Trillion cut, or TRILL, refers to a triangular-faced synthetic quartz gemstone. The trilliant shape is made up of a pointed triangular crown above a kite-shaped base. Its narrow pavilion facets mean precise cutting is vital. TRILL synthetics exhibit remarkable brilliance thanks to their symmetrical, geometric faceting. The triangular faces act like prisms to refract incoming light. This scattering creates colorful flashes known as dispersion or “fire.” TRILL quartz comes in colorless white or vivid hues like bright pink. Often found as accent stones, trilliant quartz adds sparkle and intrigue. The Trilliant cut highlights the flawless clarity of synthetic stones. For light-maximizing appeal, TRILL is an excellent choice.
