At Alex Monroe, all of our rings are made by hand in our London workshop. This means that we can make your ring specially to your exact ring size.

When measuring your ring size there are a few things to be aware of:

•  Firstly, your fingers will change size slightly throughout the day. Physical activity, and temperature all have an effect.

•  You shouldn't measure your ring size whilst your hands are cold, as your fingers can be up to half a size smaller at this time.

•  A ring with a wider band will feel a little tighter than a very fine ring. Therefore we would always recommend buying a size larger than your usual ring size.

•  Your ring should fit comfortably, feeling snug enough when you wear it that it won't fall off, but still be able to fit over your knuckle when you take it off.

If you are unsure of your ring size, then by far the best and most accurate way to find out, is to pay a visit to a local jewellers. You can also give us a call on +44(0)2073786061 and speak with a member of our customer service team for additional advice. 

Ordering a special ring size 

If you would like to order a ring size that isn't listed on our website, please give us a call at +442073786061 or message us. We will then be able to confirm whether we can make the ring in your requested size.

Once we have confirmed this, you can place your ring order through our website, selecting the closest listed size.

When placing your order, please make sure to leave a comment with your correct ring size during the checkout process.

Rings made in a size outside of our standard size range will be non-exchangeable or refundable, as we will need to make these specially. We can resize any ring, but there may be a small charge involved to do so.
