Launched in 2008 by Australian graduate gemologist Katherine Jetter, the eponymous brand is celebrated for its vibrant, gemstone-focused couture jewelry. Jetter, who trained at the Gemological Institute of America (GIA), is widely credited with reintroducing the Australian opal to the luxury market, a mission rooted in her national heritage. Her designs are led by the stones themselves, resulting in one-of-a-kind creations that feature impeccable color and timeless settings. The brand’s collections, such as the architectural Origami line, showcase rare materials like mint green tourmaline, tanzanites, and pink rhodium, crafted for a discerning clientele of “bold and brilliant women.”
