Toi Et Moi Alexandrite and Diamond Engagement Ring in 925 Sterling Silver

Two stones, two souls — and one of them refuses to sit still. In this Toi Et Moi alexandrite and diamond ring, a pear-cut color-changing alexandrite leans toward a clean emerald-cut simulated diamond, the pair curving past each other like a couple mid-embrace. The faceted, open-set alexandrite glows teal-blue in daylight and shifts to purple-violet in warm light, so the ring literally changes character with the room. It is all set in rhodium-finished 925 sterling silver.

The color-change at the heart of the pair

Half of this ring’s magic is the alexandrite’s shifting color. Because the pear-cut stone is faceted and set open to the light, the effect is fully visible: cool teal-to-blue in daylight or fluorescent light, deepening to a romantic purple-violet under warm lamps or candlelight. Against the steady white brilliance of its emerald-cut partner, the alexandrite’s changing hue feels alive — a quiet metaphor for two people who bring out different sides of each other. To understand why the stone behaves this way, our note on how synthetic alexandrite changes colors is a great primer, and you can browse kindred pieces in our alexandrite engagement rings.

The Toi Et Moi story

Toi Et Moi — French for “you and me” — is a two-stone design in which a pair of gems sit side by side, each representing one half of a partnership. Made famous by historic royal and celebrity engagements, it has become one of the most romantic non-traditional silhouettes a couple can choose. Here the two contrasting shapes, a soft pear and a crisp emerald cut, balance each other perfectly. If you love the symbolism of paired stones, you will find more of it across our alexandrite couples rings.

An honest note on the stones

One stone is a lab-grown alexandrite — a genuine alexandrite gem created in controlled conditions rather than mined, with authentic color-change, real hardness and a clean, conflict-free origin. Its partner is a simulated diamond in an emerald cut, chosen for its crisp, glassy-clean sparkle and step-cut clarity that plays beautifully off the color-shifting alexandrite. If you are weighing grown against mined, our guide to lab-grown versus natural alexandrite lays out the essentials. Prefer a lab-grown diamond or moissanite in place of the simulated stone? Reach out before ordering and we will tailor it.

Sterling silver with a rhodium finish

The ring is crafted in solid 925 sterling silver on a slim, elegant 1.5 mm band and finished with rhodium — the same bright plating used on fine white gold. The rhodium finish gives a mirror-white luster that suits both the cool flashes of the alexandrite and the clean fire of the emerald cut, and it adds a protective shield against everyday tarnish and scratches. The ring is nickel-free and hypoallergenic, and genuine rhodium-finished silver will not turn your skin green.

Meaning & occasion

With its “you and me” symbolism and alexandrite’s long association with transformation and balance, this is a deeply personal engagement, promise or anniversary ring — and a favorite for June babies, since alexandrite is one of June’s birthstones.

Sizing & care

Choose your size at checkout. If you are between sizes or unsure, we are happy to help, and if the fit is not quite right, resizing is available and starts from a modest fee. To keep the color-change vivid and both stones sparkling, clean gently with warm water, a drop of mild soap and a soft brush, then dry with a lint-free cloth. Store it separately to protect the rhodium finish, and remove it before swimming, harsh chemicals or heavy manual work.
