This is an exceptional pair of convertible dress-clips and clips-on earrings created in New York by the jewelry house of the Oscar Heyman Brothers. This pair was designed as spiky six-pointed stars in the height of the art-deco period between the 1939 and 1935 and masterfully crafted in solid platinum with polished finish. They are embellished with a great selection of twenty-six white colorless diamonds and a fantastic suite of twelve Siberian purple amethysts. They are fitted with comfortable hinged French omega backs to wear as clips-on earrings and with retractable concealed pins to wear as a dress-clips. This pair is a masterpiece in itself with exceptional quality and precise workmanship.
The Siberian Amethysts
The dark purple deep Russian amethyst is largely considered one of the rarest high-grade amethysts. However, rare does not always equal sought after. The value of the amethyst may depend on the labor needed to facet the semi-precious stone. “Deep Russian,” from Siberia, is the highest grade of amethyst. It is usually very deeply colored. The mines that produce it have been depleted, so it is quite rare, making it the most valuable amethyst. This specimen is at the Gallery of Mineralogy and Geology in the French National Museum of Natural History in Paris. The highest-grade amethyst (called deep Russian) is exceptionally rare. When one is found, its value is dependent on the demand of collectors; however, the highest-grade sapphires or rubies are still orders of magnitude more expensive than amethyst.

The Oscar Heyman & Brothers Company
This is an American jewelry firm and manufacturer that first gained attention in the 1920’s. In 1906, Oscar and Nathan Heyman immigrated to the United States from Latvia. Thanks to an apprenticeship at their great-uncle’s Faberge workshop, they arrived with a skill that made them instantly employable: They could work with platinum, a metal relatively new at the time. Oscar was hired to work in Cartier’s first New York workshop at 712 Fifth Avenue, he was the first non-French bench jeweler hired by the firm. When the whole family moved to New York in 1912, Oscar, Nathan, and Harry Heyman founded the company in the same year. They were later joined by their three younger brothers, George, William, and Louis, along with two sisters, Frances and Lena. In 1970, Oscar Heyman died, and his youngest brother, George, took over the business. The company continued to expand globally during the 1970s while still making products for other high-end jewelry businesses and selling directly to department stores such as Neiman Marcus. Other Heyman family members have continued to run the company over time, with the current president being George's son Adam Heyman. The company's jewelry is still highly regarded and frequently worn by celebrities on the red carpet.
