How Diamonds Are Cut Into Shapes


Diamonds are cut into shapes with a laser, saw, and/or steel blade. A groove is first cut, then the diamond is split with the blade. Sawing refers to when a diamond saw is used to cut a large diamond into a few different pieces, which a laser can also do. This is what gives diamonds their main shape before going more into detail. When it comes to cutting diamonds, there are three main facet structures. These include brilliant-cut, step-cut, and mixed cuts. Just as with natural diamonds, lab grown diamonds are grown as a rough, often in a rectangular shape. This actually makes round diamonds more affordable to cut than with natural diamonds.


Difference Between Diamond Shapes and Diamond Cuts

The diamond shape is the outline of the diamond. This is their geometric shape, such as round, rectangular, square, octagonal or oval. It is the most general way to define a diamond cut.

A diamond cut is a type of science, much more elaborate than the shape. It takes into consideration angles, distances, and light. Well-cut diamonds have the perfect balance of brilliance and light, along with their levels of shadow.
