At Roses&Co., we craft enduring jewellery designed for a life well-lived, blending London-based design with the rigour of British standards. Every piece is independently tested and Hallmarked at the London Assay Office, providing a 700-year-old guarantee of metal authenticity that lasts a lifetime. We exclusively use CVD technology to create diamonds that are chemically, physically, and optically identical to mined stones—real diamonds, defined by science rather than extraction. This fusion of heritage craftsmanship and modern innovation ensures that each hand-selected stone possesses the fire of a traditional diamond, delivered with a modern, ethical conscience.

We believe the acquisition of fine jewellery should be a seamless experience, which is why every Rosesco piece is delivered with our compliments to any address within the United Kingdom. To ensure every detail is perfect, our studio prepares and dispatches all in-stock pieces within five working days, utilizing fully insured and tracked couriers for your absolute peace of mind. For selections currently out of stock, please allow a lead time of three to four weeks. Our concierge team will contact you directly with a personal update, ensuring your journey with us remains as refined as the collection itself.

We offer a straightforward 30-day return and exchange policy for our clients. From the moment you sign for your delivery, you have a full month to ensure you are 100% satisfied. While we hope you fall in love instantly, you have the freedom to request a different piece or a full refund within this window.

A piece of Rosesco jewellery is designed to be an enduring companion, crafted by our London-based artisans to remain a cherished heirloom for years to come. We stand behind the integrity of our work with a lifetime commitment to quality; in the rare event that a piece reveals a manufacturing defect, we will gladly restore, repair, or replace it to ensure its story continues. Should your jewellery require such attention, all shipping and care will be managed by our studio with our compliments, providing you with seamless assurance for the life of your piece.

The arrival of a Roses&Co. piece is designed to be a sensory experience, where the journey begins with the refined weight and texture of our signature packaging. Your selection is housed within a bespoke, cream-toned vegan leather case—a soft-touch, structured home finished with a subtle gold clasp. To ensure an elevated discovery, each order is presented in a beautifully coordinated gift bag with a hand-tied silk ribbon and dispatched in understated, unbranded outer layers, ensuring your acquisition remains a private, pristine discovery until the moment it is unveiled.

    How to Measure Your Ring Size?

    Let’s check out this Chart!

    The following chart will be helpful for you to get the exact size of your ring. You can either make use of a small piece of string/paper or a tape to measure the area that will be occupied by the ring. When it becomes a complete circle, make a mark on the string. This will be helpful for you to compare with the chart that is mentioned below. For extra width, you can add another size to accommodate.

    Step 1

    Take a thin thread or strip of paper.
    Wrap the thread or paper around your finger.
    Mark the meeting spot of the thread/paper’s end.

    Step 2

    Measure the length of the thread/paper on a scale.
    Use the following chart to determine your ring size.
