Differences between brilliant and diamond

In the jewellery world, the terms “diamond” and “brilliant” are often surrounded by some confusion, but at diamonds.com, we make a clear distinction between the two to provide guidance and help you understand their fundamental differences. A “diamond” is the term used to refer to the gemstone in its natural or cut state, regardless of its shape. It is, in essence, crystallised carbon that, under conditions of high pressure and temperature in the earth’s mantle, is transformed into this exceptionally hard and brilliant gemstone.

On the other hand, “brilliant” refers specifically to one type of diamond cut, the round brilliant cut, which is the most popular and recognised style for these gems. This cut is characterised by its 57 or 58 flat faces (including the cusp), which are strategically designed to maximise the refraction of light, producing the unparalleled sparkle and brilliance that make diamonds so coveted. The brilliant cut is optimised to enhance the brilliance of the diamond, i.e. the amount of light that is reflected back to the eye of the beholder.

At diamonds.com, we want to put on record, that while all brilliants are diamonds, not all diamonds are brilliant. This distinction is crucial when choosing a piece of jewellery, as the type of cut directly affects the appearance, brilliance and ultimately the visual impact of the gemstone. In addition, while the brilliant cut is highly valued for its ability to enhance the light and colour of the diamond, there are other cuts such as princess, emerald, and oval, which offer different aesthetics and light reflections, providing a diversity of options to suit each individual’s personal tastes. Ultimately, at diamonds.com, we urge buyers to consider both diamond type and cut style when making decisions, as both factors play important roles in the beauty and value of the jewellery selected.


¿Qué es la Escala de Dureza de Mohs?

What is the Mohs Hardness Scale?

The Mohs hardness scale is a method of classifying minerals based on their resistance to scratching. Created by German mineralogist Friedrich Mohs in 1812, this scale remains a standard in geology and mineralogy for measuring the hardness of minerals and other materials. Understanding this scale is essential not only for geologists but also for jewelers and mineral collectors, as it provides an easily comprehensible reference for the durability and resilience of materials.
