How does a mood ring work?

Question

I bought one the other day and I was wondering how the colour changes? No guesses please! I want to know the real answer.

Answer 1

The "stone" in a mood ring is, essentially, thermotropic crystals covered or surrounded by glass. These crystals are very sensitive, and when the temperature changes, their components change, or "twist". Light that hits upon the crystals will have different wavelengths absorbed and reflected. The heat from the wearer's finger is conducted to the inside of the ring, and "twists" the crystals inside. The crystals then reflect different wavelengths of light, thereby changing the color of the ring.

The meanings of various colors:

Due to fluctuations in the making of mood rings by various companies, interpretation of mood ring colors are not universal. However, a certain standard is fairly prevalent, and is the only one commonly found in any form of documentation. This standard is based on the crystals being calibrated to have the color green reflected at 82 degrees Fahrenheit (27.7 degrees Celsius), which is the typical surface temperature of people. Variations of the actual "neutral temperature", caused by differing surface temperatures among different people, as well as effects from outside temperatures, cause mood ring measurements to differ, and make their readouts rather unreliable.

* Black: Tense, nervous, harassed, overworked; may also indicate a damaged ring
* Grey: Anxious, nervous, strained
* Amber: Nervous, emotions mixed, unsettled
* Green: Average reading. Active, not under great stress
* Blue-green: Emotionally charged, somewhat relaxed
* Blue: Relaxed, at ease, calm
* Dark blue/Purple: happy, romantic, passion[1]

When people undergo stress, their surface body temperature drops. This is represented in the mood ring's color phasing from the neutral green to amber, to grey, to black. Conversely, a passionate mood causes one's capillaries to move closer to the surface, raising surface temperature. This is rendered in the mood ring by the color moving toward blue-green, blue, and then a darkened blue.

Answer 2

Your perspiration and temperature changes depending on your mood. The mood ring feels the heat radiating off you, and your heat changes its color. For the most part, mood rings are accurate, but seasons have influences. During winter, mine almost always says I am calm or sleepy because my poor hands are never warm. But the rest of the time it's maybe only a hue or two off of my mood. I don't know what exactly the stone is, but I do know that some bored inventor/scientist people decided to study the heat of a person depending on their mood, and thus was born the mood ring. If you googled it, I'm sure you could get something, but this is pretty much the brief overview on how it works.

Answer 3

Temperature is what causes changes, put in somewhere cold, it turns black. This is an indicator of stress in a person, bloodflow is constricted to extremities. It has nothing to do with the sun.

Answer 4

it depends on ur body temp.
I don't know the exact colors, but I know for example; if you put a mood ring under warm/hot water, it will turn black.
experiment with it- play around

Answer 5

It basically is supposed to change colors when your temperature of your body changes.

Answer 6

your body heat....
when you get mad you feel hot(or when your embarrassed) your body heat changes the color of the ring, which means most of the time its true about your mood, it all depends on your mood which makes your body heat...
