Gemforge – Crystal Generator for Blender

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.

What you get

• 64 ready-made designs: amethyst clusters, citrine and smoky quartz, cathedral geodes, agate geodes, pyrite, bismuth, fluorite, desert rose, kyanite, glowing fantasy crystals and more
• 15 crystal shapes and 6 formations: cluster, druse, geode, single point, spray and outcrop
• About 45 minerals with photoreal clear, gem, opaque and metallic materials: color zoning, milky roots, inclusions, striations, iridescence and glow
• 8 host rocks with photo-scanned PBR textures (color, roughness, relief), broken fracture shapes and mica sparkle; agate bands on geodes
• One-click randomize: new layout, variation, mineral or a surprise design
• Picture pickers for every visual choice, live editing in the sidebar
• Looks right in EEVEE and Cycles
• Game ready: one mesh with three PBR materials, a Low detail setting and attributes that bake to plain texture maps

Requires Blender 4.2 or newer. Tested on Blender 4.2, 4.5 and 5.2 LTS.
