Buying a gift ?

When buying a ring as a gift, the best way (but not always the easiest) is to borrow an existing ring from the correct finger and use our downloadable Ring Size Guide to determine its size.

Tips & Tricks


Measure your ring size at the end of the day when fingers are at their largest. Consider the width of the band, a particularly thick band will feel tighter than a thin band so you may want to buy a full size larger than your normal ring size. Ensure that your ring sizer fits comfortably, snug enough so that so that it will not fall off, but loose enough to slide over your knuckle.

Do Not

Measure your hands when they are cold, they may have shrunk up to half a size. Alcohol and salt can make your fingers swell so refrain from measuring your ring size after any champagne and canapé filled evenings.
