Cosmos - Tungsten Ring with Galaxy Foil

Cosmos brings the universe within reach. This men's tungsten wedding ring from Foundoria's CELESTIUM Collection captures nebulae and distant galaxies in wearable form—galaxy foil shimmering with blues, purples, and iridescent highlights, all framed by hammered black tungsten carbide that reflects light like starlight on ancient stone.

Every facet of Cosmos tells a celestial story. The hammered texture creates countless light-catching surfaces that shift and sparkle with movement, while the galaxy foil inlay glows with ethereal colours that seem to shift depending on angle and illumination. This isn't printed imagery—it's genuine metallic foil with optical properties that create genuine depth and dimension.

The Hammered Black Aesthetic

Cosmos's 8mm tungsten carbide band features a hammered, faceted finish—a textured surface created through precision manufacturing that mimics the organic beauty of hand-forged metal. Each facet catches and reflects light independently, creating dynamic visual interest that changes with every gesture.

This texture serves both aesthetic and practical purposes. The faceted surface diffuses light rather than creating harsh reflections, giving the black tungsten a sophisticated, almost organic quality. The varied surface angles also help hide minor contact marks that might show on polished surfaces, ensuring Cosmos maintains its pristine appearance through daily wear.

The hammered finish isn't applied—it's created during manufacturing through specialized processes that shape the tungsten carbide itself. This means the texture is permanent, integrated into the material rather than sitting on top of it. The finish you see today is the finish you'll see decades from now.

Galaxy Foil: Captured Nebulae

The centerpiece of Cosmos is its galaxy foil inlay—a specialized metallic material that displays dichroic properties, shifting between blues, purples, and iridescent highlights depending on viewing angle and light conditions. This optical effect creates the illusion of depth, as though you're gazing into distant space.

Galaxy foil achieves its colour-shifting properties through multiple ultra-thin metallic layers that interfere with light waves. Different wavelengths reflect at different angles, creating the characteristic shimmer and colour shift. The effect is mesmerizing—tilting your hand reveals new colours and patterns, much like nebulae photographed through different filters.

No two pieces of galaxy foil are identical. The way colours shift, the intensity of iridescence, and the pattern of highlights vary based on the foil's orientation and the viewer's perspective. Your Cosmos ring displays a genuinely unique cosmic palette—personal galaxies that belong to you alone.

The 8mm Flat Profile

At 8mm wide, Cosmos delivers substantial presence without overwhelming proportion. The flat profile creates clean, modern lines that appeal to contemporary tastes while providing ample canvas for both the hammered texture and galaxy foil to showcase their beauty.

This width strikes the ideal balance for men who want a ring that makes a statement without excessive size. Substantial enough to display the complex textures and colours, comfortable enough for all-day wear, and proportioned to suit a range of finger sizes and hand types.

Engineering That Transcends

Tungsten Carbide Foundation

Cosmos is built upon premium tungsten carbide—rating 9 on the Mohs hardness scale. This exceptional hardness means your ring will maintain its hammered texture and pristine appearance for decades without requiring repolishing or special maintenance.

While softer metals like gold (2.5 Mohs) and platinum (4 Mohs) lose definition in textured finishes as they wear, tungsten carbide's hardness preserves every facet permanently. The hammered texture you receive is the texture you'll keep—each facet maintaining its crisp edges and light-catching properties indefinitely.

Hypoallergenic Assurance

Cosmos uses nickel-free tungsten carbide, making it completely hypoallergenic. If you've experienced reactions to other jewelry metals, tungsten carbide eliminates that concern entirely.

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 Cosmos is safe for even the most sensitive skin.

Comfort-Fit Interior

The comfort-fit interior is precision-engineered with a gently rounded profile that contrasts beautifully with the textured exterior. While the outside displays complex faceted surfaces, the inside offers smooth, rounded comfort that allows the ring to slide on easily and sit naturally on your finger.

This dual-surface approach—textured exterior, smooth interior—demonstrates thoughtful engineering. The exterior provides visual and tactile interest while the interior ensures all-day comfort. Despite tungsten's substantial weight, this ergonomic design ensures comfortable wear without adjustment.

Built for the Journey

Cosmos is engineered for genuine daily wear. The galaxy foil inlay is sealed with our proprietary protection system—a multi-layer process that makes it water-resistant and durable while preserving its colour-shifting optical properties.

Combined with tungsten's legendary scratch resistance and the permanent hammered finish, Cosmos requires only basic care to maintain its cosmic beauty for decades. This is jewelry built to match your commitment—designed to last, engineered to endure, crafted to inspire wonder every time you glance at your hand.

Tungsten Carbide: Permanent Precision

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 is particularly important for textured finishes like Cosmos's hammered surface. Softer metals lose definition in their textures as they wear—facets become rounded, edges become soft, detail disappears. Tungsten carbide preserves every facet with absolute fidelity.

The hammered finish is created during manufacturing through specialized tooling that shapes the tungsten carbide into countless small facets. Because the texture is formed in the material itself rather than applied as a coating, it's permanent. Each facet maintains its crisp edges and light-catching angles indefinitely.

Galaxy Foil: Optical Engineering

Galaxy foil achieves its distinctive appearance through dichroic properties—optical effects created by multiple ultra-thin metallic layers. When light hits these layers, different wavelengths reflect at different angles, creating the characteristic colour shift and iridescent shimmer.

This isn't paint or dye that simply absorbs certain wavelengths. It's structural colour created through light interference—the same optical principle that creates rainbow patterns in oil slicks or the iridescence in butterfly wings. The colours you see are created by the physical structure of the material interacting with light.

The foil displays blues, purples, and iridescent highlights that shift as you move your hand. Viewing angle, light source, and even the colour of surrounding surfaces affect how the foil appears at any given moment. This dynamic quality ensures Cosmos never looks exactly the same twice—a constantly evolving cosmic display.

Each piece of galaxy foil is unique. The intensity of colour shift, the specific hues visible from different angles, and the pattern of iridescence vary based on the foil's composition and orientation. Your Cosmos ring contains a genuinely one-of-a-kind arrangement of optical effects.

REACH & GPSR Certification

Cosmos carries REACH and GPSR certification—the European Union's most rigorous product safety standards. This isn't voluntary labeling or self-assessment. It's mandatory third-party testing that verifies every material component meets strict safety thresholds before the product can legally enter the EU market.

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 meet baseline safety requirements for consumer use.

For Cosmos, 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 trusting certified, legally-binding laboratory results, not manufacturer promises.

Sealed Protection System

The galaxy foil inlay is protected with our proprietary sealing system—a multi-layer process that makes the material water-resistant and durable for daily wear while preserving its optical properties.

This sealing process is critical for foil materials. Without proper protection, foil can degrade when exposed to moisture, oils, or chemicals. Our sealing system creates a barrier that protects the foil while maintaining optical clarity—ensuring the colour-shifting effects remain vibrant for decades.

Comfort-Fit Engineering

The comfort-fit interior is precision-machined using Computer Numerical Control (CNC) technology for tolerances measured in microns. This creates a gently rounded profile that allows the ring to slide on easily despite tungsten's substantial weight.

The contrast between exterior and interior is deliberate engineering. The hammered exterior provides visual and tactile interest—you can feel the faceted texture when you touch the ring. The smooth interior ensures that texture never causes discomfort when worn, distributing pressure evenly around your finger.

Manufacturing Standards

Every Foundoria ring is manufactured to surgical-grade precision standards. Quality control inspections verify dimensions, texture consistency, inlay integrity, and safety compliance before any ring enters our inventory.

For textured finishes like Cosmos's hammered surface, quality control includes specific checks to ensure consistent facet size, proper light reflection characteristics, and uniform texture distribution. This systematic approach ensures the Cosmos you receive meets identical standards to every other ring we produce.

Cosmos is engineered for daily wear, but the galaxy foil inlay requires mindful care to maintain its colour-shifting brilliance for a lifetime.

Galaxy Foil Care Essentials

The galaxy foil inlay is sealed and protected, but the material's optical properties can be affected by moisture. Brief exposure during handwashing is fine—the seal protects against splashes. However, prolonged water exposure (showers, swimming, dishwashing) should be avoided.

If your ring gets wet, dry it immediately with a soft cloth. Don't leave it damp. The foil is sealed, but extended moisture exposure serves no purpose and risks compromising the seal over time.

Never use: Harsh chemicals (bleach, chlorine), abrasive cleaners, ultrasonic cleaners, steam cleaners, or soaking water. These can damage the seal or affect the foil's optical properties.

Caring for the Hammered Texture

The hammered, faceted finish is low-maintenance due to tungsten's exceptional hardness. The texture helps diffuse minor contact marks that might show on polished surfaces, meaning Cosmos maintains its appearance with minimal intervention.

When cleaning, use a soft cloth and follow the texture—wiping along the facets rather than against them. This ensures you're cleaning effectively while respecting the surface geometry.

Understanding Tungsten's Properties

While tungsten carbide resists scratches better than any other jewelry 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.

Storage Guidance

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

Keep the ring away from extreme temperatures and direct sunlight for extended periods. While the materials are stable, unnecessary exposure to extremes serves no purpose and could potentially affect the foil's appearance over very long timeframes.

With proper care, your Cosmos ring will maintain its colour-shifting brilliance and hammered texture for decades. The foil will continue displaying its cosmic palette, the texture won't soften, and the tungsten won't bend or lose its shape.
