5mm or 6.5mm? How to choose your moissanite stud size

Our moissanite studs come in two sizes. Here's how to pick the right one, for yourself or as a gift.

5mm: everyday sparkle (£35)

A neat, classic size that goes with everything, from the office to the weekend. It suits smaller earlobes, second piercings and anyone who prefers a quieter sparkle. Each stone is the size of a 0.5ct diamond.

6.5mm: a statement stud (£45)

A bolder stone that catches the light from across the room. Great for evenings and special occasions, or for every day if you like your sparkle noticed. Each stone is the size of a 1ct diamond.

How big is that, really?

A UK 1p coin is about 20mm across. A 5mm stud is a quarter of that width, and a 6.5mm stud is about a third.

What does "diamond-equivalent" mean?

Moissanite is slightly lighter than diamond, so jewellers describe its size by the diamond it matches. A 6.5mm round moissanite has the same width as a 1ct round diamond, so it's described as 1ct diamond-equivalent.

Can't decide? Mix both

Buy any two pairs and save £10, and you can mix sizes: 5mm for every day and 6.5mm for nights out. Or keep one pair and give the other.

Every pair is 925 sterling silver with screw backs, arrives gift-boxed, and comes with free tracked UK delivery and 30-day returns on unworn earrings.
