Two Stone & Side Stone Engagement Rings

What Is a Two Stone (Toi-et-Moi) Engagement Ring?

A two stone engagement ring — historically toi-et-moi, French for ‘you and me’ — sets two stones side by side with no central stone, representing the joining of two lives. Famously Napoleon’s 1796 sapphire-and-diamond proposal to Joséphine; revived in the 2010s–20s by celebrity rings like Megan Fox’s emerald-and-diamond design.

• Bypass — the band curves asymmetrically around the two stones; the most popular configuration.
• Parallel — both stones aligned in a single row on a straight band.
• Overlap — one stone set slightly above the other for dimensional depth.

Popular Two Stone Combinations

Side Stone Engagement Rings — The Classical Accent Tradition

A side stone engagement ring features a dominant center diamond flanked by smaller accent stones along the band shoulders (typically 0.05–0.15ct each) — distinct from three-stone, where the flanking stones are large and visually equal. Side-stone accents are deliberately small, adding sparkle without competing with the center:

• Five stone — center + two flanking stones each side; symbolic in some traditions (five senses, five children, or five years).
• Seven stone — center + three each side; traditionally marks seven years.
• Diamond shoulder — small accents along the band shoulders, sometimes with milgrain edges or pavé detail.
• Where it sits — between solitaire (no accents) and three-stone (large flanking stones); for clients wanting more presence than a solitaire but lighter symbolic weight than three-stone.

Engagement Rings with Sapphire, Emerald & Ruby Accents

Colored gemstone side stones are an increasingly popular custom choice (the Princess Diana ring shows the reverse arrangement, but the principle works either way):

• Sapphire accents — the most-purchased colored side stone; deep blue Ceylon sapphire flanking a white diamond reads classical and royal. Durable for daily wear (Mohs 9); best in platinum or 18K white gold.
• Emerald accents — vivid green contrast. Softer (Mohs 7.5–8), so use protected (bezel or partial-bezel) settings; best with yellow or rose gold.
• Ruby accents — bold red, the most romantic pairing. Durable (Mohs 9); works especially well with yellow gold and round or cushion centers.

Two Stone vs Side Stone vs Three Stone & Why ATL

Three multi-stone categories with very different design philosophies:

• Two stone (toi-et-moi) — two equal stones intertwined, no center; symbolic of two lives joining. Asymmetric bypass setting reads romantic and modern. Choose for modern romantic symbolism.
• Side stone — a dominant center with small accents on the shoulders; center clearly dominant, light symbolic weight, classical and timeless. Choose for classical sparkle accents.
• Three stone — center flanked by two LARGE comparable side stones, visually equal partners; past/present/future meaning. Choose for symbolic weight. See three stone rings.

Both toi-et-moi and side-stone are among our most-requested custom categories — their asymmetric bypass and accent configurations require hand-fitting handcrafted at our Snellville, GA showroom (since 2008). We guide shape, proportion, color balance, and setting; every ring includes lifetime cleaning and prong-tightening (especially important for colored-gem care). For pairing, see diamond wedding bands or curved ring enhancers (ideal for bypass toi-et-moi).
