The traveler's guide to gem, mineral, antique, and collector shows worth the trip.

The Expo Almanac covers the world's most compelling specialty shows, collector fairs, and trade expos that double as must-visit travel events. We evaluate each show on scale, rarity of vendors and specimens, public accessibility, surrounding destination experience, and calendar timing. Our editorial team researches both the event itself and the broader trip it anchors — so readers arrive informed and ready.
