One ring, two moods. The lab-grown alexandrite at the heart of this hexagon halo ring shifts from cool teal-blue in daylight to a warm purplish-red under lamplight and candle glow — a genuine color change you can watch happen on your own hand. Set in a crisp geometric hexagon halo of simulated diamonds and wrapped in warm 14K rose gold vermeil, it is a bold, modern alternative engagement ring for anyone who wants a stone with a little magic in it.

Architectural geometry, softened in rose gold
The hexagon halo gives this ring its signature look — six clean facets of simulated diamonds framing the round center like a piece of fine Art Deco architecture. It is precise without feeling cold, thanks to the warm blush of the rose gold vermeil that ties the whole design together. If you are drawn to geometry over the traditional round solitaire, you will find kindred pieces across our kite-cut alexandrite engagement rings and the wider world of nature-inspired engagement rings.
The color-change alexandrite
Alexandrite is famous for one thing above all: it changes color. Our center stone is lab-grown, which means it delivers that mesmerizing shift vividly and consistently — blue-green in cool daylight, glowing purple-red under warm indoor light. Lab-grown alexandrite is the same material grown in controlled conditions, so you get the drama of one of the world's rarest optical effects without the rarity price. Curious how the effect actually works? Our guide on whether synthetic alexandrite changes color explains it beautifully, and lab-grown versus natural alexandrite covers what shoppers really need to know.
A halo of simulated diamonds
Six bright simulated diamonds ring the center in a hexagon frame, catching the light from every angle and making the color-shift stone read even larger. Simulated diamonds give you crisp, brilliant sparkle at a friendly price — the perfect supporting cast for a center stone that already does something extraordinary. Together they make a ring that photographs as beautifully as it wears.
Rose gold vermeil
This ring is crafted in 14K rose gold vermeil — a rich layer of real 14K rose gold over a solid base of sterling silver 925. That warm, rosy tone flatters every skin tone and makes the cool-to-warm color play of the alexandrite feel even more alive. It is the golden look you love at a price that lets you say yes today.

What alexandrite symbolizes
As the birthstone of June, alexandrite has long stood for transformation, balance and good fortune — a fitting emblem for a relationship that grows and changes together. Its dual nature, one stone showing two faces, makes it a romantic choice for couples who value depth over the obvious. If you are weighing it against another jewel-toned classic, our comparison of alexandrite versus sapphire is a lovely read, and you can see the full range in our alexandrite engagement rings collection.

Frequently asked questions
Does the alexandrite really change color?
Yes. The center stone shifts from a cool teal-blue in daylight to a warm purplish-red under lamplight or candle glow. It is the signature effect alexandrite is prized for, and it is clearly visible in this open setting.
Is the alexandrite lab-grown?
Yes. The center is a lab-grown alexandrite, which delivers the color change vividly and consistently. It is the same material as its rare mined counterpart, grown in controlled conditions so the effect is bright and dependable.
What is rose gold vermeil?
Rose gold vermeil is real gold over sterling silver 925 — the warm, golden look of gold at an easier price. If you would like gold all the way through, the same design is also available in solid gold.
What shape and size is the center stone?
It is a 6.0 mm round brilliant, roughly 0.85 carat, set inside a hexagon halo that measures about 10.5 mm across, so the ring reads larger than the center alone.
What are the accent stones?
The halo is set with simulated diamonds, which add crisp, brilliant white sparkle around the color-change center at a friendly price.
Is it durable enough for everyday wear?
Alexandrite sits at 8.5 on the Mohs scale, which is excellent hardness for a ring worn regularly. With normal care it is well suited to daily life.
Can this be an engagement ring?
Absolutely. Its bold hexagon halo and rare color-change stone make it a striking alternative engagement ring, and it works equally well as a promise ring or June birthstone gift.
Can I have it 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.
How do I care for it?
Remove it before showering, swimming or exercise, keep it away from lotions and fragrance, and store it dry in the velvet box between wears. Buff gently with a soft dry cloth to restore shine.
