Have it engraved.
The road you will need to take to get it done 'your way' will be an invaluable lesson.
You will put a lot of time in the research of an engraver that will meet your expectations.
You will then collaborate on what you want done, the engraver's opinions, their skill level, and, agreements to get this all accomplished.
Weighing in on top of all that is the cost to have it completed.
A lot of people throw their two cents in about 'recovering costs'.
That's not something to even consider on a project this personal.
Don't let that interrupt your thought process on having a 'one of a kind' piece of art fabricated just for you.
If your ultimate goal is to sell it, down the road, then have it engraved in the 'cookie cutter' fashion. Pick a 'look' from catalogs and books and follow what's already been done.
If you truly want something unique to you then have it engraved your way so that you may cherish it forever.
I sincerely hope you get it engraved. You will have something to be proud of.
