Rolled Lip: The leading edge features a distinctive metallic curled lip, formed when molten iron was swept backward by supersonic airflow and instantly solidified—a direct physical record of its flight path.
Flow Lines: The fusion crust is covered with sharp, dense, parallel flow lines, especially on the sides and rear. These linear textures were created as molten surface material stretched and solidified under aerodynamic shear, precisely indicating the direction of flight.

3. Scientific and Collectible Highlights
Historical Significance: The 1947 fall event was systematically documented and studied, forming a cornerstone of modern meteoritics and providing a complete scientific chain from orbital calculation to recovery.
Aesthetic Paradigm: Oriented Sikhote-Alin individuals are celebrated as the "pinnacle of meteorite beauty," blending fluid form, a lustrous fusion crust, and delicate flow lines into a natural sculpture of cosmic violence.
Research Value: An ideal specimen for studying atmospheric dynamics, ablation processes, and mass loss of meteorites. Its oriented features serve as an intuitive model for understanding the entry of extraterrestrial material into Earth's atmosphere.
Rarity: Although the total recovered mass is substantial, individual specimens with such distinct and well-preserved oriented features remain scarce and highly sought-after in the collector's market.
