Six clean edges, one shape-shifting stone. The hexagon at the heart of this alexandrite ring is a genuine color-shift gem — teal and blue-green by daylight, then a deep purple-violet under warm indoor light. The geometric cut catches the light from every facet, so the change is easy to see. Set in solid 925 sterling silver with a rhodium finish and framed by cubic zirconia accents, it is a fantasy-inspired design with a modern, architectural edge.

A geometric take on a magical stone
The hexagon cut is where Art Deco geometry meets a little fantasy. Its straight, faceted sides give the alexandrite a crisp, contemporary silhouette that stands apart from the usual round or oval, while the slim comfort-fit band keeps everything light on the finger. It reads equally as an engagement ring, a promise ring, or a striking everyday statement.

The lab-grown alexandrite
The center is a genuine lab-grown alexandrite, a 7mm hexagon of roughly 1.2 carats. It is the same chrysoberyl mineral as natural alexandrite, grown in controlled conditions so it carries the exact chromium chemistry responsible for the color change — only cleaner, brighter and far more affordable than a mined stone of the same size. If you want to understand the trade-offs, our guide to lab-grown versus natural alexandrite is a clear starting point, and our note on whether synthetic alexandrite changes color explains why the effect is completely real.
Cubic zirconia accents
Petite simulated diamonds border the hexagon, adding a bright ribbon of sparkle that plays off the shifting center. The cubic zirconia is precision-cut for crisp fire and keeps the design delicate and lightweight. Prefer moissanite or lab-grown diamond accents? Message us and we can build the ring to order.
Solid sterling silver with a rhodium finish
Crafted in solid 925 sterling silver, the ring is finished with rhodium — the same bright metal used on fine white gold. That rhodium plating gives a mirror-white luster and a protective layer that resists tarnish and everyday scratches, so the silver keeps its just-polished glow. The band is nickel-free and hypoallergenic, comfortable for sensitive skin and daily wear alike.
What the alexandrite symbolizes
Alexandrite’s twin colors have long stood for balance, transformation and a love that adapts to whatever the day brings — which is why it resonates as an engagement or milestone gift. It is also one of June’s birthstones, making the hexagon a thoughtful nod to a summer birthday. Torn between this and a classic blue gem? Our comparison of alexandrite versus sapphire weighs both, and the hexagon stacks handsomely with pieces from our alexandrite wedding bands.

Frequently asked questions
Does the alexandrite really change color?
Yes. The faceted hexagon is openly set so the shift is easy to see — teal and blue-green in daylight, warming to purple-violet under lamplight or candlelight. It is one of the most striking things about the ring.
Why does alexandrite shift color?
Trace chromium in the stone absorbs light differently under different sources. Blue-rich daylight makes it look green; red-rich warm light makes it look purple. It is a genuine optical property of alexandrite, not a treatment or coating.
Is the alexandrite genuine?
Yes, it is 100% genuine lab-grown alexandrite, chemically identical to mined alexandrite but ethically created and far more attainable. Only the small accent stones are cubic zirconia.
Why choose a hexagon cut?
The hexagon gives a clean, geometric, Art Deco look that stands out from round and oval stones. Its straight edges and facets also do a lovely job of showing off the alexandrite color shift.
What are the accent stones?
They are simulated diamonds (cubic zirconia), precision-cut for bright, crisp sparkle around the center. If you would prefer moissanite or lab-grown diamond accents, contact us and we can make it to order.
What metal is the ring made from?
Solid 925 sterling silver, finished with rhodium for a bright white luster and extra protection against tarnish and scratches.
What does the rhodium finish do?
Rhodium is the same precious metal used on fine white gold. It gives the silver a mirror-bright shine and adds a protective layer that keeps the ring looking freshly polished.
Is it hypoallergenic?
Yes. The band is solid 925 sterling silver, nickel-free and hypoallergenic, with a rhodium finish — comfortable for sensitive skin and suited to everyday wear.
Is it durable enough for daily wear?
Yes. Alexandrite sits around 8.5 on the Mohs scale, which makes it well suited to daily wear with normal care. Avoid hard knocks and remove the ring for rough activities to keep it pristine.
Can it be engraved?
Yes. You can add a personal engraving of up to 16 characters at checkout — a date, initials or a short message. Engraved pieces are final sale, so please double-check spelling.
What size should I order?
Select your ring size at checkout. If you are unsure or between sizes, contact us for guidance. Resizing is available and starts from a modest fee.
Is alexandrite a June birthstone?
Yes. Alexandrite is one of the celebrated birthstones for June, which makes this hexagon ring a thoughtful gift for a June birthday, an engagement or an anniversary.
Does it arrive gift-ready?
Every order ships in a free luxury velvet gift box and is backed by our lifetime warranty — ready to give or to keep for yourself.
