Hard disagree: they exhibit 4 perfect octahedral cleavage planes in addition to their adamantine lustre, diamond is one of the most useful materials in existence, and their petrological origins speak to incredibly interesting conditions of formation! In fact, a mineral inclusion within a diamond gave us our first solid evidence of the existence of water at equilibrium with mantle rock at depth on Earth, which was previously largely discounted.
That’s because diamonds are pretty boring. The only thing they have going for them is sparkling. There are SO many prettier gemstones out there.
