Big, bold, and impossible to pin down to one color. This 3 ct princess cut alexandrite engagement ring leads with a square-cut color-changing center that reads deep teal and blue-green in daylight, then swings to rich violet and purple-red under indoor and candlelight. The alexandrite is faceted and set in the open, so the shift is on full display — a substantial, sharp-cornered stone in 925 sterling silver with a rhodium finish, built to make a statement every time the light moves.

A bold princess-cut statement
The princess cut is all crisp geometry — a square outline with sharp corners and brilliant faceting that fires light from edge to edge. At a generous 3 ct and 8 x 8 mm, this center commands the hand with clean, modern presence, the kind of stone that reads as confident rather than fussy. It anchors a bold end of our alexandrite engagement rings, and it looks striking stacked with a matching band from our alexandrite couples rings.
The color-shift, magnified
A bigger stone means a bigger stage for alexandrite’s signature trick. Trace chromium in the crystal absorbs yellow-orange light, so under blue-rich daylight or fluorescent light the princess cut reads teal and blue-green, while under red-rich incandescent bulbs or candlelight the same stone reads violet and purple-red. Because it is faceted and open-set rather than sealed in resin, the shift is genuinely visible — and across 3 ct of surface, it is hard to miss. See how faithfully a created stone reproduces it in our journal on whether synthetic alexandrite changes color.
The lab-created alexandrite center
The 3 ct princess cut is lab-created alexandrite — the same chromium-traced chrysoberyl as mined alexandrite, matching it in composition, 8.5 Mohs hardness and color-changing optics, grown in a lab rather than mined. A 3 ct natural alexandrite would be extraordinarily rare and cost a small fortune, so a lab-created center is the only way to wear this much color-shift at an approachable price. Our guide to lab-grown vs natural alexandrite lays out what that means for you.
Simulated diamond accents
Simulated diamond (CZ) accents flank the center, adding a crisp band of white sparkle that frames the princess cut and makes its shifting color read even more vividly against the bright fire. It is a clean, brilliant complement that keeps the ring accessible while looking every inch a statement piece. Prefer moissanite or natural-diamond accents? Message us and we can build it to order.
Solid sterling silver with a rhodium finish
The ring is crafted in solid 925 sterling silver with a rhodium finish — the same white metal used on fine white gold. The finish delivers a bright, mirror-white luster and a protective layer against tarnish and everyday scratches, so a big-stone silver ring keeps its polish. It is also nickel-free and hypoallergenic, easy on sensitive skin, and its cool white tone lets the alexandrite’s colors read at full strength.
What alexandrite symbolizes
A stone that transforms with the light is a striking emblem for a love that keeps revealing new sides — alexandrite has long been tied to transformation, balance and the harmony of opposites. As one of the three traditional June birthstones, this ring also makes a bold June birthday gift. Choosing between alexandrite and another blue-violet gem? Our comparison of alexandrite vs sapphire explains why the color-change sets it apart.

Sizing & care
Choose your size at checkout; if you’re between sizes or unsure, contact us and we’ll guide you. Resizing is available and starts from a modest fee. To keep the color-shift vivid and the rhodium bright, remove the ring before showering, swimming or applying lotions, store it in its box, and buff gently with a soft dry cloth. At 8.5 Mohs the alexandrite is hard enough for confident daily wear — just protect the sharp corners of the princess cut from hard knocks.
Frequently asked questions
Does this ring really change color?
Yes. The 3 ct princess-cut alexandrite reads deep teal and blue-green in daylight and shifts to violet and purple-red under warm incandescent or candlelight. It is faceted and open-set, so across its large surface the color-shift is easy to see as your lighting changes.
Why does alexandrite change color?
Trace chromium in the crystal absorbs yellow-orange light. Blue-rich daylight leaves the stone reading teal-blue-green; red-rich indoor light leaves it reading violet. It is the same optical effect in natural and lab-created alexandrite.
Is the alexandrite genuine?
Yes — it is real lab-created alexandrite, identical to mined alexandrite in composition, 8.5 Mohs hardness and color-changing optics. It was grown in a lab rather than mined, which is the only difference.
Is a 3 ct alexandrite natural?
This is a lab-created 3 ct stone. A natural alexandrite this large would be exceptionally rare and cost a small fortune, so a lab-created center is what makes a bold 3 ct color-changer wearable at this price — with the identical color-shift and hardness.
What is a princess cut?
A princess cut is a square-outlined stone with sharp corners and brilliant faceting that fires light across its whole surface. It reads modern and confident, and the large flat table gives alexandrite plenty of room to show its color-shift.
What are the accent stones?
Simulated diamonds (CZ) that add a crisp band of white sparkle framing the center and making the alexandrite’s color read more vividly. If you’d prefer moissanite or natural-diamond accents, contact us to build it to order.
What metal is it made from?
Solid 925 sterling silver finished with rhodium, the same white metal used on fine white gold, for a bright luster and added protection.
What does the rhodium finish do?
Rhodium gives the silver a mirror-white, white-gold-like shine and a protective layer that helps resist tarnish and scratches, keeping the ring looking freshly polished.
Is it good for sensitive skin?
Yes. The ring is nickel-free and hypoallergenic in both 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 it is one of the hardest colored gems used in engagement rings. With a princess cut, just take care to protect the sharp corners from hard knocks, and it wears well every day.
Is alexandrite a June birthstone?
Yes — it is one of the three traditional June birthstones, so this ring makes a bold June birthday gift as well as an engagement or promise ring.
Can it be resized?
Yes, within reason by a jeweler. Resizing is available and starts from a modest fee. Order your correct size from the start where possible.
Are the stones ethically sourced?
Yes. All of our stones are ethically sourced and conflict-free, so you can wear this ring with complete peace of mind.
Does it arrive gift-ready?
Every order ships in a free gift-ready ring box with a lifetime warranty. It also pairs beautifully with pieces from our alexandrite jewelry collection.
