Visit our Showrooms
In order to get the most accurate results, the best option is to have your size measured at one of our showrooms in London, Manchester, Berlin or Frankfurt.
Trying on a ring is just like trying on shoes: you need to get the size right. Our team of professional jewellers will have you test a series of different ring sizes to find the most comfortable option for the ring you are looking to purchase.
If you are planning a proposal, we will also offer personalised and professional advice to help you prepare. Book an appointment today.
Measuring your ring size at home
There is much advice online on how to measure your ring size at home. Perhaps you even have heard of methods such as using pieces of string or paper. The reality is these methods are all highly inaccurate and may show completely distorted results, which would be regrettable, especially when planning a surprise proposal.
How do we know this? Simply because we’ve tried and tested them ourselves. At 77 Diamonds, we want to give you the most honest advice so you have less to worry about.
Order a ring sizer
Your best at-home option would be to contact our Customer Services and request a free finger sizer, which we will send by post. (For UK customers only.)
As you will be measuring your finger yourself, there is always a risk of inaccuracy. Follow these steps on how to use our ring sizer:
- Place the ring sizer on the chosen finger and tighten until it sits comfortably. The ring sizer shouldn’t be loose enough to turn on your finger nor too tight that it becomes impossible to move. If you feel a slight pinch, you may want to loosen the sizer a little.
- Check if you can move the ring sizer over your knuckle. There should be a slight pull or struggle when doing so, but you should still be able to remove it without altering the size.
What if I’m planning a surprise gift or proposal?
Ask a close friend or family member
If you are unsure of a person’s ring size, it’s always best to discreetly inquire around you. Close friends or family members may be able to help, or at least give you a good indication of your partner’s ring size.
Measure a ring he or she already owns
It’s important you use a ring usually worn on the finger you are seeking to measure, especially if you are looking for an engagement ring. You’ll get the most accurate size if you take it to our showroom to be measured without them noticing.
However, if you are worried your partner may notice a missing ring, you can also try to measure it at home by using our printable ring size cutout and following the instructions above. Keep in mind any manual method to determine ring size may result in inaccuracies.
What if I order the wrong ring size?
Making a mistake in your ring size isn’t the end of the world. At 77 Diamonds, we offer a free resizing service for up to 30 days after receiving the item.
Our expert craftsmen will take care in returning your ring both cleaned and polished, ready to fit on your finger.
Keep in mind a certain number of our rings cannot be resized. These include full set diamond eternity rings, milgrain or ornate bands as well as certain bespoke or personalised rings.
If you have bought a ring which cannot be resized, we can exchange your purchase for another ring of similar style within 30 days of receiving the ring. Should you choose a new ring containing more gemstones or diamonds, you may be required to meet the price difference.
