Eva Oval Cut Lab-Grown Alexandrite Ring in Sterling Silver

Teal by day, twilight by night. The Eva lab-grown alexandrite ring is built around a 7x9 mm oval that glows blue-green teal in daylight and turns a deep purple once the evening lights come on — the signature color-change that sets alexandrite apart from every other stone. A vintage lotus of three marquise side stones surrounds it, brightened with simulated diamond accents, in solid 925 sterling silver with a rhodium finish. One ring, two entirely different moods.

Two colors, one stone

The whole appeal of alexandrite lives in its color-change. In cool natural daylight the oval reads a fresh blue-green teal; under warm indoor light or candlelight it deepens to purple. This is not a trick of the photos — the stone is faceted and open-set, so you genuinely watch it transform as you move from a sunny window to a dinner table. For a closer look at why alexandrite behaves this way, our journal on whether synthetic alexandrite changes colors is the best starting point.

A vintage lotus setting

Three marquise-cut stones arc around the oval to shape a lotus blossom, an old symbol of purity and renewal that gives the ring its soft, antique-romantic character. Simulated diamond accents outline the petals with a fine line of white sparkle, so the flower catches light from every angle. It is a design for lovers of heirloom-style detail, and it sits naturally alongside the rest of our alexandrite jewelry. Pair it with a partner's band from our alexandrite couples rings for a matched set.

The lab-grown center

The oval alexandrite measures 7.0 x 9.0 mm, approximately 1.4 carats, and is lab-grown — the same composition and dramatic color-shift as natural alexandrite, produced in a controlled environment so the stone stays clean, consistent and affordable. At roughly 8.5 on the Mohs scale it is genuinely hard-wearing. Natural alexandrite of this size is exceptionally rare and costly; if you want to understand the trade-offs, our guide to lab-grown versus natural alexandrite spells them out honestly.

Solid sterling silver with a rhodium finish

Eva is made in solid 925 sterling silver and finished with rhodium, the same precious metal used to plate fine white gold. That finish gives the ring a bright, mirror-white shine, adds a protective barrier against tarnish and scratches, and keeps the silver looking freshly polished. It is also nickel-free and hypoallergenic, so it stays comfortable through daily wear.

Why couples choose it

A stone that changes with its surroundings is an apt symbol for a partnership that grows and shifts over time, which is part of why alexandrite has become such a beloved engagement and promise-ring choice. As a June birthstone it also makes a heartfelt birthday gift. Still weighing your options?

Sizing & care

Choose your size at checkout. If you are between sizes or unsure, we are happy to help — and if the fit isn't quite right, resizing is available and starts from a modest fee. To keep the alexandrite and rhodium finish luminous, remove the ring before showering, swimming or applying lotions, and store it in the velvet box when not worn. A soft, dry cloth revives the shine. With gentle care, Eva is built for everyday wear.
