The simplest way to style your jewellery and ensure you always look pulled-together, is to start with a base piece and then match its material and/or colour in the rest of your pieces.
A common place to start is with your wristwatch. Chances are you have a classic piece that you wear everyday, so you should match the rest of your jewellery and accessories to this. For instance, if you wear a watch with gold as its main colour (or feature colour, if you wear a leather or ceramic watch), pair it with a gold ring or gold chain. If your watch is leather and you prefer to carry the leather through the rest of your look, try a matching leather bracelet on the same wrist as your watch.
Another common piece of jewellery for men is their wedding ring. If you’re married, it’s a no-brainer to use your wedding band as the starting point for your jewellery look. You can easily find pieces of jewellery to match popular men’s wedding ring styles; for example, pair a yellow gold or white gold ring with a matching gold chain, or a watch with accents in the same colour; and pair a tungsten ring with a grey ceramic watch, a leather bracelet with sterling silver accents, or a sterling silver chain.
A black titanium ring is highly versatile, and you could pair this with a black ceramic or leather watch, a black leather bracelet, or, if your ring includes gold accents, other jewellery in the same gold.
