Sidersky & Son, with more than 100 years of continued trading, was the oldest family-run jewelry manufacturing company in South Africa from 1902-2006. Adolph Sidersky, the founder, was educated and trained in Leipzig, Germany, as an engraver, setter and jeweler. He emigrated to South Africa in the late 1800s, participating in the Boer War. After the war in 1902, he opened his own manufacturing jewelry studio in Johannesburg. In 1928, his son Max joined the business, taking over the company when his father died in 1959. The studio specialized in the mounting and setting of gemstones in platinum or gold, gaining a reputation for excellence in their craftsmanship – indeed commissions in the early 1950s included those from a South Rhodesian firm for jewelry that was presented to the young Princess Elizabeth, and later to the Queen Mother and Princess Margaret. In the late 1950s, Max Sidersky was active as the chairman of the South African Manufacturing Jewellers Association, with a progressive attitude to the development of jewelry manufacturing and hallmark standardizing. The company was sold in 2006.
