Easter might be over, but fancy, colored eggs aren’t only for this holiday! Back in 2015, we featured Koen Zwanenburg’s original wedding-themed LEGO Fabergé Egg, but now he’s back with more. Named for the most famous creator of exquisitely handcrafted ceramic, gold, and jewel-encrusted eggs, these rare and precious gifts were made for Russian royalty. Each one has a hidden surprise inside, and today they’re worth millions of dollars. Inspired by the design, Koen has graced us with several of his own.

Just like the real deal, they open to reveal a surprise. (All except for the one made with gold radar dishes because the unique design doesn’t allow for it to open.) One egg even opens vertically instead of horizontally! Also like the real thing, these each have a different theme and name. The one below, for example, is called The Sea Egg.

Koen (Swan Dutchman) isn’t the only one who makes LEGO Fabergé eggs. We featured a similar one by Marion Weintraut. But if you’d like to see more of Koen’s fabulous work, check out his opulent, lifesize King Tut mask or his collection of adorable animals that you can build too!
