Sphinx is a jewelry company that was based in Cheswick England. Founded in 1948 by S. Root they produced jewelry till the late 1990's. This Sphinx oval logo is from the 1950's. This company also worked for Butler and Wilson, Jay Kenneth Lane and Jomaz. This French inspired pin is obviously older however it is in excellent vintage condition. It has many embedded clear crystals with a colored baguette band. It is 2 1/2" by 1 5/8". We feel this piece has a unisex component.
