Cellini mark

I have a wonderful bracelet that I purchased in a Brussels antique
store that is marked “Cellini”. It is made up of large cast silver
hippo or tiger heads with ruby eyes, interspersed with agate slices,
all set in 18k gold. I have been unable to find any listing for a
company with this name; the only thing that comes up is Benenuto
Cellini. Does anyone have any on
this mark or know where I could go to find out more about it?
