Mood Rings contain thermotropic liquid crystals inside the stone or the band of the mood ring. These liquid crystals are able to show different colors at different temperatures. The liquid crystals in modern mood jewelry are usually made from a flat strip of liquid crystals with a protective coating.
Black serves as the mood ringâs default color, indicating a resting state. The darkest of shades may also represent stress, fear or angst. Consider the situation at hand as you interpret this color; a neutral black occurs during mellower moments, while stronger emotions typically pop up in intense colors.
