History of Triangle and Trilliant Cut Diamonds

5th February 2024 By Coby Shalev

The triangle and trilliant cut diamonds are both unique and distinctive diamond shapes, each with its own history and characteristics.

  1. Trilliant Cut Diamonds:

    • The trilliant cut, also known as the trillion or triangular cut, was introduced in the early 20th century. Its development is often attributed to the Asscher brothers in Amsterdam, who patented the cut in 1962.
    • The trilliant cut is a triangular shape with pointed corners, and it usually has 50 or 58 facets. The number of facets can vary depending on the specific design and the preferences of the cutter.
    • Trilliant diamonds are often used as side stones or accents in jewellery, complementing a central stone, such as a round or princess-cut diamond.
    • This cut is known for its brilliance and fire, as the facets are strategically arranged to maximize the reflection of light.

  2. Triangle Cut Diamonds:

    • The triangle cut, as a general term, can refer to diamonds that are shaped like triangles. However, there is no specific historical timeline for the triangle cut, as it is more of a generic description for diamonds with a triangular shape.
    • Some triangle-shaped diamonds may be step-cut, while others may be brilliant-cut. The choice of cut depends on the preferences of the jeweller and the desired appearance of the diamond.
    • The popularity of triangle-shaped diamonds has varied over time, but they are often chosen for their unique and modern look.

Both trilliant and triangle cut diamonds have gained popularity in contemporary jewellery design, offering a modern and distinctive alternative to traditional diamond shapes like round or princess cuts. These cuts are often used in engagement rings, earrings, and other jewellry pieces to add a touch of uniqueness and individuality to the design.
