Review on Color Changing Rings: Cool Titanium Steel Couple Ring Gift with Temperature Change Heartbeat ECG Design - Black/Gold/Rose Gold/Silver, Size 6-12 by Elvis Bragg

I love this ring but it really should come with a color chart (the only reason I'm deducting 1 star) so you know what the colors mean. You can get them online, but the manufacturer can also provide a little guide. However, like every other color ring I've bought, the colors don't change much (since my emotions don't change much I guess). Mine stays either black or dark blue. I'd love to see other colors and what they look like, but no luck. Otherwise it's a good ring, I really like the pattern (heart plus heartbeat) and the size. UPDATE: I foolishly put this ring on, when I washed my hands! Whine! Currently the ring looks cloudy when I'm not wearing it. After holding it on my ring for a while it will (thankfully) turn back to a nice vibrant color, but just a word of warning: DON'T FORGET TO TAKE IT OFF WHEN SHE SHOWER, MY HANDS!
