Grade-Mixing of Oud: How Do You Detect the Misleading Blend?

We now move from physical intervention to deception in the description. Its first form is grade-mixing: selling a blend of pieces of varying quality under the name and price of the highest grade. This fraud leaves no physical trace in the single piece, but it deceives you in the "average" of what you buy. In this article we show how it happens and how you guard against it.

Where does this article sit? This is from the "types of adulteration" in the guide to detecting adulterated oud, and it comes after adding weight with external materials.

What is grade-mixing?

It is that a quantity of oud is sold to you (especially small pieces or chips) described as a high grade, while it is in fact a blend: some of the stated grade, and most of lower grades. So you pay the price of the highest and obtain a lower average. This is common in selling by weight where it is hard to inspect each piece on its own.

Remember that the grades themselves are not globally standardized (as we showed in the grades guide), which leaves room for manipulation: it is easy to mix disparate pieces under one name because no strict criterion separates them.

How do you guard against mixing?

Because it is a deception in the description, not a physical intervention, your weapon is not the home test alone but transparency and inspection by sample:

  • Inspect a random sample: when buying a quantity, inspect pieces from different places, not from the top only, for the good ones may be placed on the surface.
  • Compare consistency: a single honest grade is relatively homogeneous in color, weight, and scent; a large variance within "one grade" is suspicious.
  • Ask for documentation: a seller who sorts their grades clearly and states what you are buying is more trustworthy than one who sells a vague "blend."
  • Beware chips and small pieces: they are the easiest to mix because inspecting each grain is impractical; buy them only from a documented source.

The rule: the greater the variance within what is sold as "one grade," the higher the likelihood of mixing. And the transparent sorting from the seller is the best guarantee.

Did you know? Inspect from different places, not the top only

The good pieces may be placed at the top of the quantity to deceive a quick inspection. Inspect samples from the middle and the bottom too, so you know the "average" of what you are buying, not its facade.

What do you do if you are in doubt?

If you notice a large variance within what was described as one grade, ask the seller about their sorting criterion, and request to inspect samples from different places. And do not pay the price of the highest grade for a blend whose average is lower. And it is better to buy from someone who sorts their grades transparently and states what is in each type. And in the following article we move to another form of deception: changing the country of origin.

Did you know? The absence of a standard criterion makes mixing easy

Because oud grades are not globally standardized, it is easy to mix disparate pieces under one name. So rely on the sorting of a documented seller and their consistent ladder, not on the grade name alone.

Transparent sorting, not a vague blend

We sort our grades clearly and state what you are buying, and provide the sample so you verify. Begin with a sample by which you assess the consistency of the grade yourself.
