Caroline's Jewelry with a Past is offering a gold vermeil over sterling silver enamel brooch by Finn Jensen, Oslo, Norway c. 1965. This charming modernistic ribbon brooch is done in white guilloche enamel with meticulous engine turning on the silver. A mid century Scandinavian design, it is a perfect example of Finn Jensen's work. The piece measures 2-1/8" long X 1-1/4" wide (maximum dimensions). It has a C-clasp. The brooch is marked "Norway" + "Sterling" + "925S" + "V" (maker's mark triangular shape). It weighs 10.9 grams.
Engine turning is a geometric pattern inscribed onto metal. When applied under transparent enamel, the intricacy of the metal becomes part of the design. This technique is called "guilloche" or "guilloche enamel".
Finn Jensen originally originally worked for J. Tostrup, an early and well known Norwegian jewelry. Finn Jensen and Jnut Aamodt founded a jewelry manufacturing firm in 1946, Jensen and Aamodt. He began his own company around 1953 and primarily manufactured vermeil guilloche enamel jewelry. The company continued in business until Finn Jensen's death in 1976 when it was bought by OPRO, a Norwegian enamel ware firm. The logo was changed in 1976.
The silver content of this piece has been tested using standard accepted testing methods, such as acid testing. The silver is marked "Sterling" and "925S".
