I'll spill the beans on what I'm doing, I guess. I'm preparing to propose in a rather different way. My girlfriend and I never agree on design of anything (furniture, art, etc), so I'm proposing with all the raw components of a ring and I've lined up a jeweller to make the whole thing from scratch after we design it together.
Hoping to get a small film of the experience as well. I've already lined up the rock, already have gold and silver, but want to get all components of multiple gold colours so she can choose.
High purity is pretty important, obviously.
I'm actually an electrician and have access to a bunch of offcuts, obviously, but it would look like crap, proposing with busbar. Haha.
