What materials is the STRATUM Men’s Carbon Fibre Ring made from?

STRATUM Men’s Carbon Fibre Ring is crafted from premium tungsten carbide. Tungsten carbide is hypoallergenic and surpasses gold and titanium in hardness and scratch resistance.

Is the STRATUM Men’s Carbon Fibre Ring suitable for sensitive skin?

Yes, the STRATUM Men’s Carbon Fibre Ring is hypoallergenic and tested for purity, making it safe for sensitive skin. The tungsten carbide material contains no nickel or other common allergens.

How do I care for my STRATUM Men’s Carbon Fibre Ring?

Clean your STRATUM Men’s Carbon Fibre Ring with mild soap, warm water, and a soft cloth. Avoid abrasive pads, ultrasonic cleaners, or harsh chemicals. Always dry thoroughly before storing.

Can I wear my STRATUM Men’s Carbon Fibre Ring while swimming or showering?

We recommend removing your STRATUM Men’s Carbon Fibre Ring before swimming, showering, or prolonged water exposure. While tungsten carbide is highly durable can be affected by moisture and chemicals like chlorine.

How do I care for the wood inlay?

The natural wood inlay requires special attention to preserve its beauty. Clean gently with a soft, barely damp cloth and dry thoroughly immediately. Never expose to prolonged water, humidity, or extreme temperatures, as wood can warp, crack, or swell. Remove your ring before any water activities, hand washing, or applying lotions. Avoid harsh chemicals and abrasive cleaners. Store in a cool, dry place when not wearing.

Will the wood inlay change over time?

Yes, natural wood may develop subtle changes in color and tone with wear, creating a unique patina that reflects your ring's journey with you. This is part of the wood's organic character and individuality. With mindful care—protecting it from moisture, chemicals, and temperature extremes—the wood will age beautifully while maintaining its structural integrity and distinctive grain patterns.

Are the natural materials sustainably sourced?

Yes, sustainability is central to Foundoria's ethos. The natural wood is responsibly sourced. We work with trusted partners who share our commitment to ethical practices and environmental responsibility.

Is each STRATUM Men’s Carbon Fibre Ring unique?

Yes, because the STRATUM Men’s Carbon Fibre Ring features authentic natural wood, each ring is completely unique. The natural grain patterns, colors, and textures of the wood ensure that no two rings are ever identical, making your ring truly one-of-a-kind.
