.
Most people shop backwards. They see a beautiful 18 mm strand, click buy, and discover it hangs loose enough to slide over the hand. Measure first.
Wrap a soft tape around the wrist bone, snug but not tight. Write that number down. Then add 1.0–1.5 cm for comfort, or 0.5–1.0 cm if you prefer a close fit. The result is the inner circumference you want the strand to have.
There's a useful bit of geometry here. If beads of diameter d touch along a circle, then:
Inner circumference ≈ d × (n − 3.14), where n is bead count and d is bead diameter in mm. Divide by 10 for centimetres.
That formula explains why nearly every strand on the market lands in the same narrow band — makers build to a standard wrist, not to yours.
| Bead diameter | Typical bead count | Inner circumference | Fits wrist |
|---|---|---|---|
| 8 mm | 21–23 | ~16.6–18.4 cm | Slim wrists, layering, women's wear |
| 10 mm | 19 | ~15.9 cm | Small wrists, everyday subtle |
| 12 mm | 17 | ~16.6 cm | Most women; slim men |
| 14 mm | 15 | ~16.6 cm | Average women's / slim men's |
| 15 mm | 15 | ~17.8 cm | Average men's — the workhorse size |
| 16 mm | 14 | ~17.4 cm | Average men's |
| 18 mm | 13 | ~17.7 cm | Larger men's, statement piece |
| 20 mm | 12 | ~17.7 cm | Rare, expensive, showpiece |
(Figures follow the formula above; real strands vary with bead roundness and knot spacing. Treat them as a starting point, then confirm with the seller.)
Two practical notes. First, bigger beads cost disproportionately more, because a large sphere of high-resin wood is far rarer than a small one. Moving from 12 mm to 18 mm at the same resin level can triple the price. Second, odd bead counts are normal — 14 or 15 is typical for men's strands, and some makers use 108-bead malas that wrap three times. Always ask for the count, not just the diameter.
At our Songzhuang workshop we routinely resize strands by ±1–2 beads for customers. It's a ten-minute job with elastic cord, but it only works if there's spare length — another reason to buy from someone who will adjust rather than someone who ships and disappears.
Here's the uncomfortable truth: there is no globally accepted agarwood grading standard. "A / AA / AAA" or "Grade 1–5" is a system each shop invents for itself. One seller's AAA is another seller's midpoint.
Use these four measurable proxies instead:
For reference, here is what different resin levels weigh in the most common configuration, a 15 mm × 15-bead strand (total bead volume ≈ 26.5 cm³):
| Resin level | Approx. density | Expected weight |
|---|---|---|
| Light resin, near-white wood | 0.5–0.65 g/cm³ | 13–17 g |
| Medium resin | 0.7–0.85 g/cm³ | 18–23 g |
| High resin, half-sinking | 0.9–1.0 g/cm³ | 24–27 g |
| Sinking grade | 1.0–1.2 g/cm³ | 28 g and up |
The same logic scales. A 14 mm × 15 strand (≈21.6 cm³) runs about 20% lighter; an 18 mm × 13 strand (≈39.7 cm³) about 50% heavier. If a listing claims "sinking" 15 mm beads but quotes 20 grams, the arithmetic doesn't work — that strand is mid-resin at best. Mandarin-reading customers often cross-check our numbers against two Chinese-language pieces: 沉香手串挑选思路 and 手串保养六条建议.
If you're new to beads generally, our Agarwood Beads 101 primer covers why cut, pore structure and strand symmetry matter as much as resin.
Scent is subjective, but origins cluster clearly enough to shop by:
Budget bands below are market ranges observed across retail channels in 2026. Market prices fluctuate; these figures are for reference only.
| Level | Typical 15 mm strand | Notes |
|---|---|---|
| Entry plantation, light resin | USD 80–300 | Wearable, faint scent, will not age into anything better |
| High-resin plantation / low wild | USD 400–1,200 | The sensible first real purchase |
| Wild Hui'an, half-sinking | USD 2,000–6,000 | Clear origin character, layered aroma |
| Wild Hainan / Vietnamese sinking | USD 8,000–25,000 | Collector territory |
| Qinan / kyara strands | USD 30,000 and up | Very few genuine examples exist |
Notice how wide the spread is. A "bracelet" can be a USD 100 souvenir or a USD 20,000 asset — which is exactly why the four numbers above matter. Two strands can look identical in photographs and differ by a factor of fifty.
One more thing: do the water test only if you're willing to accept the risk. Soaking raises the wood grain and can dull a bead's surface. Most experienced buyers judge by weight arithmetic and magnification instead, and only submerge a loose sample chip.
A case worth remembering. In March 2026 a Beijing architect came to our Songzhuang counter with a 15 mm strand he had bought online for about USD 390, listed as "sinking grade, wild Vietnamese". It was beautifully photographed. We put it on the scale: 21.4 grams. By the table above, that is a mid-resin strand — roughly 0.81 g/cm³, nowhere near sinking. Under magnification the oil lines were surface-level and the pores were filled. It was plantation wood, oil-enhanced. The strand itself wasn't worthless; priced honestly at USD 150–250 it would have been a decent everyday piece. What he'd lost was the difference between honest and claimed — about USD 150 — plus six weeks of arguing with a seller who had no shop to walk into. He learned to ask for gram weight first. We re-strung his beads and he wears them still.

Measure your wrist snugly and add 1.0–1.5 cm for a comfortable fit. If your wrist measures 17 cm, look for a strand with roughly 18–18.5 cm inner circumference. In practice most men do well with 15 mm × 15 beads (~17.8 cm inner) and most women with 12 mm × 17 or 14 mm × 15 (~16.6 cm inner). When in doubt, buy slightly loose and have a bead removed rather than stretch the cord.
Honestly priced entry-level plantation strands start around USD 80–300; high-resin plantation or low-grade wild pieces run USD 400–1,200; documented wild Hui'an half-sinking strands sit in the USD 2,000–6,000 band; and genuine wild sinking Hainan or Vietnamese strands typically begin near USD 8,000. Market prices fluctuate and these bands are for reference only. Anything advertised as "wild sinking" below USD 300 is almost certainly not either of those things.
Within the same bead size, yes — more weight means more resin, and resin is the source of both scent and value. But weight only means something relative to bead volume. An 18 mm strand at 30 g is lighter in resin terms than a 14 mm strand at 24 g. Always compare grams against bead diameter and count, never grams alone.
