Catch it in morning daylight and it reads a cool teal-blue; carry it into candlelight and the same stone turns a deep purple-violet. That live color-shift is the whole point of this split-shank halo alexandrite engagement ring. The faceted princess-cut center sits open to the light in rhodium-finished 925 sterling silver, framed by a split-shank double halo that sets every flash of teal and violet dancing across your hand.
The color-change you can actually see
Alexandrite is prized for one rare talent: it appears to change color with the light around it. Because this center stone is a faceted, open-set princess cut rather than a sealed inlay, that shift is fully on display. Cool daylight and fluorescent light pull out a vivid teal-to-blue; warm incandescent or candlelit rooms deepen it to purple-violet. It is a single stone revealing two moods, which is exactly why alexandrite has become the modern emblem of a love that adapts and endures. If you want to understand the science behind the effect, our guide on whether synthetic alexandrite changes colors walks through it in plain language. You will find the whole family of shifting stones in our alexandrite engagement rings collection.
An honest note on the stones
The center is lab-grown alexandrite — a genuine alexandrite gemstone created in controlled conditions rather than mined, with the same optical color-change and hardness as its natural counterpart, plus a consistent, conflict-free origin. The surrounding accents are simulated diamonds, chosen for their crisp white sparkle and brilliant value against the color-shifting center. If you are weighing your options, our explainer on lab-grown versus natural alexandrite covers what actually matters. Prefer real stones in the halo? We can build this same design with lab-grown diamond or moissanite accents — just reach out before ordering.
The princess cut
The princess cut is a square, sharp-cornered shape with a brilliant facet pattern engineered for maximum fire and light return. On a color-change gem it does something special: the geometry catches and splits the light so you can see flashes of both teal and violet at once across the table. At 6.0 x 6.0 mm and roughly 1.0 carat, the center holds genuine presence on the hand without overwhelming a slender finger.
The split-shank double halo
This is where the design earns its sparkle. A split shank divides the band into two slim rows as it approaches the center, opening a graceful negative space on each side that lifts the alexandrite visually. Both rows are lined with pave simulated diamonds, and a double halo of micro-set stones squares off and frames the princess-cut center. The result reads far larger and more luminous than the carat weight alone. Loved as a pairing piece, it sits beautifully alongside styles from our alexandrite couples rings range.
Sterling silver with a rhodium finish
The ring is crafted in solid 925 sterling silver and finished with rhodium — the same bright precious-metal plating used on fine white gold. That rhodium finish gives a crisp, mirror-white luster that flatters the cool flashes in the alexandrite and adds a protective shield against everyday tarnish and scratches. The band is nickel-free and hypoallergenic, and genuine rhodium-finished sterling silver will not turn your skin green.
What alexandrite symbolizes
As one of June’s birthstones, alexandrite carries a long association with balance, intuition and transformation — the idea that love, like the stone, reveals new depth in different light. That sentiment makes it a meaningful choice for engagements, milestone anniversaries and promise rings alike. Curious how it compares to other colored-stone classics? Our piece on alexandrite versus sapphire is a helpful read, and you can browse more shifting pieces in our alexandrite jewelry collection.

Sizing & care
Choose your size at checkout. If you are between sizes or unsure, we are glad to help, and if the fit is not quite right, resizing is available and starts from a modest fee. To keep the color-change vivid and the halo sparkling, clean gently with warm water, a drop of mild soap and a soft brush, then dry with a lint-free cloth. Store it separately to protect the rhodium finish, and remove it before swimming, harsh chemicals or heavy manual work. With basic care, this is a ring made to be worn every day.
Frequently asked questions
Does this alexandrite really change color?
Yes. The faceted, open-set center visibly shifts from a cool teal-blue in daylight or fluorescent light to a deep purple-violet under warm, incandescent or candlelit light. It is one stone showing two moods depending on your surroundings.
Is the alexandrite real or lab-grown?
It is a real alexandrite gemstone that is lab-grown rather than mined. It has the genuine optical color-change and hardness of alexandrite, with consistent quality and an ethical, conflict-free origin.
What are the sparkling accent stones?
The halo and split-shank accents are simulated diamonds, selected for their bright white sparkle and value. If you would prefer real stones, we can build this design with lab-grown diamond or moissanite accents — just contact us before ordering.
What is a split-shank setting?
A split shank is a band that divides into two slim rows as it nears the center stone, creating an open negative space on each side. Here both rows are pave set and lead into a double halo, lifting the alexandrite and adding extra sparkle and visual size.
Can I wear this as an engagement ring?
Absolutely. With an 8.5–9 Mohs center stone and a substantial halo design, it is well suited as an alexandrite engagement ring, promise ring or anniversary ring meant for everyday wear.
Is this a good June birthstone gift?
Yes. Alexandrite is one of June’s birthstones, making this an ideal gift for a June birthday, a June anniversary or anyone drawn to its symbolism of transformation and balance.
What metal is the ring made from?
It is crafted in solid 925 sterling silver with a rhodium finish — the same bright white plating used on white gold — for a crisp mirror shine that complements the stone’s cool flashes.
What does the rhodium finish do?
Rhodium gives the silver a mirror-bright, white-gold-like luster and adds a protective layer that helps resist everyday tarnish and scratches, keeping the ring looking freshly polished.
Will it turn my finger green?
No. Genuine sterling silver with a rhodium finish does not turn skin green; that reaction is linked to low-quality or fake metals. The ring is also nickel-free and hypoallergenic.
How durable is alexandrite?
Very durable. Alexandrite rates 8.5–9 on the Mohs hardness scale, just below sapphire and ruby, so it stands up well to daily wear with basic care.
What is the center stone size and carat weight?
The princess-cut center measures 6.0 x 6.0 mm and is approximately 1.0 carat, giving it real presence on the hand while remaining elegant on a slender finger.
How do I choose my ring size?
Select your size at checkout. If you are unsure or between sizes, contact us for guidance or have your finger measured by a local jeweler. Resizing is available and starts from a modest fee.
Does it arrive gift-ready?
Yes. Every ring ships in a free luxury velvet gift box and is backed by our lifetime warranty — ready for a proposal, birthday or anniversary.
