A good example of this embodiment may be seen in certain styles of Japanese pottery. In Japanese tea ceremony, cups used are often rustic and simple-looking, e.g. Hagi ware, with shapes that are not quite symmetrical, and colors or textures that appear to emphasize an unrefined or simple style. In reality, the cups can be quite expensive and in fact, it is up to the knowledge and observational ability of the participant to notice and discern the hidden signs of a truly excellent design or glaze (akin to the appearance of a diamond in the rough). This may be interpreted as a kind of wabi-sabi aesthetic, further confirmed by the way the glaze is known to change in color with time as tea is repeatedly poured into them (sabi) and the fact that the cups are deliberately chipped or nicked at the bottom (wabi), which serves as a kind of signature of the Hagi-yaki style.
