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 Tay Fair

I love this ring but it really should have a color chart (that's the only reason I'm deducting 1 star) so you know what the colors stand for. You can get them online, but the manufacturer can also provide a little guide. However, like every other color ring I've purchased, the colors don't change much (as I suspect my emotions don't change much). 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 while washing my hands! Whine! Now 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 light color, but just a warning: DON'T FORGET TO REMOVE IT WHEN SHOWERING MY HANDS!
