A trilliant shaped gemstone, also known as a trillion or triangle cut, is a triangular-shaped cut with curved or straight sides and pointed corners. The cut typically has 31 or 50 facets, depending on whether it has a step-cut or brilliant-cut. Trilliant-shaped gemstones are often used as accent stones in jewelry, particularly in three-stone rings and earrings. They can also be used as a center stone, particularly in engagement rings with modern, geometric designs.
