Choosing the right diamond earring size is easier when you compare each option by how it feels: classic, noticeable, bold, or statement-making.

If You Only Remember Five Things...

Every Size Has Its Own Personality

Think about how each size feels to own, not just the number on paper.

The Classic

Balanced, timeless, and easy to wear often.

Shape Changes How Size Looks

Round is the most familiar reference point, but oval, pear, emerald, and princess shapes can face up differently.

5

Buy the Pair You Will Reach For

The best pair is the one you actually enjoy wearing.

My Recommendation

If you are deciding between two sizes, do not start by asking which one is more impressive. Ask which one feels like you.
