This triangular cut is becoming more mainstream thanks to modern uses in new designs
The trilliant or trillion cut is often relegated to side-stone status in settings, but it is becoming more high profile thanks to designers. Trilliants make for unexpected center stones in engagement and fashion rings and chic geometric looks in other styles. According to GIA, trilliant cuts first entered the market in 1978 as a triangular version of the square-shape radiant. Pricescope, meanwhile, notes that the trilliant “comes to three very sharp points, while other triangular brilliants may have softer and slightly rounded points.” Whatever your preference, trilliants are sure to beautify jewels modern and classic.
