What Is a Rounded Diamond Called?

A rounded diamond is also a circular diamond or a brilliant cut. Its shape is the primary reason for its name. Round-cut diamonds were initiated in mid 17th century when cutters learned to use advanced techniques.


Before their transformation, round-cut diamonds went through different processes. The first known round diamonds were known as old European cuts. They were circular but much different from the modern-day Round cut diamonds.


Round brilliant cut diamonds have 58 facets. They gained popularity in 1919 when Marcel Tolkowsy formed a theory about diamonds and their behavioral characteristics in the presence of light. These round diamond shapes changed, transforming from point diamond cuts to old cuts and modern cuts.

Point Cuts

Point-cut diamonds were famous during the middle age. However, there wasn’t much to do in their cutting technique since the diamond cutters lacked appropriate knowledge and necessary machinery. Instead, they maintained the diamond’s shape and polished them, transforming them into point cuts. And their symmetrical facets resulted in their sparkle.

Old Cuts

During the industrial changes, more advancements occurred, leading to a relative improvement in diamond technology. That helped cutters be more precise in cutting techniques and diamond shapes, leading to another development, the bruting procedure. Later on, diamond cutters could form the European cut style, which still exists and is an excellent option for antique jewelry.

Modern Cuts

Marcel Tolkowsy, mentioned earlier, introduced the well-known round brilliant cut using a mathematical formula. Fortunately, modern-day tech development helped to improve it to perfection.

The old European cut was similar to round cut diamonds but now contrasts each other in:


  • Their table size now differs as the European cuts have tables smaller than round cuts.
  • European cuts lacked precision and appropriate cutting technique due to their crude inventions, unlike round cuts, which result from modern-day diamond cutting innovation.
