Spotted something interesting in the clearance aisle: the Lego Ideas Minerals Collection is showing up marked down at Costco. This 880-piece set designed for adults might be exactly what you need to scratch that building itch.
This isn’t your typical Lego castle or spaceship—it’s a geological showcase featuring ten different buildable mineral specimens with their own display stands. The set includes favorites like rose quartz, amethyst, pyrite, and celestite, each designed to capture the natural crystalline structures in brick form. It’s part of Lego’s Ideas line, which means it originated from a fan submission that got enough votes to become a real product.
Lego’s adult-focused sets have been holding their value pretty well, and this particular collection appeals to both builders and anyone who appreciates natural history displays. Clearance pricing varies by warehouse, so your mileage may vary on whether this feels like a must-grab.
This is likely hitting clearance because it’s been on shelves for a while and Costco needs to make room for newer inventory. The Lego Ideas line tends to have shorter production runs than mainline themes, so once it’s gone from stores, you’re usually looking at secondary market prices. If you’ve been eyeing this set or know someone who loves geology, crystals, or just unique display pieces, now’s probably the time to act before inventory dries up.
This is definitely one of the more unique Lego sets to hit clearance—perfect for the rock collector (pun intended) in your life. Have you seen this one at your local warehouse, or are you more into traditional Lego builds?
