We’ve always believed that jewelry should stay with you.

Not just for a moment, but through everyday life — through the days you don’t think about it, and the ones you’ll remember later.

But for something to truly stay with you, it cannot stop at the product.
It also needs to be supported over time.

That’s why we offer lifetime service for every piece.

If parts wear down or need to be replaced, we’ll take care of it for you — you only cover a small shipping cost. And if you’re already placing another order, we’re happy to include it without any additional shipping.

Because in the end, this isn’t just about jewelry.

It’s about creating something you can keep, rely on, and continue wearing — without worry.

If you ever need us, we’re always here at hello@heiracle.com.

Petal Crown Lab-Grown Alexandrite Ring holds its stone in a sculpted crown basket, prongs curling like petals above tapered pavé shoulders with a gentle vintage air. Inside, the lab-grown alexandrite shifts with the hour—teal green in daylight, easing into rich plum under evening light.

The change is the charm, a small transformation you get to watch again with every sunset. Sterling silver, with a closed band, and light on the hand for effortless daily wear.

Stone: lab-grown alexandrite, approx. 1.35 ct, color-change from teal green to plum
Cut & size: Round cut, 6.5mm x 6.5mm (approx. 0.26" x 0.26")
Setting: 925 sterling silver with white gold (rhodium) plating, nickel-free
Band: closed band, made to your chosen size
Care: keep dry off-wear, wipe with a soft cloth

Every ring in this collection is set in solid 925 sterling silver, finished with white gold (rhodium) plating for a bright, durable surface — and it is nickel-free, so it stays gentle on sensitive skin.

The stone is genuine lab-grown alexandrite: chromium-bearing chrysoberyl with the same chemistry, the same 8.5 hardness, and the same color-change behavior as mined alexandrite — teal green in daylight, plum red under warm evening light.

A little care goes a long way: take your ring off before showers, pools, and workouts, keep it dry, and give it a quick wipe with a soft cloth after wear. Stored dry, the plating keeps its brightness for years — and if it ever dulls, our lifetime service covers re-plating support.

At the same time, we do not compromise on materials. We use solid 925 sterling silver and genuine lab-grown alexandrite because long-term wear, safety, and comfort should never be sacrificed.

We also believe that craftsmanship deserves respect. Behind every piece is real work — and we are committed to supporting skilled makers and ensuring they are paid fairly for what they create.

For us, pricing is not about being the cheapest. It is about being honest, sustainable, and worth keeping.

FAQ

Questions, answered.

Is the color change real?

Yes - and it is the whole point. Chromium inside the crystal absorbs different wavelengths under different light, so the same stone reads teal green in daylight and shifts to plum red under warm lamps or candlelight. It is not a coating or a filter; the change is a permanent property of the crystal itself.

Is lab-grown alexandrite real alexandrite?

Chemically, yes. Lab-grown alexandrite is chromium-bearing chrysoberyl - the same composition, the same 8.5 hardness, and the same color change as the mined stone. The only difference is that it grows in a controlled lab over weeks instead of underground over millennia, which is why it costs a fraction of mined alexandrite.

Is it safe for sensitive skin?

Yes. The setting is solid 925 sterling silver with white gold (rhodium) plating and contains no nickel, so it stays gentle on sensitive skin for all-day wear.

How do I care for my ring?

Treat it like fine jewelry: take it off before showers, swimming, and workouts, keep it dry, and wipe it with a soft cloth after wear. Store it separately so the stone does not rub against other pieces. If the plating ever dulls over the years, our lifetime service covers re-plating support.

Can I customize the stone or setting?

Yes. If you are dreaming of a different cut, carat, stone, or setting, we offer custom service - email hello@heiracle.com with your idea and we usually reply within one business day.

The Alexandrite Effect

One stone. Two lives.

Alexandrite is one of the rarest optical phenomena in gemology. The same crystal reads teal-green under daylight, then turns raspberry-purple under candlelight and warm indoor lamps. Nothing is coated, nothing is heated on demand — the change is written into the crystal itself.

By day — a quiet teal green.

Under sunlight or cool white light, chromium inside the crystal absorbs the warm wavelengths and lets the greens through. Understated enough for the office, a walk, an ordinary Tuesday.

By night — raspberry and violet.

When the light turns warm — dinner, candles, lamplight — the same stone shifts toward purple-red. The ring you wore all day arrives at the evening as something else entirely.

Emerald by day, ruby by night — that is how alexandrite has been described since it was first documented in the 1830s. Tap the light to watch yours change.
