When celebrities dress for a premiere or high-profile party they nearly always cover themselves with diamonds, platinum, gold and other fine jewelry. The jewelry's nearly always borrowed -- and pricey -- but it's fun to look at.

When those same celebs are off to more personal events, they're more likely to wear their own jewelry. That's when we get a glimpse of their true likes and dislikes. But mix the two types of events and you'll find that celebrities do help set jewelry trends.
