It looks like an heirloom that has always changed its mind about its color. The Nesta centers on a faceted oval lab-grown alexandrite that reads cool teal and blue-green by daylight, then turns purple-red and violet under lamplight and candle glow — a true color-shift, set high and open so the change is visible, not hidden. A hand-detailed cubic zirconia halo and fine milgrain frame it in 925 sterling silver with a rhodium finish, giving this vintage alexandrite engagement ring the romance of an antique and the sparkle of something brand new.

A vintage silhouette, softly detailed
The Nesta borrows from antique and art-deco jewelry: a haloed oval, milgrain beading along the edges and marquise-inspired detailing at the shoulders. It is ornate without being heavy — the kind of ring that looks handed down rather than bought. That heritage character sits comfortably beside the rest of our alexandrite engagement rings, and pairs naturally with matching bands from our alexandrite couples rings when you’re ready to stack.
The color-shift at the heart of it
Alexandrite is the great chameleon of the gem world. Its trace chromium absorbs yellow-orange wavelengths, so under blue-rich daylight or fluorescent light the oval reads teal to blue-green, while under red-rich incandescent or candlelight it swings to purple-red and violet. This is a faceted stone in an open halo, not crushed stone in resin, so you genuinely see the shift as the light around you changes. Curious how a created stone reproduces it so faithfully? Our journal on whether synthetic alexandrite changes color walks through it.
The lab-grown alexandrite center
The 6 x 8 mm oval is genuine lab-grown alexandrite — identical in chemistry, hardness (8.5 Mohs) and color-changing optics to mined alexandrite, just created in controlled lab conditions. Natural alexandrite this size is one of the world’s rarest and priciest gems, so a lab-grown center is what makes a vintage-style color-changer like this attainable. Our guide to lab-grown vs natural alexandrite covers exactly what that means for shoppers.
The cubic zirconia halo
A halo of high-grade cubic zirconia rings the center stone, adding a crisp, brilliant sparkle that frames the alexandrite and makes its color-shift pop against the white fire. It is a bright, beautifully cut accent that keeps the ring accessible while looking every bit the part. Prefer moissanite or natural-diamond accents? Message us before ordering and we can tailor it.
Solid sterling silver with a rhodium finish
The Nesta is crafted in solid 925 sterling silver and finished with rhodium, the same white metal used on fine white gold. The finish delivers a mirror-bright luster and a protective layer that helps resist tarnish and everyday scratches, keeping the milgrain crisp and the silver freshly polished. It is also hypoallergenic and nickel-free, kind to sensitive skin.
What alexandrite symbolizes
A gem that transforms with the light is a fitting symbol for a partnership that keeps revealing new facets. Alexandrite has long been linked to transformation, balance and adaptive love, and as one of the three traditional June birthstones it doubles as a heartfelt June birthday piece. If you’re weighing it against another blue-violet favorite, our comparison of alexandrite vs sapphire explains why the color-change gives it the edge in character.

Sizing & care
Select your size at checkout; if you’re unsure or between sizes, contact us and we’ll guide you. Resizing is available and starts from a modest fee, though a halo setting is best resized by a skilled jeweler. To keep the color-shift and rhodium at their brightest, remove the ring before showering, swimming or applying lotions, store it in its velvet box, and buff gently with a soft dry cloth. With everyday care the Nesta stays luminous for years.
Frequently asked questions
Does the alexandrite really change color?
Yes. The faceted oval reads teal and blue-green in daylight and shifts to purple-red and violet under warm indoor light or candlelight. It is set high and open in the halo, so the color-shift is genuinely visible as your lighting changes.
Why does alexandrite shift color?
Trace chromium in the crystal absorbs yellow-orange light. Blue-rich daylight leaves the stone reading green-teal, while red-rich indoor light leaves it reading purple-violet. It is the same optical effect in natural and lab-grown alexandrite.
Is the alexandrite genuine?
Yes — it is real lab-grown alexandrite, identical to mined alexandrite in composition, 8.5 Mohs hardness and color-changing optics. It was created in a laboratory rather than pulled from the ground, which is the only difference.
Why choose lab-grown alexandrite?
Natural alexandrite this size is one of the rarest and most expensive gems on earth. A lab-grown center gives you the same color-shift and durability at a fraction of the cost, which is what makes a vintage-style ring like this attainable.
What are the halo stones?
The halo is set with high-grade cubic zirconia — a crisp, brilliant simulated accent that frames the alexandrite and makes its color pop. If you’d prefer moissanite or natural-diamond accents, contact us before ordering for a custom quote.
What makes it look vintage?
The milgrain beading, marquise-inspired shoulder detailing and haloed oval are all drawn from antique and art-deco jewelry. Together they give the ring an heirloom character while the CZ halo keeps it bright and sparkling.
What metal is it made from?
Solid 925 sterling silver finished with rhodium, the same white metal used on fine white gold. It is bright, protective and hypoallergenic.
What does the rhodium finish do?
Rhodium gives the silver a mirror-white, white-gold-like luster and adds a protective layer that helps resist tarnish and scratches, keeping the milgrain detail crisp and the ring freshly polished.
Is it good for sensitive skin?
Yes. The Nesta is hypoallergenic and nickel-free, both in the sterling silver base and the rhodium finish, so it is a comfortable choice for sensitive skin.
Is alexandrite durable enough for daily wear?
Yes. At 8.5 on the Mohs scale alexandrite is one of the hardest colored gems used in engagement rings, just below sapphire and ruby, so it stands up well to everyday wear with normal care.
Is alexandrite a June birthstone?
Yes — it is one of the three traditional June birthstones, so this ring makes a meaningful June birthday gift as well as an engagement or anniversary piece.
Can a halo ring be resized?
Yes, within reason. A halo setting is best resized by a skilled jeweler to protect the stones. Resizing is available and starts from a modest fee; order your correct size from the start where you can.
Are the stones ethically sourced?
Yes. All of our stones are ethically sourced and conflict-free, so you can wear the Nesta with complete peace of mind.
Does it arrive gift-ready?
Every order ships in a free luxury velvet gift box with a lifetime warranty. It pairs beautifully with pieces from our alexandrite jewelry collection for a complete gift.
