Thanks for the infos (and the quick reply). The engraving was meant to be for a relationship ring, so certainly more than for coolness. But I fear the increased cracking/parting chance you've mentioned, so I'll probably just order one without it.

I've seen on the roadmap that there should be engraved rings somewhere and
I also found on the Kickstarter Updates page, that engraved rings have been shipped.

I haven't found the option in the store though. Am I missing something?
