Point Cuts:


Diamonds of these cuts were famous in the middle ages. These jewelers lacked knowledge and technology hence were unable to cut diamonds. They rather conserved the shapes of these diamonds and polished them to pointcuts. 

However, they had symmetrical facets hence creating more sparkle from it.


Old Cuts:


With the progression of the industrial revolution, diamond technology improved relatively, giving diamond cutters more precision with their cuts, resulting in the ability to form a thin girdle (bruting process).

Soon, cutters were able to create the old European cut. They are a good choice for antique rings today.


Modern Cuts:


Marcel Tolkowsy originally invented the modern round brilliant-cut with a mathematical formula for cutting diamonds proportionally. Thanks to advancements in technology, his instruction has been modified to perfection over time.


An old European cut used to be a type of round cut diamond, but they now differ in:


  • Table size:  Old European cuts have smaller tables, while round-cut diamonds are known for large tables.


  • Facet Shape: An old European cut has a triangular facet, while a round diamond has thin facets of different shapes.


  • Precision and Symmetry: Contrary to recent round brilliant cuts, old European diamonds are not symmetrical and precisely cut since they were cut crudely before modern inventions.


The color against brilliance:


Round cuts are to display a diamond’s brilliance. Contrarily, the visibility of color is the basic design for European cuts.
