GAUEIOUR Mood Rings, Adjustable Dinosaur Color Changing Ring, Cartoon Dinosaur Alloy Ring, Temperature Changing Emotional Opening Jewelry, Jewelry Gifts for Boys and Girls

Bought for my niece who turned 7 years old. She was extremely happy with the ring and the fit is perfect. Really good quality and the mood changing colour is great fun for kids 😊

Pretty ring.

My son loves it but one thing I've found is that it only changes between blue and purple. Even if put in different temperature water.
