Performance Jewelry (n.)

Jewelry designed to be worn continuously through movement, sweat, travel, and daily life—without removal, discomfort, or damage.

Performance jewelry is designed to move with the body—offering flexibility, durability, and comfort during daily activity, travel, or exercise.

Historically, the term has been associated with stage jewelry (rhinestones, competition wear) or novelty tech accessories. Today, KADEN & KAI is taking a new approach that is redefining the category.

Absolutely. They are designed for movement — perfect for running, yoga, tennis, weight lifting, and everyday activity.

Yes. The earring components that touch your ears — the hooks and posts — are made from hypoallergenic, surgical steel, which is commonly used in jewelry designed for sensitive ears. You also have the option to select Titanium earring hooks if you have extreme sensitivity.

The sculptural earring elements themselves are crafted from Verdasil®, an FDA-grade silicone that is naturally gentle on skin.

Although our hooks and posts are made from hypoallergenic, surgical steel, which is commonly used in jewelry designed for sensitive ears, some people have extreme metal sensitivity so we offer F135 Implant Grade Titanium Hooks. F136 Implant Grade is a specific titanium classification that's medical-grade and safe for long-term body contact. Here's what it means:

• F136 – This is the ASTM standard designation for implant-grade titanium, the highest purity level. It's the same material used in surgical implants and body piercings.
• Hypoallergenic – It contains no nickel, lead, or harmful metals that trigger allergic reactions. It won't cause itching, redness, or irritation even on ultra-sensitive skin.

Why it matters for earrings:

• Safe for sensitive ears and nickel allergies
• Non-toxic and biocompatible with your skin
• Won't discolor, fade, or turn green over time
• Lightweight and durable for all-day wear

KADEN & KAI® jewelry is made from Verdasil® — our proprietary performance silicone — which does not absorb moisture and will not tarnish or corrode when exposed to sweat. Unlike many traditional metals or plated jewelry, Verdasil® maintains its color, flexibility, and finish even during workouts or hot weather.

Because it doesn’t tarnish, rust, or absorb oils, KADEN & KAI jewelry maintains a clean, sculptural look even during workouts, travel, or hot summer days.

KADEN & KAI® creates sustainable jewelry built on three pillars: Material Sustainability, Ethical & Production Sustainability, and Style Sustainability. These principles guide how every piece is designed, produced, and worn.

Material Sustainability

Our jewelry is crafted from Verdasil® performance silicone, a material designed to reduce environmental impact. Verdasil® is FDA-grade, hypoallergenic, vegan-friendly, and recyclable, and engineered to remain stable over time without degrading, releasing toxins, or shedding microplastics.

Ethical & Production Sustainability

We apply responsible practices throughout our business, including small-batch production, fair labor practices, local manufacturing, and low-waste processes. Each piece is thoughtfully constructed for durability so it can be worn and enjoyed for years.

Style Sustainability

We believe sustainable jewelry should be worn often and loved for a long time. Our designs are intentionally versatile, timeless, and durable, encouraging long-term wear rather than fast fashion cycles.

Together, these three pillars define the foundation of KADEN & KAI® sustainable jewelry.
