If you are still not sure about your ring size we can send you a free sizer. Just email us or fill in the form below. They’re easy to use and come with full instructions so you can order with confidence. We can also send you a sizer out in the post before you order.

Before measuring the finger on which you will wear your custom-made ring, please ensure the following: 1. Do not measure a finger when it is cold or too hot as this can have a significant effect on a ring size. For example, when your fingers are cold they can be at least half a size smaller. 2. For an accurate reading, measure your finger at the end of the day, when it is larger.

Your ring should fit your finger comfortably. It should be snug enough so that it won’t fall off, but loose enough to slide over your knuckle. Do not forget that there are significant differences between the right and left hand. It’s also worth bearing in mind that rings with a particularly thick band will feel tighter than a thin band; in these cases, we recommend buying a full size larger than your normal ring size. Please make sure you order the correct size.

If you are hesitating between two sizes, we tend to recommend that you choose the larger.

If you are buying the ring as a gift, ask a close friend or family member if they know the correct size or have a ring that fits perfectly that can be measured.

Product Care

When you love something, you don.59;t throw it away or replace it. You mend it. We can lovingly renew and restore sterling silver and gold vermeil jewellery - just like my grandparent.59;s mended my clothes for me when I was a child.

Renewing scratches and minor damage: Small scratches, broken posts, missing stones - these can also be easily repaired - so they can last a life time and become heirlooms.

Renewing: Completedworks gold vermeil plating is 2.5 microns thick - which means the gold will last 2-3 years of regular wear. If it does become worn, we can offer an affordable and hassle-free replating service.

We use recycled metals from refiners committed to sustainable practices, melting down existing silver and gold to create high-quality materials with a lower environmental impact. Our recycled glass is made from scrap windows and bottles.

* Made in 18ct yellow gold

* Ethically sourced materials

* One year guarantee

* It is certified in accordance with the Hallmarking Act 1973
