Aurin represents the essence of modern minimalism. This men's tungsten wedding ring from Foundoria's TUNGRA Collection showcases pure tungsten carbide engineering at its finest—an 8mm black brushed band elevated by a polished rose gold inner sleeve that reveals refined sophistication with every gesture.

Where other rings rely on external decoration, Aurin's elegance is architectural. The contrast lives in the details: a sleek matte black exterior that commands attention, paired with a warm rose gold interior that only you and those closest to you will see. It's intimate luxury for the modern man who values substance over spectacle.

The Black Brushed Aesthetic

Aurin's exterior finish is a study in contemporary restraint. The black brushed tungsten carbide delivers a matte surface that absorbs light rather than reflecting it—creating a sophisticated, understated presence that works equally well in boardrooms and casual settings.

This isn't painted or coated black. The finish is integrated into the tungsten carbide itself through advanced manufacturing processes, ensuring it won't chip, flake, or wear away. The brushed texture adds subtle dimensionality, catching light with gentle variation while maintaining its modern edge.

Black tungsten offers versatility that precious metals can't match. It pairs effortlessly with any wardrobe—from formal black-tie occasions to weekend casual wear. The neutral tone complements rather than competes, making Aurin a ring that disappears into your style rather than demanding attention.

Rose Gold Interior: Hidden Elegance

The true sophistication of Aurin reveals itself when worn. While the exterior projects modern minimalism, the interior tells a different story—a polished rose gold sleeve that transforms the everyday act of glancing at your hand into a moment of personal luxury.

This isn't just decoration. The rose gold sleeve serves as a visual signature—a reminder that quality doesn't always announce itself loudly. It's the detail that catches light during a handshake, the warm gleam visible only to you, the unexpected refinement that defines genuine craftsmanship.

Rose gold's warm, slightly pink hue provides striking contrast against the cool black tungsten. This pairing creates visual depth that single-finish rings simply can't achieve. The result is a ring that feels both bold and refined, contemporary and timeless.

Why Pure Tungsten Excels

Uncompromising Durability

Aurin is crafted from premium tungsten carbide—one of the hardest materials used in jewellery, rating 9 on the Mohs hardness scale. For context, gold rates 2.5 and platinum 4. This isn't marketing hyperbole—it's materials science.

Your Aurin ring will maintain its pristine finish for decades without requiring repolishing, replating, or special maintenance. While softer metals accumulate scratches and dents that betray their age, tungsten carbide resists virtually everything daily life can throw at it. The black finish you receive is the finish you'll keep.

Substantial Presence Without Compromise

At 8mm wide, Aurin strikes the ideal balance—substantial enough to make a statement, comfortable enough for all-day wear. The band's weight gives it a premium feel that lighter materials can't replicate. This is jewellery that feels as impressive as it looks.

The comfort-fit interior ensures this substantial presence never becomes uncomfortable. We precision-engineer a gently rounded interior profile that allows the ring to slide on easily and sit naturally on your finger—no pinching, no catching, no adjustment needed throughout the day.

Hypoallergenic Assurance

Aurin is crafted from nickel-free tungsten carbide, making it completely hypoallergenic. If you've experienced reactions to other metals—particularly white gold or silver—tungsten carbide eliminates that concern entirely.

We don't just claim hypoallergenic status. Our tungsten carbide is REACH and GPSR certified, meeting the European Union's strictest product safety standards. Independent laboratory testing confirms zero nickel content and full compliance with EU chemical safety regulations. This legal certification ensures Aurin is safe for even the most sensitive skin.

The TUNGRA Promise

Every ring in the TUNGRA collection celebrates pure tungsten engineering without compromise. No inlays mean no special maintenance, no water restrictions, no material limitations. Just exceptional hardness, enduring beauty, and modern design that speaks for itself.

Aurin is built to match your commitment—a ring engineered to last a lifetime and designed for the man who appreciates quality that doesn't need explanation.

Tungsten Carbide: Engineering Excellence

Tungsten carbide forms when tungsten—the element with the highest melting point of any pure metal at 3,422°C—is bonded with carbon under extreme pressure and temperature. The resulting compound rates 9 on the Mohs hardness scale, surpassed only by diamond and cubic zirconia.

This exceptional hardness translates directly to real-world performance. Your Aurin ring will resist scratches from virtually everything in daily life—keys, tools, desk surfaces, weights, door frames. While precious metals require periodic repolishing to remove accumulated scratches, tungsten carbide's finish is permanent.

The black finish isn't a coating that can wear away. It's created through advanced manufacturing processes that integrate the color into the tungsten carbide structure itself. This means the black you see today is the black you'll see decades from now—no fading, no chipping, no wearing through to reveal base metal underneath.

REACH & GPSR Certification

Aurin carries REACH and GPSR certification—the European Union's most rigorous product safety standards. This isn't optional labelling or self-certification. It's mandatory third-party testing that verifies every chemical component meets strict safety thresholds.

REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) requires manufacturers to prove that products contain no hazardous substances above legal limits. GPSR (General Product Safety Regulation) mandates that products sold in the EU meet baseline safety requirements before they can legally enter the market.

For Aurin, this means independent laboratories have tested and verified zero nickel content, confirmed the safety of all materials in direct skin contact, and validated that the ring meets EU standards for consumer safety. You're not trusting our word—you're trusting certified, legally-binding laboratory results.

Rose Gold Accent: Warm Sophistication

The rose gold interior sleeve isn't just decorative—it's precision-engineered to fit seamlessly within the tungsten structure. Rose gold, an alloy of gold, copper, and sometimes silver, brings warmth and subtle luxury to Aurin's modern design.

The polished finish of the rose gold sleeve creates deliberate contrast with the matte black exterior. This dual-finish approach adds visual complexity without overwhelming the minimalist aesthetic. The result is a ring that reveals more character the longer you wear it.

Comfort-Fit Engineering

The comfort-fit interior is precision-machined to create a gently rounded profile that sits naturally on your finger. Traditional flat-interior rings can pinch or catch on skin, especially during temperature changes or physical activity. Comfort-fit eliminates these issues entirely.

The rounded interior allows Aurin to slide on easily despite tungsten's substantial weight. Once worn, the ring distributes pressure evenly around your finger rather than creating pressure points. This engineering detail transforms a heavy material into comfortable all-day wear.

Manufacturing Standards

Every Foundoria ring is manufactured to surgical-grade precision standards. We use Computer Numerical Control (CNC) machining for tolerances measured in microns, ensuring perfect symmetry, consistent dimensions, and flawless finish quality.

Quality control inspections verify dimensions, finish quality, structural integrity, and safety compliance before any ring enters our inventory. This systematic approach ensures the Aurin you receive meets the same exacting standards as every other ring we produce.

Aurin requires minimal maintenance. Pure tungsten carbide with no natural inlays means no special care restrictions, no water sensitivity, no material limitations. This is a ring engineered for genuine daily wear.

Understanding Tungsten's Properties

Tungsten carbide is exceptionally hard but not unbreakable. While it resists scratches better than any other jewellery material, it can crack under extreme impact—dropping from height onto concrete, striking against stone surfaces, or compression in heavy machinery.

For normal daily wear, this isn't a concern. Tungsten carbide handles everything from desk work to gym sessions without issue. The impact required to damage tungsten exceeds what you'll encounter in typical daily activities.

What to Avoid

Never use: Harsh abrasive cleaners, wire brushes, ultrasonic cleaners designed for softer metals, or harsh chemicals (bleach, chlorine in high concentrations). While Aurin is more chemical-resistant than precious metals, avoid unnecessary exposure to extreme chemicals.

Store Aurin in the provided presentation box when not worn to prevent accidental impacts with other jewellery or hard objects. While tungsten won't scratch easily, it can scratch softer metals if stored together.

When to Use Your ENDURA Ring

Your complimentary ENDURA silicone ring is perfect for activities where impact risk is higher—heavy manual labor, contact sports, rock climbing, or situations where you'd prefer not to wear your tungsten ring. The silicone ring keeps your finger comfortable and protected while keeping Aurin safe.

With basic care, your Aurin ring will maintain its pristine appearance for decades. The black finish won't fade, the rose gold won't tarnish, and the tungsten won't bend or lose its shape. This is engineering built to last.
