amethyst crystal 3d model

Create a 3D surface or asset using this exact texture style: marbled, organic purples with cloudy gradients, cracks, and irregular dark patches resembling chemically damaged film. Integrate amethyst-like crystal bursts emerging naturally from the surface—sharp, semi-transparent purple crystals, varying in size, clustered inside the darker regions. Maintain high detail, micro-cracks, subsurface scattering, and mineral sparkle. The model should feel like a hybrid between raw stone and cosmic film decay.
