The Classic Round Diamond

Also called the modern round brilliant cut, Marcel Tolkowsky developed the popular round diamond cut we are all familiar with today. His mathematical formula for cutting diamonds was 34.50% crown angle, 59.3% depth, and 53% table. Although this formula has been altered and perfected through time, the industry still sticks to Tolkowsky’s guide that brought us the first 58-facet round brilliant cut diamond in 1919.

These 58 critical facets are what make round cut diamonds highly coveted. More facets mean they can reflect light extraordinarily; thereby, creating those beautiful sparkles. For this reason, round cut diamonds are not only the most popular but also the priciest — it requires precision and skill because the dazzling fire and brilliance are reliant on precise geometrical formula.

Round diamonds are the most wearable diamond shape.

Next, remove the reflector and insert the diamond disc.

The GemLightbox Macro comes with three (3) loose stone discs in three (3) different colors to match the size of your loose stones.

  • Small disc for stones under 1ct
  • Medium disc for 1-10ct
  • Large disc for 10ct and above

The discs come in white, grey, and black.

For this tutorial, we will use the medium, black disc.


Step 3. Place the diamond on the disc.

Then, place the diamond on the black disc inside the GemLightbox Macro. Ensure the diamond is centered, especially when capturing a 360 video; otherwise, the diamond will be carried farther away from the center of the turntable when it rotates.

The disc has a groove mark. Place the diamond right on the groove to ensure that it is right in the center.

Put back the reflector.


Step 4. Adjust the width and height using the adjuster.
