Why do some crystals grow as cubes and others as long points? This PDF is pure rock science.
This QuickStudy guide explains what makes a crystal system: the number of axes, their lengths and the angles where they meet. It covers all six systems, cubic to triclinic, with line drawings and example stones like diamond, topaz and malachite. It's a print-ready PDF of both sides. Nothing ships, and it's ready right after checkout.
Collectors and curious kids both get a kick out of it. Hold a raw stone next to the drawings and try to name its system.
What's on it
- Side one: What defines a crystal system, plus four factors that shape a crystal's size and form.
- Side two: All six crystal systems with axis rules, line drawings and example stones.
How to use it
- Open it next to a mineral ID book or app
- Print it for a classroom or homeschool lesson
- Pair it with the Crystal Shapes guide for meanings
Care: Keep the file in a folder you'll remember, and print on heavier paper if you can.

Good questions
Which crystal systems are covered?
Six: cubic, tetragonal, orthorhombic, hexagonal, monoclinic and triclinic. Each has a short description of its axes and angles plus line drawings, and most list example stones.
Does this guide cover crystal meanings?
No. It sticks to the mineral science: how crystal structure works and what affects a crystal's size and shape. Pair it with the Crystal Shapes and Their Meanings guide for that side.
What's the difference between print and PDF?
Print is a sturdy double-sided card (about 6.3 x 9.4 in) that ships with your order. The PDF is the same two pages as a file you can download right after checkout and print at home.
