Layering yellow and white gold necklaces together is very on-trend and creates a brilliant contrast between metals. Yellow gold also makes white gold jewellery appear much whiter and enhances its lustre, as well as providing a nice balance between pieces.  You can always start with two necklaces, then continue to build from there. Contrast between different lengths and widths for added depth. You could even add a larger pendant as your centrepiece and surround it with a mix of smaller pendants to create a dazzling display.   White gold diamond necklaces are especially good to use as a base for layering your necklaces. Pair with a beautiful chain to make it stand out, a yellow gold chain will give your diamond a timeless glow. Even other metals like rose gold can make a white gold necklace look classic and clean, while bringing out the warmer tones found in yellow gold.  The great thing about yellow and white gold necklaces is their versatility. Whether you choose to layer them or wear them on their own is entirely up to you. Either way, you’re guaranteed to have a showstopping look.
