Founded in 1948 in the UK, they produced jewellery for such brands as Ciner, Jomaz, and Boucher in 50s and 60s and became known as a manufacturer of high quality costume jewellery. With growing popularity and recognition of their artistic design, the company's client base spread to best brands like Kenneth Jay Lane, Butler & Wilson and Saks 5th Ave.
Marked and numbered Sphinx pieces only appeared in the 1960s and the company ceased operations in the late 1990s.
