If you want to turn the gems into cash quickly, you'll probably have to spend some of your new-found wealth hiring wizards to teleport you from major city to major city. The idea here is to make sure you don't sell too many gems in one place, and therefore don't create too much of a pearl glut in the market anywhere. You'll also want to hold onto some of the gems in case you need cash quickly in the future. And if you picked up a large enough quantity of pearls, you may want to spread your sales of them over several years, again to avoid disrupting the economy too much.
Then drop a good chunk of your wealth on setting up a stronghold (making sure it's got income sources to be self-supporting) and staff. It may be possible (and legal) to buy your way into the nobility, which will be helpful if you want a castle but haven't done enough to have a title granted to you yet.
