Grow realistic crystal clusters, geodes and mineral specimens in one click, right inside Blender.

Gemforge builds every crystal from real crystal habits: six-sided quartz points with their rhombohedral tips, double-terminated Herkimer points, calcite dogtooth, selenite blades, pyrite cubes, fluorite octahedra, garnet dodecahedra, stepped bismuth hoppers and more. The crystals grow on a real host rock, line the inside of a cut geode, fan out as a spray or break out of the ground as a giant outcrop.

64 crystal designs
Amethyst, citrine geodes, pyrite, bismuth, emerald, selenite and glowing fantasy crystals. One click each.

45 minerals, one click
Swap the mineral and the same cluster turns into clear quartz, amethyst, ruby, aura quartz, pyrite or a glowing crystal.

A new layout every click
Randomize the layout for a fresh arrangement of crystals and rock, with the same design and colors.

Drag a slider, watch it grow
Every setting rebuilds the cluster live in the sidebar: here the crystal length slider.
