About this ring

While our prices may appear lower than most jewellers, the quality behind each piece speaks otherwise. In fact, our production costs are often higher — because we insist on doing things the right way:

  • Every piece undergoes multiple rounds of quality control
  • We use thicker bands, meaning more gold and longer-lasting wear
  • Only top-grade gemstones make the cut for our collection

By keeping our margins low and prioritising craftsmanship over markups, we’re able to offer exceptional jewellery — at a price that’s genuinely fair.

We provide an IGI jewellery report for designs set with three or more gemstones and a total carat weight of 2 carats or above.

While most UK jewellery brands only provide IGI certificates for lab-grown diamonds, we ensure that the lab-grown gemstones we use are also accompanied by a dedicated IGI report.  So you’ll always have peace of mind that every stone originates from a place we’ve personally chosen for its ethical practices.

You can learn more in our Gemstone & Jewellery Certification Guide.

Frequently asked questions

  • Yes — most of our wedding bands are made to order and crafted just for you, with a typical lead time of 6–8 weeks. If you need your ring by a specific date, feel free to reach out and we’ll do our best to accommodate.

  • We offer a curated selection of wedding bands that complement our engagement rings in both shape and design. While not every style has a direct “set,” our team can help you find a band that harmonises beautifully.

    You can discover our full selection of Bridal Sets, thoughtfully paired to celebrate your perfect match.

  • Traditionally, an engagement ring or a wedding ring is worn on the fourth finger of the left hand, often referred to as the "ring finger." This custom dates back to the ancient belief that a vein in this finger—the "vena amoris" or vein of love — ran directly to the heart.

    Of course, traditions can vary by culture and personal preference. Some people choose to wear it on their right hand, especially in different parts of Europe or for practical reasons. There’s no wrong choice — it’s about what feels right for you.

  • If you're unsure about your ring size, we recommend starting with our Ring Size Guide — a helpful resource covering sizing tips, measurement methods, and resizing information. It’s designed to give you confidence when choosing the perfect fit, whether you're buying for yourself or as a gift.

  • We offer one complimentary resizing within 90 days of collection or delivery for all eligible Keanis rings. We understand that sizing can be tricky — especially if it’s for a surprise proposal — so you're welcome to visit us after the big moment for a professional fit and adjustment.

    Please note that resizing is only available for rings made in 18K gold or platinum and typically within three full sizes up or down. Some styles, such as full eternity bands or open bands cannot be resized due to their design. If a ring is non-resizable, we’ll clearly note this on the product page.

  • Yes — all Keanis jewellery is covered by our Aftersales service, which includes complimentary lifetime cleaning and inspections, as well as one free resizing within 90 days of collection or delivery.

    Please note that certain styles — such as full eternity bands or open designs — cannot be resized. Our team will gladly advise based on your specific piece. For more information, visit our FAQs page on resizing and aftersales care.
