Why these Diamonds are more expensive/valuable 

You may be wondering what makes these diamonds so valuable that they are incredibly expensive. Well, diamonds naturally are precious gemstones that are highly valued for their rarity. In fact, they are one of the most sought-after natural possessions in the world. Apart from this, other factors determine why these diamonds are so valuable, and we will look at a few.

First, to identify the value of a diamond, you have to think of the number of carats it weighs. Weight plays a huge role in the value and expense of a diamond. Diamonds that weigh more are often large and difficult to find while mining since they could lose their original form in the process.

What’s more, the time and complex nature of the finished work on a particular gemstone will also add to the price and increase the value. In addition, since jewel collectors will pay a fortune to own some of these beautiful gemstones, jewelers are more than willing to spike the price.

Other factors that make a diamond so expensive and valuable are the clarity of polishing, the number of flaws found in the natural stone, the historical value, and previous owners’ status.

For instance, if a diamond formerly owned by a royal family or a celebrity is auctioned, the value of that diamond will also increase. Diamonds are beautiful and rare, so it is not out of place that some are extremely expensive.
