Vintage 1970s mood ring, indicating its novelty design, which uses thermochromic liquid crystals to change color with body temperature, reflecting perceived moods like calm (blue), stressed (black), or excited (red/yellow).
"Mood Ring": The ring contains thermochromic liquid crystals that react to slight changes in your skin's temperature, which are associated with emotional shifts.
Marks: "PAT. 3802945" is stamped on the inside of the setting, as shown. It is a US patent issued to James on April 9, 1974.
***I did not test it mood changing color.
How it works (general color guide):
Black/Gray: Stressed, tense, or cold.
Blue/Green: Calm, relaxed, or at ease.
Yellow/Amber: Nervous, anxious, or mixed emotions.
Purple/Pink: Passionate, romantic, or excited.
