I love rings. All kinds of rings. You've got to check out the Carrotbox if you love 'em too. This site has been around for years and I've been a fan since coming across it years back. This site is dedicated to rings made of materials other than metal (the author is allergic). She also writes an awesome ring blog with super links to many talented jewelers (me included!). The rings on the blog do include metal ones. Go check it out if you have a minute...although with the amount of cool pieces you could be here a very long time.
