In the amazing step-by-step gallery below, Redditor laporkenstein shows how he forged a custom wedding band for himself out of a Gibeon meteorite.

There are captions in the gallery that help explain a bit of the process. I’ve also compiled a few additional details below that were culled from the comments section of this epic endeavour. How cool is it that not only did he forge the ring himself, but it’s made from a meteorite that was previously floating in space!
 
Project summary:

- The ring is made from a Gibeon meteorite which is technically iron with 10-12% trace elements. It was about $200 from a website called “rocks on fire”
- Verified the ‘authenticity’ by etching the meteorite with PCB etching fluid to reveal Widmanstaten patterning. It’s a crystalline formation that can only be formed through millions of years of slow cooling in zero gravity
- Ring has double helix twist using Japanese mokume techniques
- The gap was filled with silver solder and blackener was used to match the silver to steel gray
- The ring took about four days to create
- Works professionally as a custom fabricator for the film industry. Make things for movies like: stunt safe weapons, hand props, and small scale special effects
- Make sure you get a Gibeon meteorite as they have a higher carbon content and wont rust when worn as jewellery
