About this item
This exquisite oval box is a quintessential example of the work of Marius Hammer (1847-1927), one of the most important figures in the history of Norwegian decorative arts. Active in Bergen, Hammer's workshop became internationally famous during the Art Nouveau period for its masterful use of guilloché enamel, a technique where translucent enamel is fired over a machine-engraved, patterned silver base. This piece, dating from circa 1900-1915, showcases the technique at its finest, with a vibrant light blue enamel revealing a shimmering, wave-like pattern beneath. The use of 930 silver, a higher grade than the sterling standard, marks this as a luxury object from the firm's top-tier production. Such items were highly fashionable personal accessories and popular with affluent tourists and European elites. The market for high-quality Scandinavian enamel remains strong, and pieces with a definitive attribution to a master like Marius Hammer are particularly sought after by collectors. The combination of a prestigious maker, superior materials, and iconic Art Nouveau design makes this a significant and highly desirable work of art.
How the value was reached
The valuation is based on the item's confirmed attribution to the highly desirable maker Marius Hammer, its superior 930 silver content, and the high quality of the guilloché enamel work. Direct, recent auction comparables for this specific model were not available, and the provided comparables are for lower-quality, unattributed, or different types of items (e.g., sterling compacts, brooches), which serve only as a market floor (c. $100-$200) and are not suitable anchors. The estimate is therefore based on specialist knowledge of the market for high-end Norwegian enamel, where signed pieces by major makers command a significant premium. A conservative auction estimate would be $800 - $1,200. We would recommend a reserve price of $700. After a typical seller's commission (10-15%), the net proceeds to the seller would likely be between $680 and $1,080.
Expert notes
The valuation rests heavily on the confirmed attribution to Marius Hammer. However, the provided comparable sales data is for items of lesser quality and different makers, making the estimate an expert judgment rather than a data-driven one. Before offering for sale, it is essential to have the box physically examined by a specialist in Scandinavian silver. They should inspect the enamel edges under magnification for any hairline cracks or chips not visible in photos, as this would significantly impact the value.
