Don't worry if the ring isn’t the perfect fit straight away — your first resize is complimentary to ensure it feels just right. If the ring can’t be resized, we’re happy to exchange it for the correct size within 90 days of purchase. You can visit any ROX boutique where our experts will measure your partner’s finger and arrange the resize in our workshop. Simple adjustments, such as moving a size or two up or down, are usually completed within a few days, and we even offer a same‑day service in Glasgow for urgent requests.
ROX holds a wide range of finger sizes in stock and advise that M is the most popular for women and T for men. If your choice doesn’t fit we can adjust any of our classic styles and we offer the first sizing free of charge.

If you need help finding your ring size, use the our guides below or simply pop into one of our boutiques and we’ll size your finger for you.

At ROX, we hand‑select only the finest precious metals to ensure every piece feels exceptional, lasts beautifully and suits each customer’s personal style.
Platinum and white gold may look similar, but they are two distinct and different metals.
Platinum is our signature luxury metal – rare, naturally white, incredibly durable and perfect for securing diamonds, with a weight and patina that feel unmistakably premium. Platinum retains its colour and develops a beautiful patina over time. If you prefer the the 'as new' appearance of platinum, ROX can polish your ring to look like new again.
Pure gold is naturally yellow so white gold is crafted from pure gold mixed with white metals and finished with a bright rhodium plating, giving it a sleek, mirror‑like shine. White gold offers a bright, modern look thanks to its rhodium‑plated finish, making it a stylish and accessible alternative to platinum with a lighter feel. The mirror like rhodium-plated finish does wear-off over time and your ring might look a little yellow which is normal for white gold. To restore the highly reflective rhodium finish, ROX can re-rhodium plate your ring to look like new again.
Yellow gold brings timeless warmth and elegance, celebrating a classic look that’s firmly back in demand, while rose gold adds a romantic, distinctive blush tone ideal for those seeking something unique. For customers who want versatility or standout design, our two‑tone options blend contrasting metals to create depth and modern appeal. Each metal offers its own character, ensuring every ROX ring reflects the wearer’s taste, lifestyle and story.
All are stunning choices — it simply comes down to the look, feel and level of maintenance you prefer.
Yes, platinum is considered hypoallergenic because it's a naturally pure, dense metal that is less likely to cause skin irritation or allergic reactions compared to other metals, making it excellent for sensitive skin. Its purity means it rarely causes irritation.
White gold is not a naturally occurring material; it is a man-made alloy created by combining yellow gold with other white metals which means it isn't inherently hypoallergenic. White gold is plated with hypoallergenic rhodium creating a barrier that works for sensitive skin but over time the plating wears off and this can cause skin irritation for sensitive skin.
Yellow gold is generally considered hypoallergenic, especially in higher purities (18ct) because pure gold doesn't cause reactions; however, the alloying metals added for durability for lower carat gold (9ct, 14ct) can cause irritation and a higher risk of allergy for sensitive skin. 18ct gold offers a great balance of durability and low allergy risk.
Even if metal for the ring is hypoallergenic, sometimes trapped moisture or chemicals under the band can cause rashes to sensitive skin.
Yes, all our platinum and gold jewellery is hallmarked. Anyone selling precious metal jewellery in the UK — whether a retailer, importer or craftsperson — has a legal responsibility to ensure their pieces are properly hallmarked. A hallmark is a series of official marks applied to a precious‑metal item by one of the UK’s independent, government‑appointed Assay Offices.
There are four Assay Offices in the United Kingdom: Edinburgh, London, Sheffield and Birmingham. Before any hallmark is applied, each item undergoes rigorous testing — known as assaying — to verify its metal purity.
Hallmarking exists to protect you. Because precious‑metal jewellery is typically made from an alloy — a combination of precious and base metals — it’s impossible to determine purity by sight alone. Assaying provides independent confirmation that the metal content matches what is advertised. Consumers have a legal right to this guarantee, and all sellers must ensure that eligible products carry a correct and compliant hallmark.
Yes, you can add a personal touch to your ring with our engraving service. From initials and dates to meaningful short messages, our craftsmen can engrave most engagement ring styles and wedding bands. Choose from classic or script-style engraving to make your piece uniquely yours. Pricing varies depending on the length and detail of your message, so contact us to discuss your specific requirements.
Yes, you can create a ring that’s uniquely yours with our Bespoke Design service. From your first consultation to the final polish, our experts guide you through selecting your diamond, refining your design and approving every detail. Each bespoke piece is handcrafted in our London workshop by master craftspeople using a blend of advanced technology and traditional techniques, ensuring exceptional precision, beauty and individuality. A truly personal experience, tailored to your vision and crafted to last a lifetime.

Yes, every ROX engagement ring is provided with an International Guarantee and Service Plan. The International Guarantee covers the ring against any manufacturing defects for a period of 3-years from the date of purchase. For the guarantee to remain valid, your ring must be checked and serviced by ROX at least once a year.
As part of the Service Plan, we’ll check and professionally refurbish your ring, once a year for the next 3-years so it’s restored to a perfect condition, just how it looked when you first saw it. Simply pop into any of our boutiques to organise a service or book an appointment to visit us. We’ll keep a record of the Service Plan on file.
Please note that the International Guarantee does not cover loss or damage resulting from accidents, mis-handling, abusive use (i.e. knocks, crushing, etc), unauthorised alterations or repairs, stones loosened by impact, rhodium wear, tarnishing and general wear and tear.
You can keep your ring looking its best by following our tips:
Avoid wearing your ring during heavy or abrasive activities, as even durable stones like diamonds can chip if struck hard.
Remove your ring when applying lotions, sunscreen or perfume, as these can dull the diamond’s brilliance and affect porous gemstones, and keep it away from chlorine bleach or harsh household chemicals.
Store each piece separately in a soft pouch to prevent scratching.
Bringing your ring to ROX for a professional clean and check each year helps keep it looking as beautiful as the day you received it. Over time, everyday wear can cause a build‑up of dirt, loosen settings, or create small signs of wear that aren’t always visible to the eye. Our experts will deep‑clean your ring, restore its sparkle, and carefully inspect the claws, stones and metalwork to ensure everything remains secure and in perfect condition. This simple annual visit helps protect your jewellery, maintain its brilliance and give you complete peace of mind for years to come. Some insurance companies make it a requirement so check with your insurer.
Finally, ensure your jewellery is properly insured—most home insurance policies can cover it, though you may also choose a dedicated jewellery policy for extra peace of mind. Contact Us for an insurance quote.
A ring from ROX is designed not only to be beautiful, but to be worn and enjoyed every day. Made with exceptional attention to detail, each ring is built to stand up to the rhythm of daily life while maintaining its brilliance. Superior quality precious metals and expertly set stones ensure long‑lasting durability, while our meticulous craftsmanship provides the strength and security you can rely on. With the right care — and an annual clean and check with ROX — your ring will continue to shine, making every day feel a little more special.
Yes, you can book an appointment to visit one of our boutiques to view and try on the ring. Simply select the reason for your visit, the boutique from our list of locations along with the date and time that best suits you from the available slots.
Provide us with your name and contact information, along with details of the ring you would like to see and submit the form. We will make sure the ring is ready for you to view and transfer it from another location if required. Once the ring is here, we will send you a confirmation via email. We’ll roll out the red carpet for your visit and if for any reason you can't make it, you can reschedule it or cancel at anytime.
