Architecture for a stone that refuses to sit still. The Elongated Cushion Halo Alexandrite Ring centers a roughly 3 ct color-changing alexandrite in a sparkling halo, set on a twisted rope band. In daylight the cushion glows blue to violet; under warm indoor light it turns purple to soft red. Crafted in 14K rose gold vermeil, it is a bold, structured take on a gemstone that is anything but ordinary.

A defined, elongated silhouette
The elongated cushion cut gives this ring a long, elegant footprint on the finger, while the surrounding halo of pave sparkle makes the center appear even larger and pulls in light from every direction. A twisted rope band adds texture and grip, so the whole design reads architectural rather than dainty. It is a statement piece for anyone who wants presence, and it sits alongside the best of our alexandrite engagement rings.
The color-change in the spotlight
Alexandrite earns its reputation here. Under daylight the cushion reads cool blue to violet; move into warm incandescent light or candlelight and it shifts toward purple and reddish tones. The halo frames that transformation so it never gets lost. If you love the phenomenon and want to know how it works, our guide on how synthetic alexandrite changes color is a great read, and you can find more shifting stones across our alexandrite jewelry range.
Real, lab-grown alexandrite
The center is genuine lab-grown alexandrite: the same chrysoberyl mineral as natural alexandrite, grown in a lab so the color-change is vivid, consistent and affordable, since mined alexandrite of this size would be extraordinarily rare. At 8.5 to 9 on the Mohs scale it is impressively hard-wearing for daily life. To understand the difference between lab-grown and mined, see our honest guide to lab-grown vs natural alexandrite.
A halo of brilliant accents
Cubic zirconia forms the halo and lines the twisted band, wrapping the center in a continuous ring of crisp white sparkle. It is a bright, budget-friendly way to maximize brilliance and make the alexandrite look even bigger and more luminous. If you are choosing between vivid gemstones, our comparison of alexandrite vs sapphire lays out what makes each one special, and you will find more unusual center stones in our unique engagement rings collection.

Frequently asked questions
Does the alexandrite really change color?
Yes. In daylight the cushion reads blue to violet, and under warm indoor light it shifts toward purple and reddish tones. The color-change is a real, visible feature, with intensity varying by light source and environment.
Is the alexandrite real?
It is genuine lab-grown alexandrite, the same chrysoberyl as mined alexandrite, grown in a lab for a vivid, dependable color-change. Natural alexandrite of this size is extraordinarily rare, so lab-grown is the standard for alexandrite rings.
What is rose gold vermeil?
Rose gold vermeil is real gold layered over sterling silver 925, so you get the warm, golden look of rose gold at a much easier price. If you would prefer gold all the way through, the same design is also available in solid gold.
How big is the center stone?
The elongated cushion measures 7.0 x 9.0 mm, approximately 3 ct, and the surrounding halo makes it look even larger on the hand.
What is the halo made of?
Cubic zirconia forms the halo and runs along the twisted band, adding a crisp, continuous ring of white sparkle. It is a bright, budget-friendly way to amplify the center stone.
What is the band like?
A twisted rope design about 2.1 mm wide, which adds texture and contrast against the smooth halo and gives the ring an architectural, substantial feel.
Is alexandrite durable enough for daily wear?
Yes. Alexandrite sits at 8.5 to 9 on the Mohs scale, among the harder gemstones, making it well suited to everyday wear with normal care.
What metal is the ring made from?
14K rose gold vermeil: a genuine layer of 14K rose gold over a solid sterling silver 925 base, giving the ring its warm blush tone.
Can the ring be engraved?
Yes. You can add a personal engraving of up to 16 characters at checkout. Engraved pieces are final sale, so please double-check spelling.
How do I care for it?
Remove it before showering, swimming or exercise, avoid contact with lotions and fragrance, and store it dry in the velvet box between wears. A soft, dry cloth restores its shine.
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.

Yes. Our stones are ethically sourced and conflict-free, and lab-grown alexandrite is an inherently responsible choice.
