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.

C1980 18K Signet Ring of Tourmaline w/ Intaglio Carving of Mythical Goat
By Vasari
Located in Baltimore, MD
Substantial signet ring of tourmaline, with a delicately carved and pristine intaglio of a 2 horned goat mounted to a gorgeous gold band. The goat has important significance first in the Bible, representing sacrifice, protection, and guidance. A modern twist on the image of the goat is the acronym "greatest of all time", commonly referred to as the GOAT. The goat is also the symbol for Capricorn, the sign for everyone with birthdays between Dec 22 and Jan 19. The intaglio is so detailed that even the texture of the animal’s fur can be seen and felt when you run your hand across the face of the stone. The goat has a pair of horns, ears and even leg joints that are meticulously carved. The gold band is actually two gold bands circling the stone and forming a continuous double band throughout the ring. The band continues in in a circular pattern around the side mounted tourmalines to the back of the ring, with the repeating circular motifs establishing a strong design element. In addition to the tourmaline central stone, there are 2 cabochon cut tourmalines mounted to each side. The ring is open in the back and the goat intaglio is easily seen both from the front of the ring and back. The ring reads like an early 18th century ring but is in fact a modern ring with stamped Vasari. Vasari was a Catalan...
