Twenty identical triangles make up an icosahedron, one of the five Platonic solids, and these clear quartz versions turn that geometry into something you can hold.
Each icosahedron is cut from crystal quartz with high clarity and a few natural crackle inclusions that catch the light, so they work as sun catchers on a bright windowsill. They also sit neatly on a desk, a bookshelf or a sacred geometry grid. Sizes step up from about 2.25 inches for 1 to about 3 inches for 4, and the larger ones show more depth through the faces. They make a good gift for a math lover, a geometry fan or a crystal grid builder. You choose the exact piece from the photos.
Each numbered option is pictured on its own, so the piece you see is the piece you receive. All four are close to even on every side, from about 2.25 inches for 1 to about 3 inches for 4. Look at the ruler photo for scale.
About Quartz Icosahedrons
A regular icosahedron has 20 equilateral triangle faces, 30 edges and 12 corners, and it is one of the five Platonic solids. In the Timaeus, Plato linked it with the element water. Clear quartz is silicon dioxide, a hard mineral that takes a brilliant glassy polish.
Stone Meaning: Clear quartz is traditionally associated with clarity and focus.
