Betafite Crystal

thingiverse

Betafite, a sought-after uranium mineral, is known for forming attractive, well-shaped crystals. This unique mineral crystallizes in the isometric symmetry class and can yield large octahedral and dodecahedral crystals weighing up to 100 kg. However, these crystals may be modified by other isometric forms or flattened when two dominant faces are present. Superbly shaped betafite crystals are highly valued in collections!
