Japanese firm makes world's smallest diamond ring
Kyodo / July 17 TOKYO, Japan - Hitachi High-Technologies Corp. has produced a micro diamond ring , which can only be seen under microscope and is believed to be the world's smallest, by utilizing technology normally used to produce semiconductors. The ring, with a 0.02 millimeter diameter, bears a five billionth of a carat diamond.

Why?

Why?

The point is to show they can make really, really tiny stuff. Things like this are the precursors to functioning nanotechnology, and making something like "the world's smallest diamond ring" will get them more attention (and funding) than saying, "we can make tiny round objects with holes in the middle."

Hey, I completely understand the need to demonstrate the technology, but a diamond ring? Now, a baseball cap - that would be something...
