We've previously posted Paul Michael's delightfully geeky ring designs, including those inspired by Wonder Woman, Han Solo and the Death Star. He recently posted these two designs on his Facebook page.
I love the starship design! Michael has already made a wax mold and is working on a making this design a reality. The Starfleet logo is also nice, though one commenter notes that it could be difficult to make a Vulcan salute if the ring is worn on the middle two fingers.
