Another non-traditional cut, the trillion cut diamond is eye-catching and bold in its equilateral triangle shape, and brings to mind a feeling of enchantment or magic. It is one of the more modern diamond shapes, designed in 1962 by Leon Finker.
The trillion cut can have variations such as rounded corners or slightly curved sides. They are often used as accent stones around a center diamond, but can also stand alone as a solitaire for a unique and bold look.
