Hello again, I own both copper and silver jewelry. Will I harm
anything if I write on them with a Sharpe magic marker.

No. It may leave some small scratches after removal.

What do I do
to make the writing last forever.

"forever" is a big word. So this solution is not forever, but long
lasting. After writing on the gold or silver with a Sharpie, cover the
writing with clear nail polish.
