Swedish jeweler Gustav Dahlgren
The history of G. Dahlgren & Co, one of the oldest Swedish companies for the production of gold and silver products, spans more than a century. According to Ernst Fischer’s publication on the history of silver and gold production in Sweden, the company began operations in 1845. Gustav Dahlgren, in partnership with the Gold Goods Share Company, founded Guldvaruaktiebolaget G Dahlgren & Co in 1845, merging the two workshops located in the Oxie area in the southeast of Malmö Municipality, Sweden. Later, a branch of Dahlgren & Co also appeared in Stockholm.

Born in 1815, Gustav Dahlgren was a successful businessman, jeweler and philanthropist. He died in 1875 due to a serious illness. In fact, he did not have a family and children who could be the direct heirs of his business. However, his siblings continued the activities of the company, which went through ups and downs, a change in ownership and, accordingly, a change in product labeling.
So, early jewelry marking included “G A Dahlgren”, then “GD&CO” (Gustav Dahlgren & Co). Noteworthy, Swedish silver and gold products have special markings that include several symbols. G A Dahlgren marking, in particular, included M (city mark for Malmö), 3 crowns (Sweden), S mark (in hexagon indicating 830 silver or higher), and some numbers indicating the year of manufacture. For example, “D9” (for 1954), E9 (1955), V9 (1971), etc.

New York jewelry designer Herbert Rosenthal
Founded in 1945, Herbert Rosenthal Jewelry Corporation originally manufactured decorations for Christmas trees. In 1962 the corporation registered two jewelry trademarks – “HR” and “Accent On Value” (1962-1984). Active for twenty-five years, HR jewelry trademark ceased to exist in 1987. Traditionally, the company produced finger rings, bracelets, brooches and pins with the use of 18 K gold, silver and precious stones.
Rosenthal mostly specialized in brooches and his business was successful. By the mid 1960’s he created an iconic design of bejeweled bees that brought him fame. The popularity of insect brooches put Rosenthal at the forefront of the fashion, and also caused some problems for the designer. As many other jewelers began creating similar insect designs, Rosenthal repeatedly sued other companies to protect his copyrights in courts.
Rosenthal’s copyrighted style included golden wings, a diamond-studded chest, and vibrant ruby eyes. The decision of the courts was ambiguous – on the one hand, they agreed that the companies were violating his author’s design, but on the other hand, they ruled that his trademark was invalid. Despite the court decision, he remained the exclusive designer of bee brooches, which became even more expensive. Noteworthy, Rosenthal has created several insect designs for Tiffany & Company.

Flower brooch. Amber, brass, enamel. 5 cm. 1980s. Kuji Amber jewelry

Japanese Vintage – Kuji Amber jewelry
Traditionally, we associate amber with the Baltic Sea. However, Japanese amber is at least twice as old as Baltic amber. Found in Japan, these semi-precious stones are about 80 million years old. The seaside city of Kuji, located in the northwest of the island of Honshu, is called the Japanese capital of amber. The color shades of Japanese amber are quite varied and differ from the Baltic amber. Yellow and transparent stones are quite rare. More often, amber has orange, dark yellow and brown shades, and even beautiful striped amber that looks like agate. Interestingly, in the Middle Ages in Japan, red amber was especially highly valued, which symbolized the blood of the dragon. Only members of the imperial family could wear jewelry made of red amber.
There are many awarded notable artists and jewelry designers who work with amber. In particular, Wataru Zama, Hiromi Ito, Takenori Moriyama, Yuji Okado, Osamu Omori, Masaaki Sakaguchi, Yasunori Sakamoto, Nobuko Takagi, Misao Uchida, Noriko Hasegawa, and Koichi Yamazaki.
In the past, in this area there were several old schools of amber processing, which were famous throughout Japan. Since 1981, the Kuji Amber Museum Co., Ltd. has been reviving the historical traditions of Kuji-kohaku by decree of the Japanese government. The owner of the museum is a local company Kuji Kohaku. Kuji products – earrings, pendants, brooches, bracelets, watches and pens with amber inserts can be purchased both throughout the country and at the place of production.
Noteworthy, items marked with the word “KUJI” are rare, as Kuji Amber Museum only marked the first jewelry collections.

Gray Kingsburg vintage costume jewelry
New York-based jewelry designer Gray Kingsburg worked between WWI and WWII, including the Great Depression, 1920-40. Accordingly, the style of his jewelry has undergone many changes in a short period. At the beginning of his career, these were decorations in the Art Deco and Art Nouveau styles, with the use of natural stones and gold plating. Already in the 1930s, due to a downturn in the economy and limited use of precious metals, the designer used brass, copper and alloys of gold and silver tones to compensate for the shortage of gold and silver. Also, the designer used multi-colored art glass imitating precious stones. A distinctive feature of his designs is exquisite filigree handwork, embodied in bracelets, brooches, necklaces, buckles, and dress clips.
Gray Kingsburg, like many other jewelers of the period, drew inspiration from exhibits in various museums and vaults around the world, creating a line of jewelry with Buddhist and Indian motives. Kingsburg’s exquisite filigree jewelry is a collectible rarity in the vintage jewelry market.
