Crystals colors.

In 1975, New York inventors Maris Ambats and Josh Reynolds produced the first mood ring.

These rings, which change color depending on the temperature, reflect the change in body temperature associated with the wearer’s emotions. The colors produced by the thermochromic liquid crystal seduced immediately and became fashionable.

The composition of mood rings has changed since the 1970s, but they are still manufactured today.
Me and My Mood jewelry contains thermochromic liquid crystals.

When the temperature in contact with the jewel changes, the orientation of the crystals also changes, which changes their color, whether this change is due to the mood of the person wearing the jewel or due to the outside temperature.

While the old mood jewels had a uniform color, modern pigments do not necessarily follow this norm and can adopt surprising shades of color.

Amber – yellow tones: nervous.Green tones: calm.
Blue tones: relaxed, happy.
Purple – pink tones: passionate, excited, very happy.
Dark gray – black tones: tense, edgy.
Gray tones: worried.

Color of the hottest temperature are purple and pink, colors of the coldest temperature are black and gray.

And you, what color will your jewel take this morning?
