An engagement ring and wedding band shouldn’t compete with each other—they should be partners. With a set you’ll know the proportions between the two is right and you won’t have to think too hard about it.

Professional jewelers know which styles work together and which ones don’t. Even if you want a custom design to mix and match your favorite trends, a set will ensure you still end up with rings that are unique in the best way possible.

If you choose different strength metals, it’s possible that one ring could damage the other when they’re worn together. For example, platinum can scratch white gold. Buying a set will ensure your rings are the exact same metal.

Buying a wedding band separately could prove difficult if you have to work around certain diamond shapes such as a marquise or a pear shape. A set will ensure your rings are created specifically to be worn together.
