Make your jewellery even more personal ✨

One of my customers wanted to add a touch of aquamarine to my Linear ring, creating a piece that feels even more meaningful and personal to them.

I love working with customers to incorporate birthstones, favourite gemstones, or special details that tell their story.

If you've fallen in love with one of my designs but would like to make it your own, I'd love to hear your ideas.

A little piece of the night sky ✨

The perfect ring for a starry night - crafted in 18ct yellow gold, set with round brilliant cut diamonds and finished with delicate star details. A soft frosted finish gives this piece an enchanting glow from every angle 💫

This ring is also very special because it was my customers father's wedding ring. We compressed it down to her size so she didn't loose any gold, frosted the surface, set diamonds and hand engraved the sparkling stars. ❤️
