Vintage Jonas Koch 14K Two-Tone Gold Modernist Cufflinks, 13.33g

Vintage Modernist cufflinks crafted in marked 14K gold and attributed to New York jeweler Jonas Koch. The asymmetrical geometric faces feature finely crosshatched white-toned panels framed by polished yellow gold, creating a distinctive two-tone mid-century look.

The cufflinks are fitted with traditional swivel backs and have a substantial combined weight of approximately 13.33 grams. Each is stamped “14K” alongside an interlocking “JK” maker’s mark consistent with the documented mark associated with Jonas Koch.

The pair remains in good vintage condition with light scratches, minor spotting or discoloration across the textured surfaces, and normal wear appropriate to age. No major dents or structural damage are visible in the supplied photographs. Please review all images closely for condition and finish details.
