The Holts Gems Bespoke Process
Our bespoke engagement ring process is designed to be as enjoyable as the result. It begins with a relaxed design consultation — available in our London showroom or remotely — where we take the time to understand your style, preferences, and budget. From there, our designers create detailed sketches and computer-aided design visuals so you can see exactly how your ring will look before a single piece of metal is cut or stone is set.
Once you are completely happy with the design, our master craftspeople get to work, hand-finishing every element to perfection. Most bespoke rings are completed within four to six weeks, though we can accommodate shorter timelines for those with imminent proposals. Throughout the process, you will receive regular updates and have the opportunity to review progress, ensuring the final piece exceeds your expectations.

Premium Diamonds and Gemstones
At the heart of every great engagement ring is a truly exceptional stone. Holts Gems offers access to an impressive selection of certified diamonds and precious gemstones, sourced responsibly and selected for their outstanding quality. Whether you are drawn to the brilliance of a round diamond, the drama of an oval, the romance of a ruby, or the cool allure of a sapphire, we will help you find the perfect centrepiece for your ring.
All diamonds are independently certified by leading gemmological bodies including the GIA and IGI, giving you complete confidence in the quality and value of your purchase. Our gemmologists are on hand to guide you through the four Cs — cut, colour, clarity, and carat — ensuring you get the best possible stone within your budget. We also offer ethically sourced lab-grown diamonds for those who prioritise sustainability without compromising on quality.
