I grew up in central Oregon, USA, the “thunderegg” capitol of the world. As a kid, an ultimate prize in treasure hunting was finding baseball-sized rocks that reveal beautiful crystals when broken in half. Unfortunately, giant Amethyst geodes aren’t found in Oregon. They’re not found in the Netherlands either, but that didn’t stop Koen Zwanenburg from building this exquisite replica from LEGO.

Standing almost two feet tall  and containing over 7300 perfectly placed pieces, this must have been a real feat! That’s especially considering trans-purple parts are hard to come by. The unique building technique combined with those lovely curves makes for a work of art!
