[Crystal] Mineral Textures

Mineral crystal textures capture the raw, unpolished structure of natural quartz — internal fracture lines, cloudy inclusions, and uneven crystalline growth rather than a cut, faceted gem. It's the look of a specimen pulled straight from the ground.

What's in this collection

• Clear mineral quartz — translucent surfaces with visible internal fracture lines.
• Cloudy mineral quartz — milkier, less transparent variants with soft internal diffusion.
• Natural growth patterns — uneven ridges left by unrefined crystal formation.
• Detailed close-up sets — high-resolution surface detail for hero-shot renders.

All tiles are seamless in both directions and delivered at high resolution.

Where Mineral Crystal is used

Jewelry and product visualization. Raw-stone product shots and packaging mockups.

Game environment art. Cave systems, mines, and fantasy crystal formations.

Science and education content. Geology visuals and mineral identification material.

Interior design renders. Decorative stone accents and display pieces.

How to use these in Blender

1. Connect the base color map to a Principled BSDF and enable transmission for translucency.
2. Use the grayscale map as a normal input to capture the internal fracture detail.
3. Lower roughness slightly for a natural, semi-polished mineral look.
4. Light from behind or the side to reveal internal structure through transmission.

How to use these in Unreal Engine 5

1. Build a Material with base color, normal, and roughness maps.
2. Enable subsurface or refraction settings for a translucent, gem-like result.
3. Add a Material Instance to vary clarity and tint across different assets.
4. Check the look under both direct and ambient lighting setups.

How to use these in Unity

1. Assign the maps to a Lit material's albedo and normal slots.
2. Use HDRP's translucency or subsurface settings for internal light scattering.
3. Tune smoothness so the surface reads as natural stone, not polished glass.
4. Test under a strong key light to confirm the internal fractures read clearly.

Tips for Mineral Crystal specifically

Unlike cut gems, mineral crystal surfaces should stay irregular — avoid perfectly symmetric facets, which read as artificial.

Backlighting sells translucency far better than front lighting; place a light source behind or inside the mesh if your engine supports it.

Slight color variation across a single piece, rather than one uniform tone, matches how real mineral specimens actually look.
