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. These crystals react to changes in temperature by twisting. The twisting changes their molecular structure, which alters the wavelengths of light or color that are reflected or absorbed. When the temperature of the liquid crystals changes so will their color and this is how mood rings work.
Can a mood ring tell your mood? While the color change can't indicate emotions with any real accuracy, it can reflect temperature changes caused by the body's physical reaction to emotions. When you're anxious, blood is directed toward the body's core, reducing the temperature at extremities like the fingers.
When you are calm, more blood flows through the fingers, making them warmer. When you're excited or have been exercising, increased circulation warms your fingers. While the temperature of your finger—thus the color of the mood ring —may change in response to your emotions, fingers change the temperature for any number of reasons.
So it's not uncommon for a mood ring to provide erroneous results based on factors such as the weather or your health. The stone of a mood ring consists of a thin, sealed capsule of crystals , which change color in response to shifts in temperature, covered by a glass or crystal gem.
These thermochromic crystals within the encapsulated layer twist in response to changes in temperature, reflecting a different wavelength color of light with each change. Old mood rings turned black or gray for another reason besides low temperature. If water gets under the crystal of the ring, it disrupts the liquid crystals. Getting the crystals wet permanently ruins their ability to change color. Modern mood rings don't necessarily turn black.
The bottom of newer stones may be colored so that when the ring loses its ability to change color it's still attractive. Since mood rings are sold as novelty items, a toy or jewelry company can put whatever it wants on the color chart that comes with the mood ring.
For anyone who came of age in the '70s or '90s, mood rings were more than a colorful accessory — they were supposed to reveal the wearer's true emotions with the help of a simple, color-coded key. And they were really, really popular. Most mood rings work in the same way: The stone itself is made up of thermotropic liquid crystals , which move and bend in response to changes in temperature.
When these crystals move, the color that they express changes. According to mood ring lore, each color represents a different emotion or feeling.
I certainly wore my share of mood rings as a kid, but never without a vague sense of distrust. I doubt anyone has ever had total faith in mood rings, but the very idea that their manufacturers would make such a lofty claim needled at me. Yes, I was kind of a weird kid. Plus, these things have been around for over 40 years.
If they have had such staying power, doesn't that mean that at least some people find them illuminating? On the other hand, during times when we are anxious or scared, chemicals in our body divert blood flow to our vital organs and muscles.
Since the blood is diverted to the internal organs, temperature tends to drop at our extremities. Changes in our mood cause many reactions in our body. Certain chemicals in our body are released into our blood, causing several responses. We tend to have less energy when we are sad. These changes are utilized by the mood ring. One major indicator during mood changes is the temperature. Normal body temperature is
