Ring Size Image.jpg

We make all our rings to order to ensure you get the perfect fit, so the first thing we ask you for is your ring size as not much can happen without it. It's also the kind of info you should share with your boyfriend or best friend just in case a certain proposal might be on the horizon!!

But getting the size right can be daunting experience, though it doesn't need to be. Follow our ring size guide and helpful tips and tricks to find your size. 


The best time of day to measure your ring is in the evenings when your fingers are at their largest. 

Avoid measuring your fingers when they are cold, as they can shrink up to half a size in the cold. 

Consider the width of the band, the thicker the band the tighter the fight, so you may want to buy a full size larger than your normal ring size. 

Your ring should be loose enough to slide over your knuckle, but not so loose it will fall off.
