My FIL gave me this old mood ring he found - it is from the 50's. Just for fun, I put it on and it turned brown. Then my dh and kids all tried it, and it turned bright blue for them. So dh & I went shopping yesterday (in a terrible blizzard, may I add!!) for our children's Christmas gifts. I kept the ring on, and kept glancing at it because it was so gaudy and I could feel it. Anyway, I had such fun shopping for the kids. The ring was ocean blue, then greenish aqua while we were shopping. I just kept throwing more and more toys into the carts we had. The ring stayed that beautiful color the whole time. UNTIL......the cashier FINALLY finished ringing everything up and told me the TOTAL!! I almost passed out! We get to the car (in the blizzard) and I look at the ring, and it was brownish black! Anyone know what that means? Do these things really work, and if so did the color go from glorious, beautiful blue because I was having so much fun....to icky brown because I was sick over what we spent? Just wondering, cause the thing came with no manual.
