Deakin & Francis offer a wide range of cufflinks through Barneys but the Black Sheep Cufflinks are my favorite. Self-described as "the world's finest collection of cufflinks for exclusive supply to retail outlets", Deakin & Francis have a range of offerings including bespoke services. The cufflinks below are fun and playful but the whopping $450 price tag is a little rough on the wallet.
The Earth Cufflinks by Fluid Forms are miniature topographies (of any location) cast in .925 sterling silver. To order, a tutorial first asks for you to choose a location. Then you have the option to pick your zoom level, producing a draft of the topographic map that will become an accessory. Normally I think customization chips at professionalism but the second picture shows that unique cufflinks can still be classy.
