Small ram's head hallmark

I have a white gold? bracelet with intricate repousse-like details in white gold and the small hallmark is a ram's head. It can't be silver because it never tarnishes and it's very heavy and solid... do you have any idea of the origin of this lovely piece? I know that my grandmother spent her first married years in Versailles in France in and around 1923 after WWI and it could be an antique.
