How to Tell if Agarwood Is Real

Fake agarwood is everywhere. From dyed plantation wood sold as Kyara, to fragrance-oil-soaked beads that smell strong for two weeks and then go silent, the global agarwood market is a buyer's minefield. This guide gives you three reliable home tests — visual, water, and aroma — and flags the five most common scams. By the end, you will be able to look at a piece and have a defensible opinion about whether it is real.

Why This Matters

Agarwood is one of the most expensive natural products in the world, by weight, more valuable than gold in some grades. The combination of slow tree growth, low natural resin yield, and high cultural demand creates the perfect environment for fraud. A piece labeled "Sinking-grade Kyara" can sell for $500 per 100 g, while the same weight of fake or chemically induced wood might cost $20. The profit margin for the fraudster is enormous, and the detection difficulty for the buyer is high.

This guide is built on what we have learned grading Aquilaria sinensis at our workshop in Guanzhu Town, Maoming, China — the historical Capital of Chinese Agarwood. The three tests below will not catch every sophisticated fraud, but they will catch 90% of what is currently being sold online and in tourist markets.

Test 1: Visual Inspection

Hold the piece under natural daylight (not LED, not a warm lamp). Look at the surface and the cut faces. Three things to look for:

1.1 Irregular Resin Veins

Authentic agarwood shows irregular dark veins of resin running through lighter wood. The pattern is uneven, often branching, sometimes knot-like. This is the visual signature of natural resin deposition in response to fungal inoculation. Plantation wood, or wood treated with chemical resin, looks more uniform — the dark color is either absent or applied as an outer coating.

1.2 Grain Honesty

You should be able to see the wood grain underneath the resin veins. If the surface looks like a single uniform color (very dark all over, or glossy black), it is almost certainly stained. Authentic Kyara has visible structure: the resin veins are darker than the surrounding wood, but the wood itself is still visible and shows grain.

1.3 Cut and Polish Marks

FOREZA pieces are hand-cut and lightly hand-polished. You will see the soft scoring of a hand saw or knife, not the mirror finish of a CNC machine. A mirror-finished surface on "Kyara" is suspicious — it usually means the wood has been lacquered to hide defects or to give a uniform "premium" appearance.

Test 2: The Water-Sinking Test

This is the most reliable single test you can perform at home. It is also the test that catches the largest number of fraudulent "Sinking-grade" claims.

2.1 Setup

Use a clear glass filled with room-temperature water. Drop the dry piece into the water. Observe the behavior over 30 seconds.

2.2 Reading the Result

Test 3: The Cool-Burn Aroma Test

This test takes 10 minutes and a small agarwood heater (a $20 electric heater designed for incense is sufficient; direct flame will destroy the resin and should never be used).

3.1 Setup

Place the piece on an electric agarwood heater preheated to 80–120 °C. Do not use open flame, charcoal, or a cigarette lighter. The resin profile of authentic Kyara is destroyed above 200 °C, so you will get nothing useful from a flame test.

3.2 What to Smell

Authentic Kyara releases a multi-layered aroma in sequence:

1. First 30 seconds: a sweet, honey-like top note. Often compared to brown sugar or dates.
2. 1–3 minutes: a cooling, menthol-like middle note. Almost eucalyptus-like in clarity, but without the sharp bite of eucalyptus oil.
3. 3–10 minutes: a deep, woody base note. Sandalwood-adjacent, with a long, lingering finish.

3.3 What Fake Smells Like

Fragrance-oil-soaked wood and chemically induced resin release a single flat note that fades within minutes. There is no progression, no cooling middle note, and no deep wood base. The smell is often "perfumey" — closer to a department-store oud fragrance than to natural agarwood.

The 5 Most Common Agarwood Scams

Across the global online and tourist markets, these five frauds account for the majority of "fake Kyara" complaints. Knowing what to look for is the single best protection.

Scam 1 — Plantation Wood Sold as Wild Kyara

Wood from 5–10 year old plantation Aquilaria, force-inoculated with chemicals to induce fast resin formation. The result is wood that looks dark and resinous on the surface but has very little natural oleoresin. Test: the water test will catch it. Plantation-wood chips almost never sink.

Scam 2 — Fragrance-Soaked Beads

Lower-grade Aquilaria beads soaked in synthetic oud oil or perfume. The smell is strong at first but fades within weeks. Test: the aroma test will catch it. Genuine Kyara holds its scent for decades.

Scam 3 — Sugar-Water Pre-Soak to Force a "Sink"

Wood soaked in concentrated sugar water to artificially raise density. The piece passes the water test the first time, but the surface becomes sticky and crystals form as the wood dries. Test: smell and touch. Authentic Sinking-grade wood feels dry, smooth, and resinous; sugar-soaked wood feels tacky.

Scam 4 — Hainan or Vietnam Wood Sold as Guanzhu

Wood from Hainan, Vietnam, or Indonesia is sold as "Chinese Guanzhu" at a markup. The aroma profile is different (often sharper, less sweet). Test: ask for a certificate of authenticity that states a specific town, not a country or a vague region. See the FOREZA Certificate of Authenticity layout for what that should include.

Scam 5 — "Vintage 50-Year-Old" Stories

Sellers add a romantic backstory to justify a high price. The story is unverifiable and often fabricated. Test: the certificate should include a batch number, a date, and a grader's signature. If the certificate is missing those fields, walk away. See Why Your "Kynam" Might Just Be Chemically Induced for a deeper look at the industry side of this fraud.
