Titan Ring Holder
This fully custom, solid titanium Titan puzzle was commissioned by an American customer to be part of his unique wedding proposal to his partner.
Once the puzzle is solved, it will open, presenting the successful solver with a mounted engagement ring as well as a commemorative coin which has special sentimental value to her.
The whole puzzle mechanism had to be redesigned, and it was a huge engineering struggle to get everything to fit inside how we wanted without the hugely valuable ring touching anything metal (it sits on and is held in place by the black acetal pieces), but we're thrilled with how the final product has come out.
As far as we know, she hasn't solved it yet...
