As jewelry, chicken-blood stones earn the "Display Only" grade for wearability. Reserve this material for display or decorative purposes only. Furthermore, store or display any chicken-blood stones away from sunlight, since cinnabar tends to turn brown when exposed to sunlight. Any change in an object's prized red color will lower its value and appeal.

Although the quartz content has a high hardness of 7, clay and cinnabar have very low hardness (2-2.5). This variation makes working with this material quite challenging for lapidary artists.
