9ct Yellow Gold Blue John Hallmark Large Rhombus Ring. R608_FH.

As anyone with a love of fine jewellery and its craftmanship will know, the UK hallmark provides a unique and identifying feature to any design. Dating back to the 14th century, UK hallmarking has provided customers with a sign of excellence, origin and approval on all jewellery passed through their Assay Offices for inspection.

At Robert & Victoria we have always celebrated the hallmark and work closely with our local Assay offices to ensure each piece of our jewellery meets the strict requirements to be issued its own identifying marks. The British hallmarking system is unique and respected across the world and to showcase these identifying marks, we are proud to introduce our Hallmark collection.

Across our exclusive Hallmark Collection, all relevant Assay marks are specifically highlighted and enlarged to provide a distinctive focal point for the wearer to enjoy and demonstrate their passion for British jewellery design and hallmarking.

Each piece of the collectable Hallmark Collection carries the official assay marks of the year it was manufactured - 2022 (X)/2023 (Y)/2024 (Z), the makers/sponsors mark – Robert & Victoria (CWS), the metal standard – 9ct Gold (375) or Sterling Silver (925 & Lion) and the Assay Office – Birmingham (Anchor).

This item will arrive lovingly and securely dispatched in our elegant jewellery packaging.

Dimensions: Blue John: 28mm x 28mm.

Ring Sizing Guide

Finding the perfect fit.

With over many years experience in designing and handcrafting our own stunning collections of jewellery, we consider ourselves to be experts when it comes to finding the perfect fit, which includes a fabulous array of rings to choose from including wedding rings, engagement rings, eternity rings and diamond rings

Once you have found the ring of your dreams, the next job is to pick your ring size. Since we understand how important it is to get the ring size right, not only for comfort and style but for peace of mind too, we have created an easy to use ring sizing tool which can help guide you to finding the best ring size for you or your partner.

Our handy ring sizing guide is available to download and print in the comfort of your own home. It offers a simple, step by step guide with detailed instructions to give you an easy and effortless way to find your size without having to leave the house.

Once you have chosen the ring size suitable for you, you can either place an online order or visit us in person. Whilst we are confident that our ring sizing guide will be a valuable tool in helping to find your perfect size, please remember that the ring sizing guide tool should only be used as an estimate, and is not an exact measurement.

What if the ring size turns out to be incorrect?
In the instance that you select a ring in the incorrect size, we provide an excellent after sales service where we will offer to either resize or exchange your ring for the correct size.

Planning a surprise proposal?
Finding the ring to fit your intended's finger ahead of time can be a tricky prospect. We understand that its not always possible to bring your partner in-store for a professional ring sizing measurement, particularly if you are looking to plan a surprise proposal!

Instead, we highly recommend ‘borrowing’ one of your partner’s rings they already wear. Engagement and wedding rings and traditionally worn on the fourth finger of the left hand, but it is unlikely that your partner chooses to wear anything on this finger since its usually left bare until marriage. However, if you can find a ring that they wear on the middle finger, we can get a good idea of size and go down a size or two to find the perfect fit for their ring finger.

Jewellers tip...
We strongly advise that if you are looking to purchase a ring with a thicker style band, you select a ring one size up from your normal size. The broader the ring, the tighter the fit. We also suggest not to measure your fingers when your hands are cold, as your fingers can shrink up to half size smaller when exposed to low temperatures.
