Kit 7 — Diamond Kit

The ultimate JNA Sparkle experience.

Kit 7 is our most powerful and complete kit, designed for those who demand the very best. With our largest metal polish size, a full 32 oz refill, and both an ultrasonic cleaner and a professional steam cleaner, this is the ultimate professional jewelry care setup at home.

What's included:

• 1 × 8 oz JNA Metal Polish — half of our giant 16 oz size, built to last for years. Removes tarnish, oxidation, and dullness from precious metals without harsh chemicals.
• 1 × 32 oz JNA Jewelry & Glass Cleaner — our largest size and fan-favorite refill, so you never run out.
• 1 × 8 oz JNA Jewelry & Glass Cleaner — perfect for everyday use and touch-ups.
• 1 × Ultrasonic Cleaner — uses gentle low-frequency vibrations to deep clean around diamonds and precious stones safely, without brushing that could loosen settings.
• 1 × JNA Professional Steam Cleaner — blasts away dirt and residue with the power of steam for a deep, brilliant clean. Especially amazing for watch bands like Oyster and Jubilee bracelets that collect dirt and grime between the links and traverses. Use distilled water and follow the instructions included with the steam cleaner for best and safest results.

Pro Tips:

• Fill your ultrasonic cleaner with JNA Jewelry & Glass Cleaner — enough to fully cover your items — instead of water, and let it run for about 10 minutes. Then rinse with water to fully remove any residue.
• If your metal polish starts to dry out after extended use, place the jar in the microwave with the lid on for 15 to 30 seconds to restore its consistency. Be careful — the jar may be hot when you take it out!

The diamond standard in jewelry care — for those who want it all.
