Yes, even this design can be a FREE download once I am fully funded for my RoboGuts™ S.T.E.A.M. Education Program Kits;

IF each viewer donates just $5 I'll be funded almost overnight and then all my designs become FREE downloads!  

The fastest and cheapest way to get all my .STL files FREE is to donate $5 to help fund school materials ... once I have $3,500 I'll convert all these files to FREE downloads.   https://www.gofundme.com/roboguts-kits-lessons

It's the ring ... 11.38mm diameter finger ... engagement or wedding I guess ... I try to avoid those kinds of things myself ... OTOH, it can be printed on a CupCake MakerBot or any other 3D printer ... probably a quality wax printer for a mold to make the real thing in gold. But if you do, I want to get paid for the design! This is another of many entries to the makezine.com/go/makerbot contest ... blog.makezine.com/archive/2010/04/makerbot_giveaway.html I really need a job ... but I can design a custom part if you like on contract.

If you successfully make this with a 3D printer please send me the build-file and machine type so it can be uploaded here for others to use.
