C.J Co. stands for China Jewelry Co., a gold, silver and jewelry store in Shanghai, China during 1920s~1930s (probably located at Nanjing Road, I need to check). I have seen marks CJ, C.J., C.J. Co for this company/store, and even 'CHINA JWLR' mark on a CES silver bowl onces. I also seen some items have both C.J. Co and NK (Nankin Store in Shanghai) marks.
