GEORG JENSEN HALLMARKS
Curious as to how we determine the dates on many of our pieces?
We are fortunate enough to have obtained a handful of old catalogs and internal documents pertaining to the hallmarksused by the Georg Jensen Silversmithy. The different hallmarks have been used during different period of time, and combined with our knowledge of silver content and the years of which the designers were active all combines to help us determine the age of an item. Some of the documents we have included to the side and below.
Under the Danish Hallmarking Act of 1893, the content standard for all silver was set at 826 parts out of 1,000, which is slightly lower than the standard for sterling which is 925. The remainder is usually copper with very small amounts of iron, lead and traces of other metals. The Danish mark, 826S was used until about 1915 when silversmiths raised their silver content to 830 and eventually to 925. Georg Jensen did not switch to the sterling standard until 1927 although he occasionally made special orders in 925S for the American market much earlier. Until 1961, Danish silver was identified by a stamp with three towers. After that an 830S or 925S imprint was used. (A mark with two towers means silverplate.)
Other hallmarks can also include Swedish year markings and The Designer Initials which can further assist in dating a particular item.
A final word must be said. Not all items with a Georg Jensen hallmark may in fact be original pieces. In some cases, some items on the resale market are an amalgamation of Georg Jensen items and either original silver work, or the silver work of other companies. In other, cases, items may be original, but otherwise modified via the addition of stones or other accents. It is best to use an older catalog to assist in verifying the authenticity of the pieces you are interested in outside of jensensilver.com.

Examples of Georg Jensen Hallmarks
Also of note are some of the older clasps, as shown on the left. The clasps have varied throughout the years with their designs each with their own aesthetic and functional aspects. The one pictured is unique in how much attention to detail has been given.
Notice that the hinge connection is actually formed in brass, not sterling silver. The rationale behind this is that as this particular section of the clasp is most prone to force and damage, the brass is actually better equipped to handle the stresses and the possibility of being deformed than the softer sterling silver alloy.
The whole of this clasp formed by hand, and the attention to detail can be seen in the well fitted sliding holding pin, as well as the elegant cut out curves on the structure holding the clasp. The holding pin itself is tube like in it's design, showing consideration for the wearer in its design, as it covers the sharp tip, preventing the wearer from accidentally being poked.
In contrast to one of the clasps above, which uses a simple eye hook, there are many things that make these older clasps unique, and this is yet another way that hints at the ages of our items.
Below are examples of when year marks were used from time to time to mark specifically the year of manufactury of a particular piece..
Designer Initials and Marks
Designer's name, initials, or personal mark have also been added. These were more often used to recognize a designer who was quite influential and notable for the time. For a chart to determine the designer, click HERE
