Agarwood is considered one of the most valuable natural treasures on Earth, holding deep cultural, spiritual, and Feng Shui significance. In many countries, its daily use is deeply rooted in cultural traditions, leading to a steadily increasing demand for agarwood incense and products.

But what exactly is agarwood? And why is the market flooded with fake or low-quality agarwood?

Agarwood is formed when the Aquilaria tree becomes wounded — due to external factors such as ants, storms, natural disasters, or human activities like carving or cutting. In response to these injuries, the tree produces a unique aromatic resin to heal itself. The wood that becomes infused with this resin is known as agarwood, and it is highly prized for its rich and complex fragrance.

Because of its high economic value, the agarwood industry is unfortunately targeted by counterfeit and low-quality products sold for profit. This often creates confusion among consumers and can damage the reputation of genuine agarwood trade. So how can you tell the difference between real and fake agarwood?

In this article, we’ll provide essential information to help you make informed decisions and choose agarwood that truly reflects its worth.

Based on its characteristics and origin, authentic agarwood is generally categorized into two main types: natural agarwood and cultivated agarwood.

Natural Agarwood – From Rare to High-Quality Sinking Oud

Natural agarwood (also known as oud) is the highest-grade and most valuable form of agarwood. It is formed naturally in the wild without artificial intervention, extracted from untouched forests. With a high resin (oil) content, natural agarwood is dense, aromatic, and often sinks in water — a key indicator of its rarity and quality.

Natural agarwood products, such as oud wood chips, oud powder, and bracelets, carry exceptional economic and cultural value. The higher the oil concentration and the heavier the piece, the more valuable it becomes. Premium types like Suyufi and Char are highly sought after in international markets for their purity and deep fragrance.

At Bình Nghĩa, we specialize in offering a wide selection of authentic, natural agarwood products. Our company has rare sinking agarwood pieces worth up to tens of thousands of USD, as usual its price depending on grade, origin, and depth of sink.

Cultivated Agarwood

Cultivated agarwood is produced by inoculating Aquilaria trees — the same species capable of producing natural agarwood. Typically, the agarwood is cultivated in trees that are at least 10 years old. After inoculation, it takes around 5 years for the tree to form the resinous agarwood. However, the success rate of resin formation depends on many factors, including the manufacturer's technique and experience.

Despite having a milder fragrance and slightly lower quality compared to natural agarwood, cultivated agarwood is still highly valued due to its scarcity and the time required to produce it. It serves as a more accessible yet premium option in the agarwood market.

How to Avoid Buying Fake Agarwood

Fake agarwood (or adulterated oud) refers to any product that is claimed to be agarwood but is actually made from imitation wood or mixed with low-quality or artificial materials.

To ensure that the agarwood you purchase is genuine, there are several ways to check — including scent, appearance, weight, and the way it burns. However, the most important indicator is the scent. Some pieces may appear very dark or black, but that doesn’t mean they are valuable — in fact, many of them are low-grade or entirely worthless.

Genuine, high-quality natural agarwood has a naturally dark color, but dishonest sellers often apply dyes or coatings to make fake pieces appear authentic. One reliable way to tell the difference is by looking for natural brown resin dots found in real agarwood. In contrast, fake or coated agarwood usually lacks these dots and looks uniformly dark.

How to Distinguish Real Agarwood from Fake Agarwood

The most important sign to distinguish genuine agarwood incense from fake is the pleasant scent that remains consistent throughout burning. Real agarwood does not produce a harsh burnt wood smell, unlike fake incense.
Also, fake incense can cause eye irritation or a burning sensation, so it's important to know the difference between natural, enhanced, and synthetic incense.

Water Test – A Simple & Popular Method

One of the simplest and most widely used methods to identify real agarwood is the water test. This is commonly used by experts and experienced collectors to determine whether the agarwood is the rare, high-value sinking type.

Principle of the Water Test

Natural agarwood forms over many years and accumulates high levels of resin inside the wood. This resin makes the wood denser and causes it to sink in water.
In contrast, fake or low-quality agarwood (or artificially injected types) are often lighter and float easily.

How to Perform the Test

1. Prepare a glass of clean water (filtered water is ideal).

2. Gently place the piece of agarwood into the water.

3. Observe the result:

Real agarwood with high oil content (sinking oud): Will sink immediately or within a few seconds.

Real but lower oil content: May float or hover, but the bottom end usually tilts downward.

Fake or unevenly oiled wood: Often floats on the surface, may show bubbles or oil streaks.

Things You Should Know About Real and Fake Agarwood

• Not all real agarwood sinks. If it’s underdeveloped or has low natural resin, it may still float. So, while sinking indicates rarity and value, it’s not the only proof of authenticity.

• Some artificially injected woods may also sink if soaked in large amounts of oil — so it's important to check the color, scent, and grain pattern together.

In summary, If the wood sinks completely, has visible resin lines, a rich natural scent, and no harsh odor — it is likely high-quality natural agarwood.

Why Identifying Genuine Agarwood Matters

Distinguishing between real and fake agarwood is essential for anyone who values and uses agarwood in their daily life. Understanding its origin, characteristics, and methods of identification will help you avoid poor-quality products and ensure both the spiritual and economic value of your purchase.

Whether through the water test, examining oil veins, or evaluating the fragrance, each detail plays a crucial role in verifying the quality of agarwood.
