Care That Matches Your Craft

Your Interlokit jewelry is made to move with you—but it deserves a little love to keep its brilliance. Sterling silver naturally develops character over time, but with the right habits, you can preserve its shine. Avoiding water, harsh chemicals, and sweat helps maintain the luster of each piece. When in doubt? Take it off and keep it safe.

Store It Like You Mean It

Humidity and clutter are your jewelry’s worst enemies. Instead of tossing pieces on the counter, use Interlokit’s reusable display cases to keep them dry, protected, and beautifully organized. Each case is airtight to slow down tarnishing and prevent scratches—because care should look as good as your jewelry.

Quick Cleans, Long-Term Shine

Gentle dish soap works wonders for regular refreshes, while silver polish or liquid dip cleaners help restore that fresh-from-the-box glow. Just rinse, dry, and you’re ready to reassemble and restyle. Patina, scratches, and signs of wear? They’re not flaws—they’re part of the story you’re telling.
