Diamond cutting and finishing has seen many advancements over the past 100 years. As technology has developed, so to has the ability for diamonds to be crafted. 

The laser saw is one such technology that revolutionised diamond cutting when it was introduced in the 1930s. Many modern diamonds are cut using laser equipment which is far more accurate and efficient.

How Laser Sawing Works

The stone is mounted onto a dop so it can be directed through a laser beam. The burned graphite from the high-temperature laser leaves a black mark around both sides of the stone where the laser cut through. Because of this, these sides will then need to be polished. In certain cases, more weight is lost than would have been with conventional sawing.

The biggest advantage of laser cutting is the ability to cut with extreme precision. There is also no cutting edge to wear down, and lasers are less likely to warp the diamond because the heat is confined within a narrow space.
