Are raw diamonds worth anything?

I'm curious, are raw diamonds truly valuable? It's a question that's been asked for centuries, and yet the answer still seems elusive. On one hand, diamonds are known for their rarity, beauty, and durability, making them a sought-after commodity in the jewelry industry. But on the other hand, the process of mining, cutting, and polishing diamonds is both labor-intensive and expensive, leading some to question whether the final product is truly worth the cost. So, what's the real story behind raw diamonds? Are they truly worth their weight in gold, or are they simply a flashy bauble with little intrinsic value?
