Diamond cut: shapes, types, quality & formation – Kapitalanlage Edelstein

Diamonds are known to have the unique property of refracting light in such a way that it intensely sparkles, reflects, bends and scatters light. There is no comparison. That’s why the value of diamonds continues to rise. Today, 1 carat (0.2 gram) will cost you 7,116.17 USD or 5,990.54 EUR. Besides the brilliance, the cut determines a large part of the purchase price. There are different shapes of cut diamonds, 21 of which I want to introduce to you today. To the cut forms belong for example round cut (also brilliant cut), heart, oval, marquise, radiant and princess (princess cut). The cut quality significantly determines the value of a diamond. When determining the value, it is all about how well the facets of a diamond interact with the light.

Diamond Cut: 21 Shapes & Types

The cut of a diamond is crucial to the final beauty and value of the stone. Of all the 4Cs of diamonds, the cut itself is the most complex and technically difficult to analyze.

These factors make it possible to evaluate how successfully a diamond interacts with light to produce desirable visual effects such as:


Inner and outer white light reflected from a diamond.

Sparkle (light refraction)

The scattering of white light into all the colors of the rainbow.


The amount of sparkle a diamond produces and the pattern of light and dark areas created by reflections in the diamond.
