First of all, we must understand that agarwood is not so famous until now. In ancient times, agarwood was loved by emperors' concubines and nobles, because agarwood not only can be used as medicine, but also can be worn or collected at home, with many functions. Secondly, the existence of agarwood is not only unique, but also its workmanship and texture are the reasons why people are crazy about it. Unlike ordinary gold jewelry, it has no uniqueness and can be made into exactly the same thing. No matter what it is used for, it can play a different role. Moreover, although agarwood is a good thing, as long as it is agarwood, it does not mean that it has collection value. This point must be paid special attention to by fragrant friends, especially novices, because agarwood has two levels. The first one belongs to ornamental type, and the second one belongs to collection type. Ornamental agarwood generally has no collection value and is generally used for daily wear and play. Artificial agarwood belongs to the play type, and wild agarwood belongs to the collection type. The more exquisite and valuable, the more collectible.
