Method 1:
- The Hands-on Method
- Grab a tape measure, length of string or strip of paper.
- Wrap it around the finger you'll wear your ring on—if you’re creating a ring stack, consider where on your finger the ring will sit—and mark the place where it joins.
- Lay your string or paper strip on a flat surface and use a ruler to measure the length up to the mark. Use the chart above to match the measurement to the closest ring size.
Method 2:
- Measure an Existing Ring
- Choose a ring that already fits your finger well.
- Measure the interior diameter of the ring in millimeters (mm).
- Use the measurement chart above to match the size of your ring to the closest size in mm.
Complimentary Ring Sizer
Once an order has been placed, we will send you a complimentary ring sizer, which should arrive within 2-5 business days. Once you’ve determined the ring size, simply contact us and we will proceed crafting your ring to perfection.
⏰ Order today to receive your ring approximately by 25th Sep.
PRODUCT DESCRIPTION
Are you interested in designing a beautiful bespoke engagement ring for yourself or your partner? Our Bespoke design service allows you to design your dream ring from the comfort of your own home, with the security of not paying the full ring price until you have a design you are completely happy with. If you choose to go forward with creating your custom engagement ring the price of this service will be deducted from your final amount.
Once you purchase this service we will work on creating your bespoke engagement ring over these 3 simple steps.
- Having an in-depth consultation
Over the phone, through emails and messages we want to know everything. During these consultations you can tell us all about your partner, your relationship, your ring ideas, your budget and you can send us photos of similar rings or any inspiration images. Using this information we can work on conceptualising and creating the perfect ring for you.
- Reviewing a computer generated image
- We make your ring
If you then decide you are happy to go ahead in having your design made into a reality, we will be able to provide a final quote for having your ring made with each of your previously discussed/chosen specifications. After this we will provide an estimated date of completion and a link to pay a deposit. Once this is done our expert goldsmiths will get to work carrying out the production of your dream ring.
