A frame of light around a stone that refuses to stay one color. At the heart of this radiant cut halo alexandrite ring sits a faceted ~2 ct lab-grown alexandrite that reads teal, blue and green in daylight and shifts to purple and violet under warm indoor light — a genuine color-change, set in the open so it is never hidden. A full pave halo and a pave-set band wrap it in bright sparkle, all in 925 sterling silver with a rhodium finish, for a vintage-halo look with living color at its center.

A vintage halo, wall to wall in sparkle
A full pave halo wraps the entire perimeter of the radiant center, and the sparkle continues down both shoulders in a continuous pave band, so the ring reads as one unbroken ribbon of light leading to the stone. It is a deliberately heritage-inspired, vintage-halo construction — substantial bridal presence without heaviness. This is one of the more decorative pieces in our alexandrite engagement rings, and it stacks beautifully with a plain or pave band from our alexandrite couples rings.
The color-shift at the center
Alexandrite is prized above all for its color-change, and a halo of bright white pave only makes it more dramatic by contrast. Trace chromium in the crystal absorbs yellow-orange light, so under blue-rich daylight or fluorescent light the radiant center reads teal, blue and green, while under red-rich incandescent or candlelight it shifts to purple and violet. The stone is faceted and open-set — not resin-set or crushed — so the shift is fully visible as you move through the day. Our journal on whether synthetic alexandrite changes color explains just how faithfully a created stone reproduces it.
The lab-grown alexandrite center
The 6 x 8 mm radiant (about 2 ct) is genuine lab-grown alexandrite — the same chromium-traced chrysoberyl as mined alexandrite, matching its 8.5–9 Mohs hardness and color-changing optics, created in a lab rather than mined. Natural alexandrite of this size is one of the world’s rarest and most expensive gems, so a lab-grown center is what makes a 2 ct color-changer wearable at fine-jewelry pricing. Our guide to lab-grown vs natural alexandrite covers what shoppers should know.
The radiant cut and pave accents
The radiant cut pairs the elongated outline of an emerald cut with the brilliant faceting of a round — a shape that maximizes light return and color play, ideal for showing off alexandrite’s shifting hues. The halo and band are set with simulated diamond (CZ), a crisp, brilliant accent that frames the center and amplifies its color against bright white fire. Prefer moissanite or natural-diamond accents, or a solid-gold build? Message us before ordering and we can create 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 gives a bright, mirror-white luster and a protective layer against tarnish and everyday scratches, keeping the pave crisp and the silver freshly polished. It is nickel-free and comfort-fit inside, and the cool white tone lets the alexandrite’s colors read at full saturation.
What alexandrite symbolizes
A stone that transforms with the light is a fitting emblem for a love that adapts and reveals new facets over time — alexandrite has long been associated with transformation, balance and the harmony of opposites. First found in Russia’s Ural Mountains in the 1830s and one of the three traditional June birthstones, it also makes a meaningful June birthday and 55th-anniversary gift. Deciding between it and another blue-violet gem? Our comparison of alexandrite vs sapphire explains why the color-change makes it feel one of a kind.

Sizing & care
Choose your size at checkout; if you’re between sizes or unsure, contact us for guidance. Resizing is available and starts from a modest fee, though a halo and pave setting is best resized by a skilled jeweler to protect the stones. To keep the color-shift vivid and the rhodium bright, remove the ring before showering, swimming or applying lotions, store it separately in its box, and clean gently with a soft brush and warm soapy water, avoiding harsh or ultrasonic cleaners. At 8.5–9 Mohs the alexandrite is exceptionally suited to everyday wear.
Frequently asked questions
Does this ring really change color?
Yes. The lab-grown alexandrite center reads teal, blue and green in daylight and shifts to purple and violet under warm incandescent or candlelight. Because the stone is faceted and open-set rather than resin-set, the color-shift is fully visible as your lighting changes.
Why does alexandrite change color?
Trace chromium in the crystal absorbs yellow-orange light. Under blue-rich daylight the stone reads teal-blue-green; under red-rich indoor light it reads purple-violet. It is the same effect in natural and lab-grown alexandrite.
Is the alexandrite real?
Yes — it is genuine lab-grown alexandrite, identical to mined alexandrite in composition, 8.5–9 Mohs hardness and color-changing optics. It was created in a lab rather than mined, which is the only difference.
Why lab-grown instead of natural?
Natural alexandrite of this size is among the most expensive gems in the world. A lab-grown center delivers the identical color-shift, brilliance and hardness at fine-jewelry pricing, which is what makes a 2 ct color-changer like this attainable.
What is a radiant cut?
A radiant cut combines the elongated outline of an emerald cut with the brilliant faceting of a round. It maximizes light return and color play, making it especially good at showing off alexandrite’s shifting hues.
How dramatic is the color-shift?
It is genuinely visible — most striking when you compare the stone in two different lights, such as daylight versus a warm indoor bulb. Warm incandescent and candlelight push the most purple; daylight and fluorescent light push the most teal-green. The bright pave halo makes the contrast even easier to see.
What are the halo and band stones?
The full pave halo and band are set with simulated diamond (CZ) — a crisp, brilliant accent that frames the center and amplifies its color. If you’d prefer moissanite or natural-diamond accents, or a solid-gold build, contact us to create 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 pave crisp and the ring freshly polished.
Is it nickel-free?
Yes. The ring is nickel-free in both the sterling silver base and the rhodium finish, and it has a comfort-fit interior, so it is easy to wear for sensitive skin.
Is alexandrite durable enough for daily wear?
Yes. At 8.5–9 on the Mohs scale it is one of the hardest colored gems used in engagement rings, just below sapphire and ruby, so it stands up well to everyday wear with normal care.
Is alexandrite a June birthstone?
Yes — it is one of the three traditional June birthstones and the traditional 55th-anniversary gemstone, so this ring makes a meaningful birthday or anniversary gift as well as an engagement ring.
Can a halo ring be resized?
Yes, within reason. A halo and pave setting is best resized by a skilled jeweler to protect the stones. Resizing is available and starts from a modest fee; order your correct size from the start where possible.
Does it arrive gift-ready?
Every order ships in a free ring box with a lifetime warranty and free US shipping. It also pairs beautifully with pieces from our alexandrite jewelry collection.
