During a deep-space expedition to an ancient rogue comet, an autonomous survey probe retrieves a crystalline mineral named celestite-X. The substance does not conduct electricity in either its solid form or its molten state, and it demonstrates extreme hardness alongside an exceptionally high melting point exceeding 3000 °C. Analytical spectroscopy reveals that the sample consists entirely of nonmetal atoms interconnected by continuous, directional electron sharing throughout a three-dimensional lattice. Based on these observed properties, which classification describes this crystalline solid?
