Hargo Jewellery Company – “HAR” mark was owned by Hargo Creations in New York. The founders were Joseph Heibronner & Edith Levitt in 1955.
Joseph was born in 1893 in Munich, Germany, became a US citizen in 1948 and married Edith Levitt in 1952. Their address at that time was Grove St. in NYC. Joseph died in August of 1968.
The “HAR” mark was probably used from the beginning in 1955 to 1957, or so. Some pieces of HAR jewellery are among the most sought after by collectors and often bring fantastic prices for dealers. Included in this are the dragon, cobra and Chinaman pieces, with full parures, bringing the highest prices.
April 1959: Dragon Design bracelet, earrings, necklace and brooch ( the “Cobra Set” dates from the same year, as do the non figural pieces using the same translucent stones known as “dragon teeth”.)
April 1959: Far Eastern bracelet, necklace, earrings and brooch (probably refers to the “Genie Set” sorceress, turbaned heads, etc.)
May 1960: Chinese face and figure pieces
No more copyrighted designs until September 1967: Insect pin and maybe many other of the cheaper figurals
