Glory
You could be the proud winner of the Antonio C. Bonanno Award for Excellence in Gemology and receive a little medal. Nope, it isn't diamond-encrusted. That little medal is it. Look happy.
You could also win a GIA jewelry design award or a GEMMY. Again, these won't get you any free gems—but the recognition from your peers will feel pretty good.
If feeling good is what you're interested in, take a moment to consider how many people will be made happier because of your work. Jewelry carries a lot of meaning. Think of all the happy couples who'll get engaged or married with your jewelry. Think of the grandma whose wedding band you resized so she can still wear it without it hurting. Think of the families whose heirlooms you'll repair and shine up.
Who needs a pile of diamonds, anyways?
