Please help identifying hallmark

[getnautical]

I have a Art Deco Pendant/Brooch piece that reads 14K with an arch above and two circles on the ends of arch.
Does anyone know the hallmark?

Hi Monica,

Welcome to the Forum.

To me that looks like the trade mark of a firm called Day, Clark & Co. of Newark and New York. Hopefully someone will confirm/deny.
