Complete Description
Two marquise-cut lab-grown diamonds in a bypass setting — the band wraps and crosses so the stones angle past each other in opposing directions, creating a dynamic Toi Et Moi silhouette that reads modern rather than traditional. Available in 14k yellow, white, or rose gold, in seven carat weight options from 4ct to 15ct total weight, starting at $3,220.
Every diamond is DEF color and VS clarity with an excellent cut grade — both stones in each pair hand-matched for size and visual consistency. The bypass construction means the two marquises sit at slightly different elevations on the finger, with each stone tipped in opposing directions — when worn, the design reads as movement rather than static symmetry.
Why "Toi Et Moi"
Toi Et Moi (French for "you and me") is a two-stone engagement ring tradition dating to the 18th century, when Napoleon proposed to Joséphine with a Toi Et Moi sapphire and diamond ring. The two stones traditionally represent two lives or two souls joined together — making it a meaningful choice for engagement, anniversary, or any milestone marking a partnership. Two marquise diamonds in a bypass setting is a less traditional pairing than the classic round-and-pear, but the angular geometry of marquises and the asymmetric flow of the bypass create a contemporary read.
Choosing your scale
The carat options refer to total weight across both stones — so 4ct gives you two 2ct marquises, 8ct gives you two 4ct marquises, and so on. This piece starts at 4ct (rather than the typical 1-2ct floor for traditional engagement rings) because marquise stones at smaller weights lose visual impact in a Toi Et Moi configuration — the design works best at scale. At 4-6ct, the ring reads as a substantial daily engagement ring. At 10ct+, it becomes a statement piece.
How it pairs with a wedding band
A bypass Toi Et Moi setting creates one of the more deliberate wedding band pairings because the asymmetric construction means straight bands sit unevenly against the engagement ring. Two approaches work well:
- A contoured (curved) wedding band shaped to nest against one side of the bypass
- A thin pavé eternity worn slightly offset to avoid the higher prong points
- Or skip the band entirely — bypass Toi Et Moi rings often work best worn solo, with the bypass itself reading as the architectural statement

Toi Et Moi is French for "you and me." The two-stone ring tradition dates to the 18th century, when Napoleon proposed to Joséphine with a Toi Et Moi sapphire and diamond ring. The two stones traditionally represent two lives or two souls joined together — making it a meaningful choice for engagement, anniversary, or any milestone marking a partnership.
Marquise-cut diamonds rely on their elongated shape for visual impact. At smaller carat weights, marquises lose the architectural presence that makes the cut distinctive — especially in a Toi Et Moi configuration where two stones share the design. Starting at 4ct total (two 2ct marquises) ensures the ring carries the design integrity at every selectable size.
A bypass setting is a ring style where the band wraps around the finger so that the two ends "bypass" or pass beside each other rather than meeting at a single point. On this ring, the band wraps so the two marquise stones sit at slightly different angles, with each stone tipped in opposing directions — creating a sense of motion rather than the symmetry of a traditional side-by-side Toi Et Moi.
A bypass Toi Et Moi creates more deliberate band pairings than a flush solitaire because the asymmetric construction means straight bands sit unevenly against the engagement ring. The most popular pairings are a contoured (curved) wedding band shaped to nest against one side of the bypass, or a thin pavé eternity worn slightly offset. Many bypass Toi Et Moi wearers choose to skip the wedding band entirely and let the engagement ring stand alone — the bypass reads as enough architectural statement on its own. We're happy to recommend specific bands once you've selected your engagement ring.
Yes. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds — the only difference is how they're produced. They're graded on the same 4Cs standard (cut, color, clarity, carat weight) and have the same hardness (Mohs 10) and brilliance.
