Colleen B. Rosenblat Three-Stone Rings
Colleen B. Rosenblat believes that “it is not we who select the jewelry, but the jewelry that selects us.” Based in Hamburg, Germany, she is known for her contemporary pieces that feature unconventional color and form along with fine materials like pearls, precious gemstones and gold and silver.
When she was a child, Rosenblat stumbled across some smoky quartz in the forest. It ignited a passion for gemology and jewelry that took her around the world. As a teenager, she used a handful of jewelry-making tools borrowed from a friend to craft her own pieces out of silver.
Trips to Australian and Indonesian gemstone mines solidified her focus, and Rosenblat applied to study at the Gemology Institute of America in Los Angeles. After graduation, she studied in Idar-Oberstein in Germany, finished a goldsmith apprenticeship in Frankfurt and earned a jewelry design diploma from Parsons School of Design in New York. She then split her time between the United States and Germany, working as a freelance goldsmith for several years before opening her own workshop and award-winning showroom in Hamburg.
Designed by American architect and interior designer Michael Gabellini, Rosenblat’s showroom luxuriously presents her jewelry. Handmade furniture by American woodworker George Nakashima complements the interior. In 2000, the American Institute of Architects in Philadelphia awarded it the Institute Honor Award for Interior Architecture.
Rosenblat continues to produce exquisite jewelry under her brand. Her work has been featured in high-end fashion magazines such as Vogue, Elle, Harper’s Bazaar, Vanity Fair, InStyle and GQ.
