Timeless motion. Considered from the ground up.

Obsidian
The Uncut Collection
Obsidian

Volcanic glass formed under intense pressure. Appearing dark and ordinary — razor-sharp and exceptional beneath the surface.

Our story

Value is often hidden in plain sight.

Marbles & Diamonds London draws its name from a simple story.

Two young children in Africa playing a game of marbles — unaware they were holding diamonds.

It is a reminder that value is often hidden in plain sight. That what appears ordinary can, in fact, be exceptional.

The brand was built on that philosophy.

We design essentials with intention. Pieces that feel understated, yet perform when it matters. Crafted for sustained durability, refined comfort, and timeless motion.

Comfortable under pressure.

Built with
intention.
Designed
to last.
Our mission

As the brand grows, so does its responsibility.

A portion of every purchase supports long-term opportunity for disadvantaged young people — beginning in Ghana — with the goal of expanding access to technology and education over time.

Built with intention. Designed to last.
