While the two patent numbers on these Christian Dior cufflinks date from the 1950s, I believe this cufflink design was not produced until the 1960s or early 1970s. 

The cufflinks are a framed disk button style and the buttons are signed 12kt gold on the backs. The gold cufflink mechanisms are signed 1/20 12kt GF. The design features polished round premium Jade cabs. The Jade has an even, rich marbled look. 

The cufflinks are medium in size at 3/4" wide. The pair is in pristine clean like new condition with no imperfections, flaws, or gold wear. The backs have slight darkened patina to the gold from age.  

Both cufflinks are signed with the Dior and 12kt gold signatures.  Comes gift wrapped in a new luxury presentation cufflink box as pictured.
