Does a mood necklace work differently from a mood ring?


I see that your site deals more with mood rings than mood necklaces.  Are they the same?  Are the colors the same?  I would think that a mood necklace would work just as well as a mood ring since the both sit next to the skin and change colors with changing temperature.  What do you think?


Some mood ring devotees would say that a mood necklace works the same as a mood ring.

But, there is a big difference that I will explain.

True, they both sit next to the skin.  It’s also true that both mood necklaces and mood rings “measure” temperature by changing color via a thermochromic reaction in the liquid crystal inside the “stone” of the ring (the “stone” is usually a hollow glass shell filled with thermochromic liquid crystals).

But, here is the difference…

For a mood ring to work properly, it has to serve as a “biofeedback” device of sorts.  Hand and foot temperature can be used to measure stress, moods, and even to diagnose certain diseases (according to many therapists).

In fact, you can purchase a small, inexpensive Biofeedback Machine from

Guess how this amazing device works?  It measures the temperature of your finger… JUST LIKE A MOOD RING!  But, here’s the key… you have to wear it on your finger.  It’s the most accurate measurement of stress, mood, disease, etc.

I hate to be the one to tell you this, but mood rings work better.  Mood necklaces look very nice, but they simply do not work as well as mood rings.  Here’s the reason:  Temperature of the torso stays more temperate and doesn’t fluctuate nearly as much.  Temperature of the hands and feet are a much better indicator of mood.

If you are interested in exploring the amazing world of biofeedback and all that it has to offer, I would suggest reading Biofeedback For The Brain: How Neurotherapy Effectively Treats Depression, ADHD, Autism, and More.  I read it for a cognitive psychology class not long ago, and it is quite good.  It presents empirical evidence that hand and finger temperature (as well as a variety of other methods) can be used to diagnose (and even heal) certain emotional, physical and mental maladies.
