As rare as they are, diamonds actually lose about 50 to 60 percent of themselves during the shaping and polishing process. This means that any real diamond you hold has gone through an extensive and careful method of getting into the shape you hold.
Plutonium is a radioactive chemical that is used in the creation of nuclear weapons and nuclear reactors. With as much intrinsic power as it has, you can imagine just how expensive it would be. And yet, diamonds are more valuable than plutonium per gram.
Diamonds are usually measured in carats and of course they become more expensive as the carats go up. But there is a notable jump when a diamond breaks through the 5 carat, 10 carat and 20 carat brackets—and there are very few items that go beyond 20 carats.
The shape may be the same and one might look identical to another to the untrained eye, but a diamond is very much like a fingerprint. When you’re holding one, there is not one other diamond in the world like it.
Once upon a time, the world didn’t understand colored diamonds. But now we know that colored diamonds are rarer and therefore more valuable than the more common white diamond. Likewise, there is an art to the coloring. It can’t be too light, but it can’t be too dark either.
