Black Cufflinks
When people get dressed up, the first thought is can/should I wear black. Yes, it is a slimming color so many of us like to wear black to look skinny. Also, events are "Black Tie", meaning formal, and not "white tie". I personally like to dress in black because it really matches everything well.
Without a doubt, the most popular black cufflinks design would have to include genuine onyx. A naturally occurring element, black onyx is sought after for men's accessories as it is the most rich, and formal of materials. A classic set of onyx cufflinks and studs is a true benchmark from which all other designs are compared.
