Most mood rings change from black to yellow, green and then blue. A black mood ring may indicate the ring is cold or that the crystals have become unresponsive.

Question: How Long Do Mood Rings Last?
Mood rings change color in response to temperature, which is supposed to reflect your mood. Eventually a mood ring will turn black and stop responding. Here's a look at how long you can expect a mood ring to last and the factors that will affect its lifetime.
Answer: It's reasonable to expect your mood ring to last a couple of years. Some mood rings last around five years. Few mood rings from the 1970s have survived with functioning stones to the present day. Mood rings are notoriously susceptible to water damage. Most mood rings meet their end when water seeps into the stone of the ring and disrupts the liquid crystals, causing the 'jewel' to become unresponsive or turn black.

Mood rings may be damaged by exposure to high temperatures. Trying to resize a mood ring may damage it. Leaving the mood ring in a hot location, such as the dashboard of a car, also may irreparably damage the stone.

You can extend the life of your mood ring by removing it when your hands might get wet and by storing it at normal room temperature when you are not wearing it.
