Some clever gents gently broke buckyballs "to form a disordered nano-clustered graphene-based hard phase with more than 90% elastic recovery after deformation", a novel amorphous material with extraordinarily high hardness and compressive strength:

From what I can tell this creates layers of graphene-like platelets with enmeshed edges. Now that we know what it looks like, maybe it can be synthesized from graphene rather than buckyballs, for slightly more economical mass production.
