A side stone setting engagement ring is the right choice when anyone who wants more visual interest than a solitaire offers without going as wide as a three stone. It is one of the most considered decisions in the design. The setting changes how the centre stone reads more than almost any other variable.

Why a side stone setting

A side stone setting flanks the centre diamond with one or more smaller accent diamonds on either side. It sits between a clean solitaire and a fully-fledged three-stone. Extra sparkle without overcomplicating the design. Anyone who wants more visual interest than a solitaire offers without going as wide as a three stone.

What to consider

Side stone shapes should complement the centre. Round side stones with a round centre, baguettes with an emerald cut, and so on.

Side Stone Setting engagement rings by shape

The side stone setting works with every diamond shape. Browse by round, oval, emerald, or pear. Every shape is available in both natural and lab-grown diamond.

Every centre stone above 0.30 ct is GIA-certified, Kimberley Process compliant, and traceable back to the mine of origin.
