In the game of Splendor when you have a developer card with prestige points on it, is that the number of gems it produces also? Or is it just one gem per card?

Each card only gives a bonus of one gem. Prestige points are purely points.
For example, on page 3 of the rulebook, there is an example of a player gaining 4 prestige points and a single blue bonus from a development card.
Yes each card that you "purchased" gives you on extra "permanent" gem. And only one.
