Geode Puzzle

These stunning, cutting-edge geode puzzles seduce the eyes while challenging the brain.


Hard Rock

Beautiful—and fiendishly difficult—these cutting-edge geode puzzles seduce the eyes while challenging the brain. And like real agates, each of which is unique, they all have completely different shapes, colors, and pieces.

Inspired by how a geode's crystalline structure is created in nature, these puzzles are created in a computer: a special simulation program develops an image by laying concentric layers of color radiating from the puzzle"s edge; an algorithm generates the puzzle piece patterns, twisting them into a maze of 180 distorted, intertwining shapes; and a computer-guided laser cutter shapes the pieces from birch plywood. You take them apart. We're confident you can put them back together. We apologize in advance for bending your mind. Made in Somerville, Massachusetts.

Agate patterns are all unique, so please note each puzzle will be, too. Color choices not available.

Due to the nature of this item, each is unique and will vary.

This was such fun to assemble! Finished it in a few hours. Would love to purchase again but not being able to chose specific color, afraid of receiving the same one.
