Portuguese Cut Lab Grown Diamonds – Maximum Brilliance, Rare Precision
A Portuguese cut diamond is one of the most intricate and brilliant diamond cuts in the world. Unlike traditional round brilliant diamonds with 57–58 facets, the Portuguese cut features up to 161 expertly aligned facets, creating exceptional light dispersion, fire, and visual depth.
Originally inspired by European diamond-cutting techniques, the Portuguese cut is prized for its luxury appearance, rarity, and dramatic sparkle. When crafted using lab grown diamonds, it offers all the brilliance of a high-end mined diamond—without the ethical or environmental impact.
