crystal shard 3d model

A close-up photograph of a powerful ancient artifact shaped like a fractured cosmic crystal. The artifact is made of deep sapphire and cyan glass-like material, shattered into several large, jagged shards that are miraculously held together by glowing, electric-blue magical energy tendrils. The edges of the fractures are sharp and raw. Inside the core of the broken crystal, a bright, pulsating arcane light source emanates. The crystal surface is covered in faint, glowing ancient runes. The artifact rests on a dark, weathered stone altar with dust and moss. Dramatic moody lighting, cinematic composition, volumetric rays, octane render, 8k, highly detailed texture, unreal engine 5.
