Alliances Alexandrite

Alexandrite makes an excellent and distinctive wedding ring, valued for its rare color-change from green to purple and its Mohs 8.5 hardness, which is well-suited to everyday wear — harder than most colored gemstones. Its transformation makes a meaningful symbol for an enduring marriage, and as a June birthstone alternative it adds personal significance. Because natural alexandrite is very rare, lab-created alexandrite is commonly used and disclosed honestly. See our June birthstone collection.

Alexandrite changes color because of the way it absorbs light — it appears green in daylight or fluorescent light and shifts to purple-red under incandescent or candlelight. This rare optical property, caused by trace chromium in the stone, is what makes alexandrite so prized and so symbolic for a wedding ring, representing a love that holds true in every light. Both natural and lab-created alexandrite show this effect.

An alexandrite wedding ring is very durable, as alexandrite scores 8.5 on the Mohs scale — harder than most colored gemstones and well-suited to everyday wear over a lifetime. This durability is one of alexandrite's biggest advantages as a colored bridal stone. Standard protective settings and gentle cleaning with warm soapy water keep it beautiful; see our jewelry care guide.

Both natural and lab-created alexandrite are used in wedding rings, and Aquamarise® discloses which on every listing. Natural alexandrite is one of the rarest and most expensive gemstones in the world, so lab-created alexandrite — which shows the identical color-change at a far more accessible price — is widely used in fine jewelry. Both are genuine alexandrite with the same optical properties and durability.

Every metal flatters alexandrite's color-change, so the choice is aesthetic. White gold and sterling silver keep both color phases crisp, yellow gold vermeil warms the stone, and rose gold emphasizes its purple shift. Genuine 925 sterling silver will not turn skin green. See our precious metal guide.
