Earring size guide

Our studs come in three sizes. Each size is the weight of the diamond in each ear, so 1.00ct means 1.00ct in each ear.

Round studs

The gold bar shows each size to the same scale.

Princess studs

The gold bar shows each size to the same scale.

Measurements are approximate, as every diamond is cut a little differently. The gold bars above are drawn to the same scale as each other, so you can see how much larger each size is.

1.00ct in each ear

A refined stud that catches the light without drawing attention. A good first pair, and easy to wear every day.

1.50ct in each ear

Noticeably larger, while still sitting neatly on the ear. A popular step up for a gift.

2.00ct in each ear

A statement pair with real presence. Our largest size, for those who want the sparkle to be seen.
