Overall Assessment
This specimen is likely not a diamond, but a blue mineral such as Lapis Lazuli, Sodalite, or glass slag, given the conchoidal fracture and texture.

Interesting Facts
The intense blue suggests a high concentration of sulfur or boron if it were diamond, but texture indicates a silicate mineral.
