Trilliant diamonds, also known as trillion or triangular-cut diamonds, are a beautiful and captivating alternative to the traditional round and princess cut diamonds. Their unique triangles and dazzling faceting make them lovely choices for earrings, pendants, and rings. Having knowledge of the geometry of trilliant diamonds is fundamental to understanding their intricacies and choosing the ideal one for your jewelry. 

Trilliant diamonds possess a triangular shape and consist of 50 to 60 facets painstakingly constructed to reflect maximum brilliance and fire. Their pointed corners and three equal sides form a bold, modern look which is ideal for both solitaire settings and as accent stones for engagement rings. 

There are two primary styles of trilliant diamonds: 

Brilliant-Cut Trilliant: This style has a large number of facets and features enhanced curved edges which improves brilliance and sparkle. 

Step-Cut Trilliant: Unlike the former, this variant has straight edges and a smaller number of facets. As a result, it has subdued elegant shine and a resemblance to emerald or Asscher cuts.

A trilliant diamond combines beauty with elegance through symmetry and proportions. It is essential that a skilled hand cut trillian diamonds: 

Maintains a depth of 32% to 44% which rests of his width for light reflection purposes.

A balanced triangle is formed with a length-to-width ratio of 1:1.  

To retain its shape, corners are rounded or chipped for unique designs.    

The Role of Faceting In Light Performance     

The specialized patterns of the trilliant cut produces a greater shine, which is why it was designed this way. The cut gives off a “crushed ice” effect where light reflects off several surfaces, creating an attractive sparkle. Nonetheless, step performs provide a sleek glow and with less light.    

Shards from chipping make the setting tougher, making this type of diamond need more protection with setting them. Some of the most known ones include:     

Prong Setting: Around each corner, a three-prong or V-prong set is placed, allowing the most light while protecting at the same time.     

Bezel Setting: The diamond is enclosed within a sturdy metal rim, giving it a modern touch.     

Side Stone Setting: This diamond is commonly used as a side stone for engagement rings to go with a round, princess, or oval center stone.    

Size Perception and Carat Weight   

Due to the spread-shaped structure, these diamonds look bigger per carat. A one carat round diamond has more than a one carat trilliant diamond, therefore, it is more economical for people wanting a larger looking diamond for lesser costs.

Keep in mind that a trilliants diamond’s inclusions can be more visually pronounced because of the their cut. Therefore, the clarity and color needs to be examined closely. A good value is often found in the VS and SI clarity grades. For setting color, almost colorless diamonds (G-H) are perfectly fine unless they are set with yellow or rose gold where lower color grades are more favorable.

With their unique shape and exceptional capacity to refract light, they guarantee a stunning and one-of-a-kind appeal no matter whether they are set as the center stone or as accent gems.
