Complete Description
A Toi Et Moi engagement ring built around two square emerald cut diamonds, set side by side in 18k white gold. The name is French for "you and me" — a centuries-old design tradition where two stones share one ring, representing two lives joined together.
The center stones are matched in size but distinct in personality. The larger of the two is 1.55ct, D color, SI1 clarity — D being the highest color grade a diamond can earn, signifying complete colorlessness. Its companion is 1.54ct, E color, VS2 clarity — also in the colorless range, with clarity high enough that any inclusions are invisible to the naked eye. Both diamonds are GIA certified.
Surrounding the center stones is 5.70ct of round brilliant cut diamonds in F–G color, VS clarity, which extend the brilliance outward. A 2.30ct baguette cut diamond halo frames the outermost edge, adding architectural geometry to the design. In total, the ring carries nearly 11 carats of diamond weight while remaining wearable on a single finger.
The square emerald cut — sometimes called an Asscher-adjacent step cut — produces a distinctive "hall of mirrors" optical effect rather than the rapid sparkle of a brilliant cut. Light moves through the stone in long parallel flashes, which reads more measured and architectural than fiery. Pairing two of them in a Toi Et Moi setting amplifies that effect: the eye reads the two stones as a single luminous shape from a distance, then resolves them into two distinct centers up close.
Who this ring is for
This is a high jewelry piece, well-suited to clients who want an engagement ring with intentional symbolism beyond the standard solitaire — the two-stone format makes it a meaningful choice for couples who want their ring to tell a story. It also wears beautifully as a right-hand statement ring or a milestone anniversary piece, and it pairs naturally with a thin diamond wedding band or stacked eternity bands.

Frequently Asked Questions
Toi Et Moi means "you and me" in French. It's a ring style featuring two prominent center stones set side by side, symbolizing two lives joined together. The design dates back to the 18th century — Napoléon famously gave Joséphine a Toi Et Moi engagement ring in 1796 — and has had a strong contemporary revival as a meaningful alternative to the single-stone solitaire.
The center stones are 1.55ct D-SI1 and 1.54ct E-VS2 — both in the colorless range (D and E are the top two color grades), with clarity grades that read eye-clean. Diamonds are graded individually, and matching two stones perfectly across all 4Cs is rare. We selected stones that match in size and visual appearance while remaining within the highest-quality range. Both are GIA certified.
A square emerald cut is a step-cut diamond with parallel facets running across the stone, similar to the rectangular emerald cut but in a square outline. It's closely related to the Asscher cut. Step cuts produce a distinctive "hall of mirrors" optical effect — light reflects through the stone in long parallel flashes rather than the rapid sparkle of a brilliant cut, giving the diamond a more measured, architectural character.
The piece as listed is size 7. Resizing for a Toi Et Moi setting requires careful work to preserve the side-by-side stone arrangement. Contact us before purchase to discuss sizing, and we'll confirm what's possible for your size.
