A combination of 60 years of experience in Fancy Shape diamonds and new generation business savvy puts us at the cutting-edge.

Art is what drives Vulcan and Co: the art of cutting and polishing an exquisite, high-end Fancy Shape Diamond; the art of customer service; the art of discretion.
These are our hallmarks, ever since our founder, Ze’ev Vulcan opened Vulcan’s doors in 1952. Our sparkling history and family tradition is rooted to Belgian ancestors who passed down their know-how to a generation settling in Israel – one of the world’s leading diamond centers.

Attracted by the artistry required for creating a perfect Fancy Shape diamond, Ze’ev Vulcan made the fancy side of diamonds his passion. One of the first Israeli manufacturers to specialize in this field, he proved to be a master craftsman with a fine eye for detail. Quickly becoming a cut above the rest, Mr. Vulcan opened several diamond polishing plants staffed by expert artisans, thereby beginning a 60-year legacy of working in fancy shape diamonds. His love for his profession has now been passed down to the third generation.

By joining forces in 2005, Gil and Meni created an unparalleled partnership of vision and skill.

Thanks to Meni’s know-how and expert eye, Vulcan sources and purchases unparalleled stones. A master craftsman, Meni knows how turn each diamond into a unique creation, guiding his expert staff in the cutting, manufacturing, and repairing process.
