    I had a great experience with this custom CAD design service! I shared photos of my engagement ring, and they quickly created a beautiful wedding band design that matched it perfectly. The communication was prompt throughout, and they provided high-quality rendered images along with all the necessary details, including sizing and dimensions. The whole process was smooth and professional. I’m really happy with the design and will definitely be getting my ring manufactured with them soon. Highly recommend if you’re looking for a custom, well-thought-out ring design!

    The ring is absolutely beautiful in every way. Thrilled with how it turned out. There was open communication throughout the whole process- when I asked for video- it came quickly! I got to see photos of the setting after it had been crated and after the diamond had been set. One of the reasons I chose this store was I liked the thinner bezel around the stone and the finished product is comparable to the advertised photo. This has been such a wonderful experience. We love the ring and I’m excited to have this beautiful piece of jewelry on my finger every day.

    Beautiful ring, fits perfectly and is very comfortable to wear daily. Soumil was amazing from even before making my purchase by answering my many questions and helping me decide on what the correct size could be. The process was seamless from start to finish. I was updated throughout every step and I could not be happier. Soumil was very kind, patient, helpful and happily addressed my every question and the final ring is even better than I could have imagined. The cherry on top is the certificate that I received of every detail of the ring which I appreciate and is useful to have. Will definitely love to make a purchase in the future and have already recommended to friends that are looking to design some pieces.

Knowing that you felt supported throughout the process means just as much to us as hearing how much you love the finished piece.

    Soumil was incredible and had wonderful customer service. I am so thrilled with the ring. Its exactly what I wanted and More. I was quite particular about the shade of stone I wanted and he was an expert guiding me to find the right stone colour. He took time to pinpoint the exact shade and understood what I wanted and made sure I was happy throughout. He kept me up to date with updates throughout. I cant put into words how grateful and happy I am. the ring came in a beautiful box and was such a treat to open. Massive massive thank you

    I was offered the option to get a 3D Print for a custom ring that is currently in production. It was an excellent way to see how the ring would look before beginning the process of making the ring. It gave me the chance to see the ring much better compared to CAD Designs alone and to revise the style of the ring when needed. It was very helpful and gave me piece of mind that I was getting everything I wanted included with the design of the ring. I would definitely recommend using the 3D Print option to see how you envisioned your customized item of jewelry will look before committing to the production of the jewelry you want created.

    Soumil

    Soumil responded on Jun 22, 2026

    Sarah, Thank you for taking the time to share your experience. We're delighted that the 3D prototype gave you the opportunity to see the design in person before production and make refinements with confidence. Custom jewellery is a collaborative process, and we believe having the chance to review a physical model can make all the difference when creating something truly personal. Thank you as well for all of your thoughtful feedback throughout the project. It's been a pleasure working with you, and we're excited to continue bringing your jewellery ideas to life. — London Diamond Studio

    Absolutely beautiful earrings!!! Excellent quality and exactly what I ordered. The best customer service I have ever had compared to other sellers! Somil goes beyond great customer service and is very helpful with giving his thoughts and opinions when customizing jewelry. He updated me during the entire process of making the earrings and included photos to make sure the earrings were exactly what I had envisioned. In addition, very fast shipping without any delays with customs or duty fees to be paid for delivery to the US. Please do not hesitate to purchase from him. His insight alone and the quality of his jewelry is worth every penny. Thank you so much, Somil! It was a pleasure working with you!

    The most helpful jeweller I have ever dealt with. Throughout the process I was reassured, at every step. The price made me a bit careful. I thought there’s no way this can be as good as it seems but it is actually better. The personal touch, the tending to my ever need and the care was exceptional. Genuinely, can’t imagine why you would use another jeweller.

    Soumil responded on Jun 8, 2026

We know ordering a bespoke piece online can feel like a big decision, so we’re delighted that you felt reassured every step of the way. Thank you for placing your trust in us, and for taking the time to share your experience. Wishing you both every happiness for the future.
