Laser Diamond Cutting

What are the advantages of laser Diamond Cutting compared with the traditional way?

Precision and Accuracy:

Laser cutting allows for extremely precise and accurate cuts, enabling intricate and customized designs with minimal errors. The focused laser beam can create fine details that are challenging to achieve with traditional methods (Dhanak & Badini, 2008).

Reduced Waste:

Laser cutting minimizes diamond wastage as the laser can be carefully directed to maximize the yield from a rough diamond. This reduces the loss of valuable material (Jahanmir, 1999).

Less Risk of Damage:

Laser cutting generates less mechanical stress and vibration compared to traditional cutting methods, reducing the risk of damaging the diamond (De Silva, Das, & Ashby, 2009).


Laser cutting is highly versatile and suitable for a wide range of diamond shapes and styles, including intricate cuts like princess cuts and fancy shapes (Kaplan, 1998).


Laser cutting is considered a "green technology" as it uses minimal resources and generates less waste compared to traditional cutting methods, which involve grinding and sawing (Schuöcker, 2004).

Speed and Efficiency:

Laser cutting is generally faster and more efficient than traditional cutting methods, reducing production time and costs (Duley, 1999).


Laser cutting allows for greater customization and personalization of diamond cuts to meet individual customer preferences and design requirements (Dausinger, Lubatschowski, Schaffer, & Nolte, 2003).

Minimal Heat Affected Zone (HAZ):

Laser cutting produces a very small heat-affected zone, preserving the structural integrity and quality of the diamond (To & Sari, 2007).
