A Trilliant cut, also known as a trillion cut, is a diamond shape characterised by its triangle-like outline. This cut is typically symmetrical, with three sides and sharp, pointed corners. The sides of the Trilliant cut may be straight or, in some cases, slightly curved, giving the shape a more rounded appearance depending on the specific design.
This diamond shape is distinctive for its triangular form, and it can be cut in varying styles, from classic triangles with straight edges to more softened versions where the sides are slightly curved. While the Trilliant cut can be used for both round and square diamonds, it is most commonly associated with fancy shape diamonds, offering a modern alternative to traditional shapes like the round brilliant or the pear cut.
Trilliant Cut Characteristics
Shape:
The Trilliant cut has a triangular shape with sharp corners. The edges can be either straight or slightly curved, depending on the design. The curved edges are sometimes referred to as the “modified” Trilliant cut, offering a softer, more rounded appearance.
Facets:
Typically, a Trilliant cut diamond features fewer facets than more intricate cuts like the round brilliant, but it often includes kite-shaped facets on the crown and pavilion. The number of facets can vary, but most Trilliant cuts have around 41 facets in total. The way the facets are arranged plays a significant role in the diamond’s brilliance and sparkle.
Symmetry and Proportions:
Like other diamond cuts, the symmetry of the Trilliant cut is important for ensuring it achieves the best possible brilliance and sparkle. The proportions, including the depth, table size, and crown angle, are critical to its performance in light reflection and dispersion.
Versatility:
The Trilliant cut is highly versatile and can be used for both solitaires and accent stones in a variety of jewellery pieces, including engagement rings, earrings, necklaces, and bracelets. It can be a striking centrepiece or serve as a complementary stone alongside other diamond shapes, adding a bold and contemporary touch.
Variations:
The traditional Trilliant cut is a right-angle triangle, with equal sides. However, variations include elongated Trilliant diamonds, which have more rectangular-like proportions, and curved-edge Trilliant diamonds, which offer a softer and more organic look.
Appeal and Advantages of the Trilliant Cut
Unique Appearance:
One of the primary draws of the Trilliant cut is its distinctive and contemporary look. The clean lines and sharp angles create a bold, dramatic effect that stands out compared to more traditional diamond shapes.
Brilliance and Fire:
The brilliance of a Trilliant cut diamond depends heavily on its proportions and the quality of the cut. Although it has fewer facets than the round brilliant cut, a well-proportioned Trilliant diamond can still exhibit significant brilliance and fire, with flashes of colour and light as the diamond is moved.
Versatile Settings:
Trilliant diamonds can be set in a variety of metal settings, including platinum, white gold, yellow gold, or rose gold, which allow the unique shape to shine in any type of design. Their triangular shape pairs well with both modern and vintage-inspired jewellery settings.
Good Use of Size:
Due to the nature of the Trilliant cut, this shape can help maximise the visual size of smaller diamonds. Because the shape is relatively compact compared to some other fancy cuts, it gives the appearance of a larger diamond while maintaining a well-balanced appearance.
Ideal Uses for Trilliant Cut Diamonds
Engagement Rings:
While the round brilliant cut remains the most popular choice for engagement rings, the Trilliant cut offers a unique alternative for those looking for something different. It can be used as a centre stone or as accent stones around a larger central diamond to create a dramatic effect.
Accent Stones:
The Trilliant cut is often used as an accent stone in designs, particularly alongside round diamonds or emerald cuts. The triangular shape can provide contrast and create a striking focal point in jewellery pieces such as rings, earrings, and pendants.
Modern Jewellery Designs:
Its angular, contemporary look makes the Trilliant cut particularly suited for modern and bold jewellery designs. Whether paired with white diamonds, coloured gemstones, or used alone, the Trilliant cut adds a striking and edgy element to any piece.
Considerations and Drawbacks
Visibility of Inclusions:
Like many fancy cuts, the Trilliant cut’s open design can sometimes make inclusions more visible than they would be in other cuts. This is particularly true for diamonds with lower clarity grades, so it’s important to choose a high-quality diamond for this cut to ensure it is eye-clean.
Size Perception:
While the Trilliant cut is often used for its distinctive appearance, its compact shape may make a diamond appear smaller than a similarly carat-weighted round diamond. For those prioritising size, it is essential to consider the proportions and angles of the cut.
The Trilliant cut is a bold and eye-catching diamond shape that offers a unique alternative to traditional round diamonds. With its triangular form and sharp corners, this cut is ideal for those looking for a contemporary, statement-making diamond. Whether used as a central stone or as part of a design with accent diamonds, the Trilliant cut can add brilliance, fire, and a touch of modern elegance to any jewellery piece.
