How to Tell Real Agarwood: Grain, Scent, Weight, Surface and the Seller, and What Each Check Can’t Prove

Real agarwood is the resin-filled wood that forms inside Aquilaria trees, and no single test proves a bead is real. Real agarwood varies widely: pale or almost black, faint or strongly scented, floating or sinking. So no one look, smell or number separates real agarwood from a good imitation. What you can do is gather evidence, then see whether the evidence agrees with itself and with the seller’s description.

Oudbracelet is the retail side of AgarwoodTown, which has traded agarwood since 2014. We weigh and film real agarwood from plantations every day. Copying colour, scent and weight all at once is hard, so a fake that passes one check often stumbles on another.

The guide works through five checks: grain, scent cold and warm, weight and density, surface finish, and the seller’s openness. Real agarwood owes the scent to a wide range of compounds formed in the resin, according to Naef in 2011.^{(Naef 2011)} First, the scent is warm and faint, never sharp or perfumed. Then the resin shows as uneven dark lines. Finally, check scent, grain and weight together, not any single test.

The chooser matches the check to the moment. First, pick where you are in the purchase. For example, a buyer browsing listings needs the buying guide, while a buyer holding a strand can run the density check at once. Second, pick what made you doubt the strand: colour too even, scent too loud, a weight that seems wrong, or a quote that looks too good. Each answer leads to the part of the guide, or the page, that tests the doubt. In practice, a single doubt is a reason to run all five checks, not to give up on the strand.

Agarwood is not a species of tree. Instead, real agarwood is the dark, resin-filled wood that forms inside Aquilaria trees after a wound or infection. The tree slowly deposits resin around the damage as a defence, over years, as a 2019 review by Tan and colleagues describes.^{(Tan 2019)} Plantation agarwood forms the same way, except that growers make the wound on purpose.

The scent comes from a large family of aromatic compounds in the resin, and chemists have catalogued a long list, according to Naef.^{(Naef 2011)} So real agarwood has three traits that matter to a buyer.

First, resin is uneven, so resin shows as streaks and patches through paler wood. Second, resin is heavy, so resin raises the density of the wood. Third, resin is aromatic in a way that responds to warmth. A fake has to copy all three traits of real agarwood at once, and copying all three is where a fake tends to slip.

Grain is the first check for real agarwood, because resin is visible: darker resin runs through lighter wood. The pattern should also differ from bead to bead. Round beads show resin as moving rings and flecks, while flat cube faces show long, clear lines.

Good signs: streaks of varying width, and beads that do not match each other perfectly. Warning signs: every bead the same flat, even brown, or colour that sits on top of the wood rather than in the wood. For example, a strand where every bead looks identical deserves a closer look under side light.

However, grain has limits. First, grain cannot tell you how much resin is inside a bead. Second, grain cannot show whether someone stained a pale strand of real agarwood to look richer. Resin forms unevenly after a wound, as a 2019 review by Tan and colleagues describes,^{(Tan 2019)} so irregular lines are exactly what genuine wood shows.

The aromatic compounds in real agarwood release more readily when the wood is warm.^{(Naef 2011)} So a genuine strand usually smells faint at room temperature, and noticeably fuller after a minute or two in a closed hand. That change is the thing to look for, more than the strength.

Wood soaked in fragrance oil tends to do the opposite. It gives a strong, sweet smell straight out of the packet, much the same warm or cold. Also, that smell may fade within weeks.

However, scent tells you little about quality. Real agarwood from plantations with modest resin can stay quiet even when warm. Scent also softens with age and storage, and a skilled blend of oils can fool a newcomer. So if you can, smell a strand of real agarwood you trust first. Our guide on whether agarwood beads smell goes further.

The comparison sums up the guide in five rows. Resin-bearing agarwood is irregular in colour, quiet in scent when cold, and fuller in scent when warm. Treated or imitation beads, by contrast, look too uniform, smell loud from the start, and hide the wood under a film. For example, a strand smelling strongly sweet straight from the packet and stays the same in a warm hand fails two rows at once. Additionally, time helps: added scent fades over months, while worn real agarwood darkens and softens slowly.

Density is weight divided by volume, and density is the third check because resin makes wood heavier. Most woods are lighter than water, according to Forest Products Laboratory data.^{(USDA 2010)} However, as resin fills real agarwood, the density climbs, and the most resinous pieces sink. The name chénxiāng, “sinking fragrance”, comes from the sinking pieces.

For round beads, the volume is plain geometry: a sphere with a 2 mm hole through the middle. For example, a strand of 17 beads of 12 mm holds about 14.74 cm³ of wood. The table below shows what different weights would mean for the same strand. Additionally, a scale that reads to 0.1 g is enough for the arithmetic.

The surface is the fourth check, and polished real agarwood should still look like wood under good light. You should see pores and the direction of the grain beneath the shine.

However, a few things are reasons to look harder. First, a thick, glassy film. Second, a tacky or oily feel. Third, colour collecting in the drill hole or in small cracks. Finally, a surface with no grain direction at all.

The cards below describe the treatments buyers most often ask about, in general terms. Methods vary, and we cannot say how common each treatment is. Some treated beads are outright fakes. Others are real agarwood with little resin, dressed up to look like more. For example, stained pale wood can pass at a glance but fails under raking light. Either way, look, scent and weight should agree.

Seller transparency is the fifth check, and the only check you can run on a listing photo. Before buying, look at how the seller behaves. A seller of real agarwood has no reason to hide the weight, the bead size or the bead count. A good seller should also happily show the actual strand rather than a catalogue picture.

Two things deserve caution. The first is “wild agarwood” at a low fixed price, in any size. Wild wood is scarce and regulated, since every Aquilaria species sits in CITES Appendix II,^(CITES) so the numbers do not add up. The second is a certificate with no named laboratory, or a promise about what a bead will do for you. Neither tells you anything about whether a strand is real agarwood. For example, ask for the exact weight, the bead count and a video of the actual strand, and judge the answers.

We sell real agarwood from plantations only, and our process follows the same checks. First you choose. Then we weigh and film the strand, with the weight on the display. Next, you approve or ask for another, and we send a PayPal invoice and ship.

Sales are final after you approve and we ship, so the video comes first. Still, transit damage, or a piece that differs from your video, is on us: we replace the piece (final sale policy). We also quote sinking-grade wood separately, on request.

Telling real agarwood from a fake is a matter of patience, not a trick. First, look at the grain in side light. Second, smell the beads cold and warm. Third, do the arithmetic on the weight and examine the surface. Finally, listen to how the seller answers your questions. When all five checks agree, you can be reasonably confident. When one check jars, however, ask again before you pay.

Also, be fair to pale, quiet strands. Plenty of honest, real agarwood is light, floats, and smells faint until warm. For example, a 17-bead strand of 12 mm beads that weighs 10 g sits in the light band of the table above, yet the wood can be entirely genuine. The goal is a strand that matches the seller’s description exactly.
