Amazing...period.
JFC on a popsicle stick in low rise jeans.  i have never been more pleased with a piece of jewelry.  The ring is essentially the same weight as a silicone ring..practically weightless.  It looks like it does in the picture, it's extremely comfortable and because it's carbon fiber I trust it is durable.  I held it in front of a desk lamp for 30 seconds and then turned off the lights and it glowed!  I am sure after a day absorbing light this will be a really cool thing for hanging out at night or maybe on stage at the open mic!  It's a cool conversation starter.  Teal is my favorite color and this thing is just amazing.  I would have paid 200 dollars for this.
