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

  • 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.

Anatomy of an Astley Clarke Bracelet

From colourful gemstones to silken cord and intricate diamond pavé, all of the Astley Clarke bracelet collections are designed with our signature style of relaxed luxury in mind.

We prefer our jewellery to sit loosely around the wrist and are of the humble opinion that when it comes to exquisite jewellery, more is definitely more and one should never be afraid to layer.
