Historically, the origins of the Portuguese Round cut are somewhat enigmatic, with limited definitive records. Its name suggests a possible connection to Brazil or South America, potentially linked to the region’s rich gemstone deposits, such as tourmaline or topaz, which are often cut in this style. Some sources speculate it emerged as a modern innovation, possibly facilitated by the advent of precision cutting tools which allowed for intricate facet arrangements. Unlike earlier cuts like the cabochon or rose cut, which prioritized weight retention, the Portuguese cut reflects a design-driven approach. Its complexity and labor-intensive nature suggest it was crafted to showcase the cutter’s artistry, elevating the gemstone beyond mere adornment to a symbol of technical mastery and innovation.

In terms of popularity, the Portuguese Round cut remains a niche but highly coveted choice in fine jewelry, particularly for those seeking distinctive, high-end pieces. Its intricate faceting makes it ideal for larger stones, where the full effect of its scintillation can be appreciated, and it is often used for colored gemstones like tourmaline, sapphire, or moissanite, as well as lab-grown diamonds. Though one of Missy Reno Smith's favorites, she typically reserves its use for custom designs since each Portuguese Round cut stone must be individually sourced or custom cut.
