I got my Mira early on like you. I've never been able to find the laser inscription on it, no matter how many times I've spun my ring or deepened the wrinkles between my eyes. I didn't ask my jeweler about it because I trust him and honestly I never thought about it when I dropped off and picked up my ring.
But I am curious to hear how you found yours -- if you do, that is. Is it so small that you need a stronger loupe than the standard 10x that I have?
And now here's a really dumb question... You and I were both very early adopters of Mira. You bought something like #3 and I bought something like #8. Are the numbers on our stones literally 3 and 8, and are therefore a single digit hiding behind a prong? I guess I assumed it said something like "MIRA 1234567" with whatever combo of numbers, but I have no earthly reason for why I assumed that.
Maybe Less will weigh in on this and set us straight.
Sharp mind, soft belly.
