Diamond vs Pearl


Pearls and diamonds are both beautiful, expensive and sought after, but what's the difference between them? Let's take a look.




First of all we need to get one thing straight: a pearl is not a diamond. They are very different - one consists of calcium carbonate and the other is a mineral. But if pearls aren't diamonds, what are they? Pearls are found inside oysters in much the same way as a diamond forms deep below the Earth's crust. A grain of sand gets lodged in an oyster causing irritation, so the oyster tries to cover it with something smooth and iridescent. It's this reaction that causes pearls to form!

Diamonds, on the other hand, are carbon and emit a fiery sparkle. They're formed underground when dead plant matter gets squashed between rocks until it turns into pure carbon. When this carbon suffers immense pressure deep in the Earth's crust - about 100 miles below the surface - it forms a diamond!




Natural pearls are far more difficult to find than diamonds, owing to the fact that they are harvested by skilled divers in deep water. This is a very dangerous endeavor that exposes divers to marine hazards such as stingrays, sharks, sawfish, etc.

Diamond mining, on the other hand, is a far safer task. Deep in the Earth's crust they are either brought to the surface by volcanic eruptions or mined by digging underground tunnels out of which diamonds are dug up.




Pearls were formerly quite uncommon until scientists figured out how to cultivate pearls in oysters. Once experts discovered how to produce pearls in oysters, the market was flooded with them, driving prices down.

On the opposite end of the spectrum, one of the popular misconceptions about diamonds is that they are incredibly rare. This is not true. Diamonds are plentiful, but their scarcity is maintained or enhanced by strict industry control. The controlled scarcity levels maintain or raise prices accordingly.

Realistically, there are plenty of diamonds available in the world. However, colored diamonds are considerably more uncommon, with red, blue, and pink being among the rarest and most valuable.




Diamonds have a reputation for their breathtaking shine and ability to interact with light. They're generally cut to increase their radiance. When light shines on a diamond, it bends and refracts, making it appear very sparkling.

Pearls, on the other hand, are valued for their color and lustre, which is pearlescence. The sheen of pearls results from light bouncing off the nacre crystal and reflecting back to the viewer's eye.




It's impossible to say which is more costly, pearls or diamonds because they're both valuable in their own unique ways. Some pearls are worth more than some diamonds, and vice versa, with several variables influencing the value of each pearl or diamond.

In general, since most pearls are cultivated, you may discover that they are less expensive than a lot of diamonds. Natural pearls, however, are quite rare and valued more than many diamonds on the market.




Pearls are unique. Each pearl is unique; there are minor flaws, such as bumps, ridges and clips that serve as fingerprints to distinguish them from each other. In terms of baroque pearls, each stone has its own identity.

The majority of diamonds, however, are quite similar once cut and polished, making it impossible to tell one from the next. You won't see irregular-shaped diamonds in jewelry shops unless they're unpolished.




Pearl jewelry is typically durable and long-lasting. Of course, the type of pearl you purchase will determine its durability. Natural pearls are very strong, although prone to scratching. Whereas, imitation pearls are not as strong.

Diamonds, on the other hand, are quite hard and resistant to scratching. However, because they're so hard, diamonds are also brittle and may shatter or break from a sudden blow or shock.




It's easy to care for your pearl jewelry with just a little bit of tender loving care. Don't expose your pearls to harsh chemicals, such as chlorine and bleach, or extreme heat or cold temperatures. Ideally, you should keep them away from lotions and perfumes.

Not only is it easy to care for your diamond jewelry, but you should do so because diamonds are brittle and may break if dropped or knocked. You should store them separately from other pieces of jewelry and wrap them in a soft cloth or paper whenever you plan on storing or traveling with them.




While pearls and diamonds are both valuable, each has its own characteristics that will impress buyers. You can't go wrong with either stone as long as you select the one that best matches your preferred style and budget.

Diamonds and pearls each have their pros and cons, but both will make a fine addition to your jewelry collection.
