A natural diamond, a piece of 18ct yellow gold, and a lot of time at the bench.
This marquise cut solitaire was completely handmade in our London workshop, from the construction of the setting to the final finishing.
There’s something about a marquise diamond that never feels ordinary — elegant, slightly dramatic and beautifully elongated.
No mass production. No shortcuts. Just a natural diamond set into a piece made properly, by hand.

This bespoke three-stone engagement ring features a striking emerald-cut centre diamond, complemented by tapered baguette-cut diamonds set into a rich 18ct gold band. The clean geometry of the step-cut diamonds creates a refined architectural aesthetic, while the warm gold provides a timeless contrast to the brilliance of the stones.
Handmade with precision and attention to proportion, this custom diamond engagement ring is a contemporary interpretation of a classic three-stone design.
Designed and crafted by Karl Karter, a London jewellery artist and goldsmith with over 30 years of experience, creating bespoke engagement rings and handmade fine jewellery in Hatton Garden, London.

Things are changing at London Rocks…
After years of making jewellery, building the business and learning what actually works, I’m making some big changes. Growth isn’t always about getting bigger — sometimes it’s about getting better, more focused and more true to what you actually want to create.

More design. More experimentation. More handmade work. More of the jewellery that excites me.

The next chapter is already underway. ⚒️💎
