The LEGO Ideas Mineral Collection (Set #21362) is a premium 880-piece building set designed for adults ages 18 and up. This collectible display features brick-built models of six stunning minerals: golden pyrite (fool's gold), purple amethyst geode, blue fluorite, watermelon tourmaline, reddish-pink rhodochrosite, and tangerine quartz. Each mineral showcases clever building techniques using transparent LEGO bricks to capture the shimmering beauty of real crystal specimens.

The set includes three freestanding modular shelving units that can be arranged together or displayed separately. When combined, the display measures over 7 inches (18 cm) high, 11 inches (28 cm) wide, and 3 inches (7 cm) deep. The construction utilizes advanced SNOT (Studs Not On Top) building methods, clip and bar combinations, and hinge brick assemblies to create dynamic crystal angles and realistic mineral textures.

This set introduces an innovative new LEGO element: the "Brick Special 1x1x1 2/3 with 2 Studs on 3 Sides" in bright green and dark pink. The instructions are divided into three booklets, enabling collaborative building experiences. A unique gift idea for rock collectors, geology enthusiasts, and science and nature lovers.
