Ava Oval Cut Alexandrite Engagement Ring in Sterling Silver

Step outside and it glows a cool teal blue-green; step back into candlelight and it blooms into purple-red violet. That living color shift is the whole point of this oval cut alexandrite engagement ring — a 7 × 9 mm lab-grown alexandrite of roughly two carats, cradled in an open setting so daylight and lamplight can play across every facet. Framed by simulated diamonds and set in solid 925 sterling silver with a bright rhodium finish, it is a June-birthstone ring that quietly reads as two different gems in a single day.

A stone that changes with the light

Most gemstones show you one color for life. Alexandrite shows you two. Under daylight or cool office lighting the oval center reads teal to blue-green; move into warm incandescent light, candlelight or a sunset and it turns toward purple, violet and soft raspberry-red. Because the stone sits in an open oval setting rather than a closed bezel, that shift is easy to see in person — a small piece of theatre on your hand. If you love the idea of a gem that never looks quite the same twice, the wider world of alexandrite engagement rings is built around exactly this magic, and our guide to whether synthetic alexandrite changes color explains the science in plain language.

The lab-grown alexandrite center

The oval is lab-grown alexandrite — real chrysoberyl with the same chemistry, the same Mohs 8.5–9 hardness and the same chromium-driven color change as mined alexandrite, grown under controlled conditions instead of pulled from the earth. At this size that origin matters: natural alexandrite above a carat is one of the rarest and most expensive gems on the planet, so lab growth is what makes a full two-carat, full-shift stone something you can actually wear. If you want to understand the trade-offs before you buy, our feature on lab-grown versus natural alexandrite is written for exactly this decision.

A frame of simulated diamonds

Slender simulated diamond accents trace the setting, adding a crisp ribbon of white sparkle that makes the alexandrite’s teal-to-violet shift read even cleaner against the silver. It is a bright, budget-friendly way to bring classic engagement-ring shimmer to the design without competing with the color-change star at the center.

Solid sterling silver with a rhodium finish

The band is crafted in solid 925 sterling silver and finished with rhodium, the same precious white metal used on fine white-gold jewelry. That rhodium finish gives the ring a bright, mirror-white luster and adds a protective shield that helps resist tarnish and everyday scratches, so the silver keeps its freshly polished look. At a delicate 1.8 mm the band stays elegant on the finger and pairs beautifully with pieces from our alexandrite jewelry range.

What alexandrite symbolizes

Alexandrite is the modern June birthstone and, because it transforms with its surroundings, it has long been read as a stone of balance, adaptability and joy — a fitting emblem for two people learning to grow together. Its dual nature also makes it a meaningful choice for a promise ring or an anniversary gift for a partner who contains multitudes. Couples drawn to matching pieces often pair it with something from our alexandrite couples rings, and if you are weighing it against a classic blue stone, our comparison of alexandrite versus sapphire is worth a read.

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 both the alexandrite and the rhodium finish at their brightest, remove the ring before showering, swimming or applying lotions, and store it in the velvet box when not worn. A soft, dry cloth restores the shine beautifully. With gentle care, this is a ring made to be worn every day.
