This question already has an answer here:

The Gemara sounds like they used the mysterious shamir worm to engrave the words on the Avnei Miluim on the Choshen. My impression is that they didn't have that in the times of the Second Temple, so how did they do it?

(The Rambam makes no mention of any Shamir in his Laws of Implements for the Temple and its Workers, if I'm not mistaken.)
