At Justyna Grace, we believe jewelry should be a seamless part of your life—beautiful enough for a gala, yet durable enough for a morning workout. To achieve this, we use two premium grades of stainless steel, each chosen for a specific purpose. Here is everything you need to know about the "silent heroes" behind your favorite pieces.

1. The Gold Standard: 316L Surgical Grade Steel

When you see 316L on our site, you’re looking at our "Performance" collection. This is the same grade of steel used in high-end Swiss watches and medical implants.

Why It’s a Must-Have:

• Life-Proof Durability: 316L contains molybdenum, an element that makes it virtually immune to "pitting" or rusting. Whether you’re at the beach, in the pool, or at the gym, these pieces stay flawless.

• Hypoallergenic Comfort: This grade is specifically designed to lock in nickel, making it the safest choice for those with sensitive skin or new piercings.

• The Perfect Partner for PVD: Our 18K gold PVD coating bonds best with 316L, creating a "tarnish-free" finish that lasts years, not months.

Best for: Rings, everyday earrings, and "forever" necklaces you never want to take off.

2. The Artisan Choice: 304 Stainless Steel

Not all jewelry is meant for the gym; some is meant to make a statement. That is where 304 Stainless Steel shines. Known for its incredible luster and strength, 304 is the industry standard for luxury home accents and architectural design.

Why We Love It:

• Intricate Artistry: 304 is slightly more malleable, allowing our designers to craft complex textures and bold, sculptural shapes that harder metals can’t achieve.

• Lightweight Luxury: It is the ideal choice for oversized hoops or chunky layered chains. You get that heavy, high-fashion look without the weight, ensuring you stay comfortable all day.

• Mirror-Like Shine: 304 takes an exceptional polish, giving our silver-toned pieces a high-shine radiance that rivals white gold or platinum.

Best for: Statement necklaces, bold hoops, and intricate fashion charms.

The Finishing Touch: PVD Gold Coating

To give our jewelry its signature 18K glow, we move beyond traditional plating. We use PVD (Physical Vapor Deposition)—a vacuum-sealing process that fuses gold to the steel at a molecular level.

• 10x More Durable than standard gold plating.

• Eco-Friendly "dry" process with no chemical runoff.

• Sweat & Water Resistant for a worry-free lifestyle.
