Diamond Cutting In Amsterdam

Diamond cutters have been part of Amsterdam’s industrial landscape since the 1500's.
As the diamond industry developed, Amsterdam led the way in many technical and aesthetic innovations.
Today Amsterdam is still a vibrant centre of the diamond trade and is proud of its long and illustrious tradition.

Old Mine Cut

In the distant past, diamonds were simply left in their natural shape and polished. However, during the 1400s, technologies were discovered for cutting diamonds, making it possible to increase the number of facets and create symmetry. The result was the Rose Cut, a flat-bottomed, dome-shaped cut with up to 24 facets.

Over centuries, the Rose Cut evolved through a number of intermediate forms, the most enduring of which was the earliest modern brilliant, The Old Mine Cut.
Round Brilliant Cut

Although the number of facets was still limited compared to later brilliants, The Old Mine Cut remained a common and popular cut until the turn of the twentieth century. However, the advent of mechanical cutting and other technological innovations, allowed early twentieth century cutters to experiment with new ways of enhancing the fire and brilliance of the stones. The result was the familiar Round Brilliant Cut.

These brilliants were essentially rounded rectangles or squares, also known as Cushions Cuts. The crown was still relatively tall, with a small top surface, or table.

Cutters continued to improve their techniques, and by the 1800s, a diamond’s value was now determined by its “fire,” or the way light is reflected by its facets.

The Round Brilliant Cut is characterized by its circular shape, its larger number of facets, its lower crown and larger table.

In the course of the twentieth century further innovations followed, culminating in computer-aided cutting technologies that minimized wastage and maximized the fire and brilliance to previously unimagined levels.
By the late twentieth century, it seemed the boundaries of what was technically and aesthetically achievable had been reached.
