Wouldn’t it be great to be able to tell your Dominant’s or submissive’s mood without having to ask? They’re baaaack!
The mood ring is thought to be invented by Joshua Reynolds, a New York City marketing executive who is said to have first popularized the rings in 1975. He saw a friend use a thermotropic tape on a child’s forehead to take their temperature (Do you remember those?) and thought the liquid crystals could be used elsewhere. Reynolds marketed the rings as “portable biofeedback aids,” and he was able to convince the era’s most popular department store, Bonwit Teller, to carry them as accessories.
In the 1970’s dievca had one of the cheap metal versions – did you? Bonwit’s offered a silver version for $45 and the gold went for $250. The ‘stone’ of a mood ring was a hollow quartz or glass shell containing thermotropic liquid crystals. Modern mood jewelry is usually made from a flat strip of liquid crystals with a protective coating.
Believing in a mood ring is like believing in astrology. Mood rings can’t tell your emotional state with any degree of accuracy, but the crystals are calibrated to have a pleasing blue or green color at the average person’s normal resting peripheral temperature of 82 F (28 C). The crystals respond to changes in temperature by twisting. The twisting changes their molecular structure, which alters the wavelengths of light which are absorbed or reflected. ‘Wavelengths of light’ is another way of saying ‘color’, so when the temperature of the liquid crystals changes, so does their color.
As peripheral body temperature increases, which it does in response to passion and happiness, the crystals twist to reflect blue. When you are excited or stressed out, blood flow is directed away from the skin and more toward the internal organs, cooling the fingers, causing the crystals to twist the other direction, to reflect more yellow. In cold weather, or if the ring was damaged, the stone would be dark gray or black and unresponsive.
The jewelry firm Leo Black in NYC has brought back the mood rings in 14K Gold or Rose Gold which means they won’t discolor like dievca’s 1970’s ring. Ah, well — her crystal busted, too, so her ring stayed black…
The Leo Black versions may look like dievca’s ring, they are more expensive than the Bonwit Teller versions, but what do you expect in 40 years?
