Step 2: Receive Your Moodboard

Based on your vision, Antonia will then prepare a visual moodboard of design concepts and suggested stone options, along with relevant costings for your approval.

Step 3: Select Your Stones

Having chosen a design direction, the next step is to select the perfect stones for your piece. We only source our stones from trusted suppliers.

Step 4: Visualise Your Design

Once you have chosen your stones you will work closely with Antonia to create the perfect, hand drawn 2D design. Our team will then produce a 3D render of the final piece for your approval.

Step 5: Bring To Life

The final stage of the journey is the casting and hand-setting of your piece in your chosen metal by our talented Goldsmiths in our Melton Mowbray workshop.

Client Love; Testimonials from past Clients

I contacted Antonia when it became apparent that my engagement ring no longer fitted me and further enlargement would damage the structure. She assisted me with the decisions every step of the way and everything was always on schedule. Needless to say I absolutely love the end result and couldn’t recommend Antonia and her team highly enough.

5* Trustpilot Review

Where to start! I came to Antonia slightly overwhelmed about where to even start when it came to engagement rings. No matter how much research I did, as soon I thought I understand one thing about it all, another thing to add to the equation popped up, and I was back to square one! Antonia was amazing at really simplifying what seemed like a daunting task. From the outset her knowledge and passion really showed, taking time to really understand what I was looking to achieve. Always there for when I needed advice throughout the process, allowing me to have my say in the design details, never pushing me to make a decision, and keeping in touch with me regularly, all amounted to a very happy customer! For something that is a once in a lifetime experience - and a once in a lifetime piece of jewellery - if anyone is looking for an engagement ring to be designed and created, Antonia Guise is the one! I couldn’t recommend her enough!
