One clean triangle, endless moods. This triangle cut alexandrite ring centers a single color-changing lab-grown alexandrite that reads fresh green in daylight and deepens to purplish-blue in the glow of a lamp or candle. A dainty 1.6 mm band in warm 14K rose gold vermeil keeps the look modern and minimalist — a color-changing engagement or promise ring for someone who likes their jewelry a little unexpected.

A triangle cut with attitude
The triangle cut is bold without being loud. Its three crisp points catch the light from angles a round or oval never could, giving this otherwise minimalist ring a geometric, slightly avant-garde edge. Set on a slim solitaire band, the stone floats front and center with nothing to distract from it. It is a design made for anyone drawn to unique engagement rings and the modern end of our nature-inspired engagement rings.
The color-changing alexandrite
Alexandrite earns its reputation the moment the light shifts. In daylight the triangle glows a captivating green, reminiscent of fresh spring foliage; step under incandescent or candlelight and it transforms to a rich purplish-blue, like the last color of a sunset. Ours is a genuine lab-grown alexandrite, cultivated to capture that rare, dramatic color change with vivid saturation and clean clarity. Want to know exactly how the phenomenon works? Our explainer on whether synthetic alexandrite changes color breaks it down, and lab-grown vs natural alexandrite covers what shoppers really need to know.
Real gold over sterling silver
The ring is crafted in 14K rose gold vermeil — real rose gold layered over sterling silver 925 — so you get the warm, rosy glow of gold and a quality feel at a price that stays approachable. The petite 1.6 mm band is lightweight and comfortable, made to be worn every day and stacked with other pieces from our alexandrite jewelry collection. A matching band is available separately if you would like to build the look.
What alexandrite symbolizes
A June birthstone, alexandrite is a symbol of transformation, balance and good fortune — a fitting emblem for new chapters and evolving love. Because it changes with its surroundings yet remains unmistakably itself, many couples see their own story in it. If you are comparing gemstones, our piece on alexandrite vs sapphire weighs which feels more one-of-a-kind, and you can see more color-shifting styles in our alexandrite engagement rings collection.

Frequently asked questions
Does the alexandrite really change color?
Yes. The lab-grown alexandrite reads fresh green in daylight and shifts to a rich purplish-blue under incandescent or candlelight. The change is clearly visible as you move between light sources.
Is the alexandrite natural or lab-grown?
It is a genuine lab-grown alexandrite. Natural alexandrite is extraordinarily rare, so lab-grown delivers the same striking color change and clarity at a much more accessible price.
Why choose a triangle cut?
The triangle cut is modern and geometric, with three crisp points that catch light from unexpected angles. It gives a minimalist solitaire a bolder, more distinctive personality.
What is rose gold vermeil?
Rose gold vermeil is real 14K rose gold layered over sterling silver 925. You get the warm, rich look of rose gold at an easier price than solid gold. If you would like gold all the way through, the same design is also available in solid gold.
Is there a matching band?
Yes. A matching band is available separately, so you can wear this ring on its own or pair it with a band to complete the stacked look.
Is this ring good for daily wear?
Yes. Alexandrite is hard and durable at around 8.5 on the Mohs scale. With everyday care and by removing it for rough activities, showering and swimming, it holds up beautifully.
Can it be used as an engagement or promise ring?
Definitely. Its clean solitaire silhouette and meaningful color-changing stone make it a favorite for engagements, promises and anniversaries.
How wide is the band?
The band is a dainty 1.6 mm on average, keeping the ring light and comfortable while letting the triangle-cut center take the spotlight.
Can it be engraved?
Yes. You can add a personal engraving of up to 16 characters at checkout, such as a date or initials. Engraved pieces are final sale, so please double-check the 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.
Are the stones ethically sourced?
