When we think about diamonds, we usually have on our mind a sparkling crystal that you have to notice. This isn’t always the case because there are different levels of brilliance. There are various factors that will determine the shine, but the amount of facets is one of the most significant. The cut contributes to the brightness and for that round shaped stone looks the best. It has 57 or 58 facets, and because of that, the light reflection is greater.
Interesting thing is that round type doesn’t have the matching effect on color diamonds. Besides that, it is harder to make it into this cut. You can find a full list of shapes here if you are looking for other types. Every cut has its own story and process on how it is made. A lot of time is invested in getting the rough stone and making it into something elegant. Your taste matters the most, but other factors set the price.
Round Diamond History
This type of diamonds exists for a long time, but there were many changes made. A new method to cut them and make them incredibly brilliant was created by Marcel Tolkowsky in 1919. He used many kite-shaped and triangular facets that scatter outside from the middle of the stone. Before he discovered this, they were present, but with less brilliance. One of the most interesting round cuts made in the 1800s was The Old European Cut.
This diamonds had slightly large culet size, a lower half facet range less than or equal to 60 percent, a crown angle larger or equal to 40 degrees, and much smaller tables. We are now able to grade the stone which wasn’t done when this one was created. That is why it is important to separate the Old European Cut and a badly shaped round brilliant since the latter need to be given a bad cut grade when the earlier will only be graded based on clarity, color, and carat.

While Tolkowsky is accountable for establishing this type of cut, it didn’t end evolving at the beginning of the 20th century. The one that we have and love now has developed considerably over the years. If you want a round shape with most facets, that would be 58 facets which can be an upper half facet, a star facet, and bezel facet. There are modern round stones with 57 facets because they have a culet. This means that there is a tiny pointed section at the bottom of the diamond.
Because of their great look and popularity, this type of stones is actually 75 percent of all the sales. But, because of this, the price goes up. Other fancy shapes are usually 25 to 35% cheaper than round diamonds. When you compare it with emerald or princess shape, you will notice that it is more durable than these types.
Another reason why they are more expensive is that they don’t have sharp edges meaning that there is no risk of getting damaged at the corners. All types are polished and cut from their primary rough form. A big part of the rough stone is removed when it comes to creating round diamonds. Because there is more work to be done, and because from a bigger rough stone you get something much smaller, the price goes up. The end shape is a product of a delicate and lengthy process that requires patience, experience, and skill.
Some of the Most Expensive Diamonds
The Graff Vivid Pink Diamond is worth around $46 million. The value is this high because of its natural pink color. One of the most famous stones in the world is The Hope Diamond which appraised value is about $200 million. It has a rich history because one of the owners was King Louis XVI.
There are also some stones that can’t have the right value. The Koh-i-Noor has 105.6 carats discovered in 1294. The meaning behind the name is a mountain of light which was taken from the Persian language. The price of this stone is unknown, but there are some professionals that think it can be over 1 billion euros. There might some that are even more expensive but yet to be discovered.
