http://www.kinektdesign.com/product-gear-ring.phpevery nerd's dream come true! i think i pioneered wearing a ball bearing, which i think is still cooler. plus, the most exotic ones are like $30. of course you have to just happen to have a finger that fits one. they do not come in ring sizes.
i still think this is cool. i suppose they did not do a platinum one for a million dollars because it is too soft. i could see every hollywood star wearing one then lol.
sorry if this has been mentioned before. i searched but did not find.
