Georg Jensen — Jewelry Identification Guide

Georg Jensen founded his eponymous silversmithing workshop in Copenhagen in 1904, quickly gaining international acclaim for blending Scandinavian design principles with Art Nouveau and later modernist aesthetics. The brand became Denmark's most celebrated silver house, producing everything from jewelry and hollowware to flatware and decorative objects. Jensen's legacy of organic, sculptural forms and exceptional craftsmanship endures as a benchmark in silver design.

Georg Jensen pieces are marked with the company name 'GEORG JENSEN' in block capitals and a three-digit design number that identifies the specific pattern. The hallmark also includes a small dotted oval or circle containing the letters 'GJ' or the full name, along with 'DENMARK' or '925 S' to indicate sterling silver and Danish origin.

Older pieces from the early to mid-20th century may carry additional marks including the initials of the individual silversmith who crafted the piece, import hallmarks from countries like the UK (where Jensen pieces were widely sold), and older Danish assay marks. The design numbers are catalogued in reference books, making it possible to date and identify specific Jensen pieces with considerable accuracy.

Look for the 'GEORG JENSEN' stamp in clean block lettering accompanied by '925 S' and 'DENMARK.' The design number is essential for identification and should match known catalogue entries. The GJ hallmark in a dotted oval is a reliable indicator of authenticity, and its specific shape has evolved over the decades, which helps with dating.

Jensen pieces are known for their substantial weight and smooth, hand-finished surfaces. Sterling silver items should feel heavy for their size and show evidence of careful hand finishing rather than mass-production casting marks. Older pieces may have a soft, warm patina. Be wary of pieces missing the design number or bearing a 'GEORG JENSEN' stamp in a font inconsistent with the known marks for the claimed period.
