One stone, two moods. The oval alexandrite at the heart of the Valentina vintage-inspired engagement ring shifts from cool teal in daylight to warm violet-purple under evening light — a visible, living color-change framed by an Art Deco setting of milgrain detail and simulated diamonds, all cast in 14K rose gold vermeil.

A color-change you can watch happen
The reason people fall for alexandrite is simple: it changes color with the light. This oval center glows teal to blue-green in natural daylight, then turns violet-purple under lamps and candlelight. The effect is real and easy to see — move your hand from a sunny window to a warm room and the whole stone transforms. It is the closest thing to magic you can wear on your finger. Our article on how synthetic alexandrite changes color breaks down the phenomenon in plain language.
A genuine lab-grown alexandrite
Natural alexandrite is one of the rarest gems on earth, which is why this center is a genuine lab-grown alexandrite — identical in optics and color-change, grown so the shift is bright and dependable. It is the ethical, attainable way to own a stone that would otherwise be almost impossible to find. If you want the full picture, our guide to lab-grown versus natural alexandrite is worth a read.
Art Deco romance, milgrain and all
The setting is pure vintage theatre: geometric Art Deco lines, delicate milgrain beading along the edges, and a frame of sparkling simulated diamonds (CZ) that lifts the center stone with crisp, brilliant light. Worn alone it is a statement; paired with matching milgrain bands it becomes a full stacked look. It sits beautifully within our alexandrite jewelry and pairs naturally with our alexandrite wedding bands.
Rose gold vermeil over sterling silver 925
Valentina is crafted in 14K rose gold vermeil — real rose gold over a core of sterling silver 925. The warm, rosy tone is a perfect foil for the alexandrite’s cool-to-warm shift, and it brings a heirloom-inspired design within easy reach.

Frequently asked questions
Does the alexandrite actually change color?
Yes, and it is clearly visible. The oval center reads teal to blue-green in daylight and turns violet-purple under lamplight and candlelight. Watching it shift as you move between light sources is the whole joy of the stone.
Is the alexandrite genuine?
It is a genuine lab-grown alexandrite — the same optical properties and dramatic color-change as the natural gem, grown in controlled conditions for a bright, consistent shift. Natural alexandrite is exceptionally rare, so this is the ethical, attainable way to own one.
What colors should I expect?
Teal to blue-green in natural daylight, and purple to violet under warm indoor and evening light. The exact tone depends on your surroundings, which is part of what makes each moment feel unique.
What is rose gold vermeil?
Rose gold vermeil is real 14K rose gold layered over sterling silver 925. It gives you the warm, rich look of rose gold at a far friendlier price than a solid-gold piece. If you would like gold all the way through, the same design is also available in solid gold.
What are the accent stones?
Sparkling simulated diamonds (cubic zirconia) frame the center in classic Art Deco style, adding crisp, brilliant light around the color-changing alexandrite.
Can I wear it with matching bands?
Yes. The Art Deco setting is designed to pair with one or two vintage-style milgrain bands for a full stacked look, or to be worn beautifully on its own.
Is it suitable for an engagement ring?
Very much so. Alexandrite is a hard 8.5 on the Mohs scale, and the vintage silhouette makes a distinctive, non-traditional engagement or promise ring for anyone who loves color and history.
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 its velvet box between wears. A soft, dry cloth restores the shine.
What size should I order?
The ring runs true to size, so order your usual size. If you are unsure or between sizes, contact us for guidance. Resizing is available and starts from a modest fee.
Does it arrive gift-ready?
Yes. Every order ships in a free luxury velvet gift box and is backed by our lifetime warranty — ideal for a proposal, anniversary or birthday.
Are the stones ethically sourced?
Yes. All of our stones are ethically sourced and conflict-free, so you can wear the ring with complete peace of mind.
Is this a good June birthstone gift?
Ideally. Alexandrite is a June birthstone, so the Valentina makes a heartfelt birthday, anniversary or promise gift for anyone born in June or drawn to color-changing gems.
