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.

LuAG Titanium Flat Back Stud Earrings are made with 6mm lab-created LuAG gemstones, known for their bright yellow-green sparkle in natural light and vivid neon-green fluorescence under UV light.

Crafted with ASTM F136 implant-grade titanium flat back posts, these earrings are lightweight, hypoallergenic, waterproof, and designed for comfortable 24/7 wear, including sleeping, showering, and everyday stacking.

We use ASTM F136 implant-grade titanium, a material widely used for long-term body contact.

Many earrings may contain nickel or reactive metals, which can cause irritation, redness, or discomfort over time — especially for sensitive ears.

Titanium behaves differently. It is highly stable, lightweight, and far less reactive, making it a more reliable choice for everyday wear.

In simple terms, it is designed to feel easier on your skin, so you can wear your earrings longer without the usual concerns.

During certain Chinese holidays, fulfillment may experience slight delays due to nationwide closures.

If your order is affected, we will reach out within 24 hours after your purchase to inform you clearly and explain the timing.

These pauses are intentional. We believe in supporting the people behind the work — giving our team time to rest and be with their families. In China, moments of reunion are deeply valued, and we choose to honor that.

If you’re happy to keep your order during this time, we’ll make sure it’s worth the wait with a small surprise prepared for you.

Holiday notices will always be shared on our homepage in advance.

We believe in offering a fair and thoughtful price for what we make.

By working closer to the source and reducing unnecessary layers in the supply chain, we are able to keep our pricing more accessible without relying on excessive markups.

At the same time, we do not compromise on materials. We use ASTM F136 implant-grade titanium 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.

What is LuAG?

LuAG is a lab-created fluorescent gemstone originally used in advanced optical materials. In natural light, it shows a soft yellow-green sparkle, small in size but surprisingly distinctive.

Its glow comes from fluorescence, not harmful radiation. Because sunlight also contains UV rays, LuAG can reveal a vivid neon-green glow not only under a UV lamp, but also in everyday lighting moments. We use it in 24/7 LuAG flatback earrings to give you an unexpected flash of brilliance when you least expect it.

Slide to see the glow.

Sensitive Safe

Why do earrings cause irritation in the first place?
For many people, the issue is not the piercing itself — it is the metal. Many everyday earrings may contain nickel or other reactive elements, which can interact with sweat and skin over time, leading to redness, itching, or that familiar feeling of “my ears just can’t handle jewelry.”

What makes ours different?
We use ASTM F136 implant grade titanium, a medical-grade titanium alloy designed for long-term body contact. It is significantly more stable and far less reactive than many common jewelry metals, which makes it a better choice for sensitive ears and more comfortable for extended wear.

Sleep In

Why do traditional earrings feel uncomfortable when sleeping?
Most earrings are not designed for long hours of wear. Raised backs and heavier materials can press into the ear when you lie on your side, creating pressure, discomfort, or even pain against the skin and face.

How is this different?
Our flat back design sits closer and smoother against the ear, helping reduce direct pressure during rest. Combined with lightweight titanium, which creates less pull, the overall feel is more balanced and easier to wear for longer periods.

The result is simple: earrings that are comfortable enough to keep on — without needing to take them off every night before sleep.

Light & Waterproof

Why do some earrings feel heavy or change over time?
Many traditional materials like silver or gold are denser and more reactive. When exposed to water, sweat, shampoo, or chlorine — such as in swimming pools — they can gradually oxidize or darken. This is why some jewelry loses its original look and requires regular cleaning or care.

What makes titanium different?
Titanium has a much lower density than silver, which means it feels lighter and creates less pull on the ear. At the same time, it is highly chemically stable, so it does not easily react with water or everyday substances.

In practical terms, that means you can wear your earrings through daily routines — including showering or swimming — without worrying about discoloration or constant upkeep. Less maintenance, and a more effortless way to wear jewelry every day.

We Make It Easy

Why can flat back earrings feel difficult at first?
If you are not part of the piercing world, flat back earrings can seem unfamiliar. It is common to feel unsure about sizing, comfort, or how to put them on properly.

How do we make it easier?
We design our pieces with everyday wearers in mind — not just experienced piercing users. From clearer product selection to thoughtful support around fit and wear, we aim to simplify the process so you can choose and wear with confidence.

The goal is simple: make the experience feel easy from your first order to your first wear.

How to wear

Flat back earrings may feel unfamiliar at first — this guide makes it simple.

View details

01 Insert gently
Guide the flat back through the piercing slowly and steadily.

02 Secure the front piece
Carefully screw the front into place until it feels stable and aligned.

03 Adjust for comfort
Once secured, it should sit smoothly against the ear with a light, balanced feel.

Why we use an internally threaded design
You may notice that our earrings use an internally threaded closure rather than a push-pin style. While this may take a moment longer to put on at first, it is designed with long-term wear in mind.

The benefit is stability. A threaded connection stays securely in place and is less likely to loosen over time. In comparison, push-pin styles rely on tension at the connection point, which can wear down with repeated use and may become less reliable.

In simple terms, we chose this design to give you a more secure, durable, and low-maintenance experience — especially if you plan to wear your earrings daily or for extended periods of time.
