Explore diamond cuts, from its historical origins emphasizing weight and symmetry to today’s super-ideal diamonds maximizing brilliance. This Brigthtguide full guide takes you on a journey from the earliest ways to cut a diamond, when keeping the weight and keeping the symmetry of the diamond’s rotation was important, to the present day when super-ideal diamonds are used to get the most light return and shine.

We’ll look at how different cuts, like the classic emerald and step-cut stones and the current brilliant-cut stones, have changed over time. So, whether you’re a beginner or an expert, get ready to learn how the cut affects not only how these valuable stones look but also how much they’re worth.

Key Takeaways

  • Diamond cuts have evolved over centuries, from early octahedral forms focusing on weight preservation to today’s super-ideal cuts maximizing brilliance.
  • The history of diamond cuts includes shifts from less symmetrical cuts to more symmetrical arrangements, resulting in brighter and more beautiful diamonds.
  • Over time, understanding pavilion depth and critical angle of cuts reduced light leakage, leading to diamonds with better internal reflection and standardized grading.
  • Today’s super ideal diamonds represent the pinnacle of cutting, emphasizing perfect ratios, symmetry, and facet arrangements for maximum brilliance.
  • When selecting a diamond cut, consider budget, personal preferences, table size, pavilion depth, and the impact on brilliance and value, while understanding the Four Cs (cut, carat, color, and clarity).

Diamond as Rough Stones

The earliest form starts in the 10th century and goes right up to the present day. In the 10th century, diamond polishers predominantly worked with the octahedral crystal form, emphasizing weight preservation and showcasing the diamonds’ natural beauty through rotational symmetry, 10-fold symmetry, and 12-fold symmetry.

This was a time when the table size and table facets were not as meticulously crafted as they are today, but the focus was more on the diamond’s natural characteristics. Shapes changed by the middle of the 16th century, laying the groundwork for the beautiful cut stones we see today. These cuts made the facet arrangements more symmetrical, which made the diamond shine brighter.

The diamond-cutting process evolved to include a wide range of shapes, from the classic emerald cut to the romantic teardrop shape. By the time we reached the era of rose-cut diamonds and mogul-cut diamonds, light leakage had become a critical factor to consider. Advances in understanding pavilion depth and the critical angle of cuts led to diamonds with better internal reflection, reducing light leakage significantly.

Why it’s important to have a professional cut your diamond?

Arrangements of the facet diamonds and perfect symmetry are two of the most important parts of making a beautiful diamond. Getting the pavilion angles, upper girdle facets and girdle irregularity just right are all important parts of making diamonds that sparkle incredibly.

Excellent cut diamonds meet the highest standards for diamond cut, which makes them shine and sparkle like nothing else. If you cut a diamond too shallowly or too deeply, it can lose its shine. The right proportions let light into the diamond and reflect it back out, giving it the most fire and sparkle.

When judging the proportions of a diamond, these four things are very important:

  • Table Facet: The table facet is the big, flat part on top of the diamond. Its size affects how light comes in and goes out of the diamond. 
  • Pavilion Depth: The pavilion depth is the distance between the bottom of the girdle and the culet of a diamond.
  • Step-Cut Stone: For step-cut stones like emeralds and Asscher cuts, proportions are very important. For these cuts to have the best hall of mirrors effect, the exact arrangement and proportions of their step-like facets are very important.
  • Table Ratio: This ratio changes how the diamond looks when it is held up to the light and can affect how well it is cut overall.

Effect of Cuts on the Price of Diamond

Getting the perfect diamond cut has a big effect on the price of a diamond because it determine how beautiful and bright it is. This list shows four main things that show how diamond cut affects price:

  • Diamond Cut: The grade of the cut has a direct effect on the beauty and value of a diamond. A well-cut diamond reflects light as much as possible, which makes it sparkle and look more appealing.
  • Carat weight: Diamonds with a higher carat weight typically cost more. A well-cut diamond with a lower-carat weight can still be beautiful to look at and worth a lot of money.
  • Popular Diamond Shapes: The round brilliant and princess cut diamond shapes are two of the most popular and sought-after diamond shapes. The price of these diamond cuts may change because they are so popular.

Choose Your Diamond Cut

The choice of diamond cut affects the final appearance. Cutters must consider diamond characteristics and choose a cut that highlights them. Mogul-cut diamonds are a unique and lively stone, while round brilliant and princess cuts are popular standard diamond cuts.

Grading Standards

Diamond cut grading standards evaluate diamond cuts. These guidelines examine the pavilion facets, pavilion step-cut, and pavilion terminus. Paying attention to these aspects results in a magnificent diamond with excellent balance and brilliance in the finished stone.

Brightness, Symmetry

Diamond cutting is art because of balance and symmetry. An 8-fold symmetry is desired since even a tiny difference might result in a noticeable difference in size and internal reflection of light. Keeping carat weight while enhancing shine is tough but required.

Magic of Inner Brilliance

One of the miracles of the process of diamond cutting is the creation of interior brilliance. The spectral colors that dance inside the stone become apparent due to internal reflection and light scattering. Diamonds are more gorgeous because of the colored light created by meticulous cutting.

Compare Classic and Unique Outlines

Diamond cutters can form gems normally or uniquely. Asymmetric outlines, like the octagonal outline, give something distinct and current to the classic outline, which is popular since it lasts for a long time.

The process of diamond cutting is complex, and the range of quality in the finished stone might vary. Differences in size, form of step-cut stones, and accent stone choice can all alter the outcome.
