Aurora Alexandrite Ring - Sterling Silver

Step outside and the center stone reads cool teal-blue. Step back under a lamp and it warms to violet-purple. That shift is the whole point of the Aurora — a lab alexandrite engagement ring built around a 1.4 ct oval that behaves differently in every room you walk into, cradled in a vintage-inspired halo of simulated diamonds on solid 925 sterling silver.

The color shift is the feature

Most gemstones have one color. Alexandrite has a temperament. Under daylight and cool white LEDs the oval sits in the teal-to-blue end of its range; under incandescent bulbs, candlelight, and low evening light it swings toward purple. Nothing about the stone changes — what changes is which part of the spectrum is available for it to reflect, and alexandrite is unusually sensitive to that. It is the reason people who find diamonds a little static fall hard for this stone.

The practical version: your ring will not look the same in your kitchen as it does on a restaurant patio, and photographs of it will genuinely disagree with each other. If you want to understand why before you buy, our guide to how synthetic alexandrite changes color walks through the mechanism in plain language.

Lab-grown, and honest about it

This center stone is lab-grown alexandrite. Natural alexandrite is one of the rarest gemstones on earth — a clean one-carat natural stone outprices most diamonds of the same size, which is why almost nobody wears one. Lab growth produces the same chrysoberyl chemistry and the same color-change behavior at a price that puts the stone on an actual hand instead of in a vault. We say lab-grown plainly because it is the honest description, and because it is the reason this ring exists. For the full comparison, see lab-grown vs natural alexandrite.

At 8.5 on the Mohs scale, alexandrite is one of the harder colored stones you can put in a ring — harder than emerald, harder than tanzanite, sitting just below sapphire. That matters more for everyday wear than any certificate does.

A vintage halo, sized to be noticed

The oval center measures 7.0 x 9.0 mm and is ringed by a halo of simulated diamonds, giving the head an overall footprint of 17.5 x 13.1 mm. The halo does two jobs: it throws white sparkle around a stone whose own color is soft and shifting, and it visually enlarges the center without the cost of a larger alexandrite. The band tapers to an average 2.1 mm, which keeps the profile elegant rather than heavy and lets the ring sit flush against a wedding band later.

Solid 925 sterling silver with a rhodium finish

The setting is solid 925 sterling silver, finished with rhodium for a brighter white luster and an added layer of protection over the silver beneath. That bright white is deliberate: it reads cool against the teal phase of the stone and keeps the purple phase from turning muddy, which is exactly what a warm yellow metal would do. It is also 100% nickel-free and hypoallergenic, with a comfort-fit interior. If sterling is new to you, what 925 sterling silver actually means is a five-minute read.

June’s modern birthstone

Alexandrite is one of June’s birthstones, alongside pearl and moonstone — the modern addition, and by far the most dramatic of the three. That makes this ring a natural June birthday gift, but the color-shift symbolism travels well beyond birthdays: two faces of one stone reads convincingly as a promise ring, an anniversary piece, or an engagement ring for someone who was never going to say yes to a plain solitaire. Our June birthstone guide covers the full trio, and the alexandrite engagement rings collection shows the rest of the family.

Sizing & care

Choose your size from the dropdown above. If you are between sizes or measuring for a surprise, our ring sizing guide walks through the two reliable ways to do it at home.

Care is simple. Take the ring off before swimming, cleaning, or applying lotion and perfume, and put it on last when you get dressed. Clean it with warm water, a drop of mild dish soap, and a soft toothbrush around the halo where dust collects, then dry it fully with a soft cloth. Store it in the ring box rather than loose in a drawer. Skip ultrasonic cleaners and steamers. Our guide to cleaning sterling silver at home has the longer version.
