Mood rings have actually stood the taste of the time in predicting one’s mood. The mood rings were specially designed not only for an accessory purpose but also to reveal the wearer’s true emotions.

This is made possible with the use of stones which are made up of thermotropic liquid crystals. That moves and bends when there is a temperature change.

As the crystals move, there is a change in the color they express. The rings exhibit different colors, which is a representation of different emotions or feelings.

The mood rings have come a long way. They were very popular in the 1970s and they are still very popular even now. Mr. Joshua Reynolds is credited for being the inventor of the mood ring.

The stone present in the ring changes its color regarding the mood and emotional state of the person wearing it.

Modern mood jewelry is designed from a flat strip containing liquid crystals that have a protective coating. Through twisting, the crystals will respond to changes in temperature.

Twisting changes molecular structure, which in turn modifies the wavelengths of the light reflected or absorbed.

Crystals are well calibrated to provide a pleasing blue or green color when a person’s temperature is at 82 F (28C) at average resting peripheral.

As this peripheral body temperature increases, it does so in relation to happiness and passion the crystals will twist to reflect blue. When a yellow color is reflected, this means that you are excited or stressed.

This happens when the flow of the blood is directed away from the skin and in turn directed more to the internal organs thus causing a cooling effect on the fingers, which in turn makes the crystals twist in other directions.

The ring will appear black and unresponsive or dark gray if the weather is cold or the ring is damaged.
