T + A

When T approached Antonia to create the perfect ring to symbolise their Story, he knew it has to be something classic, yet distinctive. The finished ring is a masterpiece that showcases the beauty and rarity of the centre stone while adding a modern twist that reflects the couple's contemporary style.

At the heart of this ring is the mesmerizing yellow diamond, a symbol of the warmth, joy, and light that T+A bring to each other's lives. The cushion cut highlights the stone's unique character, while the VVS1 clarity ensures an unparalleled brilliance that takes the breath away.

Surrounding this exceptional centre stone are two round diamond side stones, in a mixed metal setting that adds a touch of modern elegance to the classic trilogy design.  The combination of metals creates a stunning 'floating' effect, making the side stones appear to hover gracefully around the yellow diamond

The design journey


Whatever the occasion and inspiration, your journey begins by meeting Antonia for a chat to share your initial ideas and unique Story.


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.


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.


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.


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.
