 Normally, we often hear about 57 - 58 facet diamonds, but have you ever seen a 100-facet diamond? So does having more facets make a diamond more brilliant? Let Jemmia explore 100-facet diamonds in the article below: 

What is a 100-facet diamond?

A 100-facet diamond is a diamond cut with 100 facets instead of the common standard cut of 57 or 58 facets (as in the brilliant cut – perfectly round). This is a special cut designed to optimize the diamond’s sparkle and light reflection, delivering superior brilliance compared to traditional cuts.

Thanks to having more facets, the diamond can reflect light in more directions, creating a greater sparkling effect. A 100-facet cut requires high craftsmanship and modern technology, so the manufacturing cost is usually higher.

Structure and cutting technique of a 100-facet diamond

A 100-facet diamond is crafted with a special structure, meticulously distributed across both the top and bottom of the stone. Typically, the upper part (crown) of the diamond has about 57 facets, scientifically arranged to optimize light reflection.

Meanwhile, the lower part (pavilion) has 43 facets, with angles and proportions carefully calculated to diffuse light back to the viewer’s eye, creating a dazzling sparkle and remarkable depth.

The cutting technique requires absolute precision from skilled artisans to ensure that each facet contributes to the diamond’s overall beauty.

Origin of the 100-facet diamond cut

The Cento 100-facet diamond cutting technique, developed by Italian jewelry designer Roberto Coin, was first introduced in 2003. After many years of research and collaboration with leading diamond cutters, he created a unique cut with a total of 100 facets - nearly double the traditional diamond cut with 57 facets.

He named the cut Cento - an Italian word meaning “100,” symbolizing completeness and perfection. Each Cento diamond has 37 facets on the upper part and 63 facets on the lower part, creating a brilliant and impressive light reflection effect.

Increasing the number of facets in the Cento diamond cutting technique aims to achieve three main goals: enhancing sparkle through optimal light reflection and refraction; creating an intricate symmetrical pattern like a blooming flower, helping highlight the diamond’s distinctive beauty; and elevating both aesthetic and artistic value through a complex crafting process and high technical requirements.

Outstanding advantages of a 100-facet diamond cut

100-facet diamonds stand out with exceptional advantages, offering perfection in both aesthetics and value. First, the greater number of facets gives the diamond superior sparkle and light-catching ability, creating dazzling light reflections that make the stone brighter and more captivating.

The strong visual effect under lighting is another advantage, as light is reflected from many different directions, creating a beauty that changes from every angle. In addition, the 100-facet cut structure also increases the stone’s depth and 3D beauty, giving it a vivid and impressive appearance, helping the diamond stand out and remain charming in every circumstance.

Notes when choosing to buy a 100-facet diamond

Below are the things you need to pay attention to when choosing to buy a 100-facet diamond:

  • Check the origin: Before deciding to buy, confirm the origin and documents related to the 100-facet diamond.
  • Consider the balance between the number of facets and overall quality (4Cs): Although a 100-facet diamond has impressive sparkle, you also need to consider the stone’s overall quality. Besides the number of facets, the factors in the 4Cs standard set (Carat - Weight, Cut, Clarity, Color) also affect the beauty and value of the diamond.
  • Examine the actual light effect carefully: Each diamond may differ in light effect depending on its cut and structure. Therefore, you should examine the diamond under many different light sources to accurately assess its sparkle, reflection, and light dispersion.
Note: For 100-facet diamonds, GIA reports usually only recognize the 4Cs parameters and do not evaluate cut quality according to GIA standards (because it falls outside traditional cut standards)

Frequently asked questions about 100-facet diamonds

Is a 100-facet diamond better than a 57–58 facet diamond?

Not necessarily. A 100-facet diamond has more light-reflecting surfaces, helping create a stronger and more multidimensional sparkling effect. However, actual “brilliance” also depends on cut quality, proportions, and symmetry. A properly cut 57-58 facet diamond can still be brighter and more beautiful than a 100-facet diamond if its cut quality is better.

Is a 100-facet diamond certified by GIA?

It can be, but GIA does not evaluate the 100-facet cut separately. GIA only certifies the 4Cs factors (Carat, Cut, Clarity, Color), and usually applies the Cut standard to the Round Brilliant cut (57–58 facets). For a 100-facet stone, a GIA report is still valid, but you should also check actual videos or internal certification from a reputable distributor.
