Oval Cut Lab-Grown Alexandrite Engagement Ring in Sterling Silver

Delicate on the finger, dramatic in the light. The Olivia sets a faceted oval lab-grown alexandrite on a slim 1.8 mm band, and that little stone does something remarkable: it reads teal, blue and green in daylight, then turns deep purple and violet under lamplight and candle glow. It is a real color-shift, and because the oval is faceted and set in the open, the change is always visible — a dainty color-changing alexandrite engagement ring with more magic than its size lets on.

Dainty by design

The Olivia is built to be worn every day: a slender 1.8 mm band and a neat oval that sits close to the finger, elegant enough to layer and light enough to forget you have it on. It is vintage-inspired without being fussy — the sort of quiet piece that earns a second glance only when the light shifts. If a delicate silhouette is what you’re after, you’ll find more to love across our alexandrite engagement rings, and it stacks beautifully with a plain band from our alexandrite wedding bands.

The color-shift, front and center

Alexandrite’s party trick is real physics: trace chromium in the crystal absorbs yellow-orange light, so under blue-rich daylight the oval reads teal, blue and green, while under red-rich incandescent or candlelight it shifts to purple and violet. The Olivia’s stone is faceted and open-set, never buried in resin, so you actually watch the color travel as you move from daylight to evening. If you’re curious how convincingly a created stone pulls this off, our journal on whether synthetic alexandrite changes color is worth a read.

The lab-grown alexandrite center

The 7 x 9 mm oval (about 1.4 ct) is genuine lab-grown alexandrite — the same chromium-traced chrysoberyl as mined alexandrite, matching its 8.5 Mohs hardness and full color-change, simply created in a lab. Since natural alexandrite of this size is one of the world’s costliest gems, a lab-grown center is what makes a color-shifting everyday ring like the Olivia possible. For the full breakdown, see our guide to lab-grown vs natural alexandrite.

Simulated diamond accents

Fine simulated diamond (CZ) accents add a crisp flash of white sparkle beside the oval, sharpening the outline and making the alexandrite’s shifting color read even brighter. It is a clean, brilliant way to add a little extra light to a delicate design without overwhelming it. Prefer moissanite or natural-diamond accents? Let us know and we can tailor the Olivia for you.

Solid sterling silver with a rhodium finish

The Olivia is crafted in solid 925 sterling silver finished with rhodium, the bright white metal used on fine white gold. That finish gives a tarnish-resistant, mirror-white luster and a protective layer against everyday scratches, so a slim silver band wears far above its price. The cool white tone is also the perfect neutral backdrop for alexandrite, letting the teal and violet read at full saturation.

What alexandrite symbolizes

A stone that shifts with the light makes a tender emblem for a love that changes and grows — alexandrite has long stood for transformation, balance and new perspective, which is exactly why the Olivia feels so personal. As one of the three traditional June birthstones, it also makes a heartfelt June birthday gift. Torn between this and another blue-violet gem? Our comparison of alexandrite vs sapphire shows why the color-change makes it feel truly one of a kind.

Sizing & care

Choose your size at checkout; if you’re between sizes or unsure, reach out before you order and we’ll help — the Olivia is handmade to order, so please allow 3–5 weeks for production. Resizing is available afterward and starts from a modest fee. To keep the color-shift vivid and the rhodium bright, remove the ring before showering, swimming or applying lotions, store it in its box, and buff with a soft dry cloth. At 8.5 Mohs the alexandrite is well suited to everyday wear.
