4 Different Diamond Cuts Beginner Jewellery Collectors Should Know
A diamond can have different cuts for different designs. Experts can quickly differentiate these cuts. It is safe to say that years of experience have made them experts in the field. However, if you have just started collecting jewelry then you must know the basics. A cutter considers various variables before proceeding with the cut. These variables are as follows:
- Original shape of the stone
- Location of internal flaws or inclusions
- Preservation of carat weight
- Consumer preferences
What are the cuts of these diamond ring designs? Let me give you a rundown.
Round Brilliant Cut
The round brilliant cut is considered as a standard cut for diamonds. If you encounter one and are knowledgable about math and proportions, you will notice that the facet arrangements and proportions are mathematically precise. This is because these cut have been computed and perfected by mathematical and empirical analysis. This shape is not circular, contrary to its name. The modern version has 58 facets (57 if the culet, a flat face on the bottom of the diamond, is excluded). The top half of the gemstone may be frosted, polished or faceted depending on the buyer’s preference. This cut is common in most engagement rings as its appearance is considered timeless. Modifications such as the hearts and arrows phenomenon and the passion cut is offered to those who want different round brilliant diamond ring designs. There are also modified brilliants which, as the name suggests, modifies the cut into different shapes.
Round brilliant cuts are the preferred cuts when the crystal is an octahedron. When the crystal is oddly-shaped, the cut will more likely be in a fancy cut. Fancy cut diamond ring designs are grouped into different categories: step cuts, mixed cuts and rose cuts.
Step cuts are administered to stones whose outlines are either rectangular os square-shaped. The facets are rectilinear and arranged parrallel to the girdle. It is important to notice that the pavilion and crown of the step cuts are shallow. Thus, stones cut this way are not as bright as round brilliant cut stones. But the cut also accentuates the clarity, whiteness and lustre of the stone. Variations to the step cut design are based on commercial preferences.
Mixed cuts are, well, a mixture of different cuts, normally, step cuts and brilliant cuts. A typical mixed cut has the crown of the gemstone having a brilliant cut and the pavilion having a step cut. The mixture is meant to combine weight preservation and dimensions found in step cuts with the optical effects common in brilliant cuts. This lets the diamond ring have the best of both worlds.
Rose cuts are rare nowadays. However, if you spot one, you will notice its flat base and a crown of triangular facets which rise to form a point. A diamond with a rose cut design is considered an antique.
