Men's diamond cufflinks are the one jewelry item that comes closest to a pair of women's earrings. For men, collecting cufflinks is akin to women collecting earrings.

For almost any occasion there are cuff links in geometric designs, rows of ridges, or a cross-hatch or checkerboard design. Mens' diamond cufflinks are often set in gold with a contrasting gemstone such as ruby, emerald, saphhire, or onyx.

Diamond tie tacs, diamond tie bars, diamond tie tacs, and diamond lapel pins follow much the same route as diamond cufflinks - just as men collect ties that reflect their interests and hobbies, and have a wardrobe of ties for various occasions, there's a variety of diamond tie jewelry available.

And don't forget all the antique cufflinks and tie tacs that are also available.
