August William Holmström was a Finnish goldsmith master born in Helsinki, Finland. In 1850 he became apprentice to the jeweller Herold, and became a master in 1857. In the same year he was appointed chief jeweler by Gustav Fabergé (the father of Karl) a post he held until his death. He is recorded as the maker of the 1892 Diamond Trellis Imperial Egg.
His workshop produced a wide range of precious objects, from exclusive jewellery to miniature Easter eggs. Of the important commissions which his workshop undertook, the miniature replicas of the Russian imperial regalia, exhibited at the Exposition Universelle in Paris in 1900 and now in the State Hermitage Museum, St Petersburg, are perhaps the most famous.
Holmström’s descendants continued his work. His son Albert carried on the workshop. His daughter Fanny Florentina (1869 - 1903) worked with Fabergé, and employed the Finnish gold smith master Knut Oskar Pihl (1860 - 1897). Their daughter Alma Theresia Pihl (1888 - 1976) was active starting from 1911 as decoration designer at the side of her uncle Albert Holmström with Fabergé.
