The Round diamond is considered superior to the fancier diamond shapes because of the breath-taking sparkle it provides. This is because virtually all Round diamonds are brilliant cut, which ensures maximum light reflection and brightness. Because of this, it is hardly surprising that the Round diamond is the most popular of all cuts, accounting for more than 50 per cent of diamonds sold worldwide.
Please note that when we refer to the diamond ‘cut’ in terms of the diamond’s shape, it is not to be confused with the diamond’s actual cut, which refers to the proportions of the diamond and how well polished it has been from the raw material. You can discover more about this by heading to the cut section.
Round Brilliant Diamonds
1. An Introduction
The Round diamond is unique because the proportions of this cut maximise fire and brilliance. It is extremely versatile, boasting a timeless and classic design. If you are struggling to choose an engagement ring for the lucky lady in your life, this is a safe bet. There are many examples of this diamond in history, but it wasn’t until 1919 that the modern Round Brilliant diamond was created.
The Round Brilliant cut is the most researched in history and it accounts for the most diamonds sold. For many, many years, diamond cutters have been attempting to optimise the brilliance and fire of this diamond by using precise mathematical calculations and advanced light reflection theories. What we are left with is a diamond that features 58 facets, or 57 if the culet is pointed, which are divided amongst the pavilion, girdle, and crown. It has a length/weight ratio of 1.00 -1.02. This cut naturally follows the rough diamond crystal, which yields maximum shine.
3. Buying Advice
This diamond shape can be traced back to Ancient Hindu texts, when Indian fishermen would discover loose stones in the streams and rivers below the Himalayas. However, the real origins of the Round diamond cut can be traced back to the 17th century, when they were known as Mazarins. This is when more complex and refined diamond cutting techniques were used. As time went by, this diamond shape developed further.
Nevertheless, the Round Brilliant cut like we know it today did not come about until 1919 when a noted engineer and diamond cutter, Marcel Tolkowsky, published a particular mathematical computation of proportions and angles to create optimal fire and brilliance. This is why the Round Diamond can also be called the Tolkowsky Ideal cut.
