Ring story · You and me

Two stones,
one love story.

The Toi et Moi London Blue Topaz & Lab Alexandrite Ring by Brilliant Earth sets two very different stones side by side in 18k yellow gold — a deep teal topaz and a colour-shifting lab alexandrite. Two souls, distinct yet inseparable, in one dazzling design.

Who she is

For the woman who wants
colour and meaning.

This is the one I pull for the couple who love a symbol. A toi et moi (“you and me”) ring pairs two stones for two people, so it’s romantic in a way a single solitaire simply isn’t.

She’s drawn to unusual colour and a little magic — the alexandrite’s colour-shift and the topaz’s deep teal make this ring feel personal and one of a kind.

Two souls side by side — distinct, but inseparable. The whole idea of a partnership, in one ring.
What sets it apart

Three things that make it
meaningful.

01

A romantic toi et moi

Two stones sit side by side in the classic “you and me” design — a centuries-old romantic motif representing two people coming together. Symbolism you can see and wear every day.
Why toi et moi
Two stones for two people — a romantic design famously used by Napoleon and Jackie Kennedy, made colourful and modern here.
02

Deep teal London blue topaz

The London blue topaz exudes calm, grounded confidence in a deep, timeless teal — a rich, saturated colour that anchors the pairing beautifully.
03

Colour-shifting lab alexandrite

The lab-grown alexandrite dazzles with its colour-shifting magic, representing transformation and the unexpected. Together the two stones capture both harmony and individuality.

In real life

Colourful, and made for
everyday wear.

Blue topaz and alexandrite are both nicely wearable, and the two-stone setting keeps them secure and relatively low-profile. A little gentle care — off for rough tasks, a soft clean — keeps the colours vivid. It pairs neatly with a plain band, and its meaning makes it a joy to wear daily. A colourful, story-rich everyday ring.

Common questions

FAQ — what people
actually ask me.

What does a toi et moi ring mean?

Toi et moi means “you and me” — two stones representing two people coming together. It’s a romantic, historic design, which makes it a beautifully meaningful engagement ring.

What is alexandrite known for?

Alexandrite is famous for its colour-shifting magic, appearing different hues in different light — a symbol of transformation and growth, and a genuinely unusual, eye-catching stone.

Are these stones durable for everyday?

They’re wearable with a little care. Both are reasonably hard but softer than a diamond, so it’s best to avoid knocks and harsh chemicals and clean gently.

Can this be an engagement ring?

Absolutely — a colourful toi et moi makes a meaningful, individual engagement ring for someone who wants symbolism and colour over a traditional solitaire.
