How to Keep Your Diamonds Sparkling Over Time

Politains – Bespoke Fine Jewelry in Paris & Zurich 

Diamonds may be the hardest natural material, but they’re not immune to dullness. Over time, oil, dust, and buildup can affect their brilliance. Without proper care, even the most dazzling diamond can lose its shine. 

At Politains, we design bespoke fine jewelry in Paris and host private appointments in Zurich. Our mission: preserve the sparkle of your diamonds — for now, and forever. 

✧ Why do diamonds lose their sparkle? 

Diamonds don’t lose their quality, but external buildup can cloud them.
Lotion, makeup, perfume, limescale, and dust create a thin film that blocks light reflection — and thus dulls the sparkle. 

✧ What you need to clean your diamonds 

You don’t need any professional equipment. Just: 

• A small bowl of warm water 

• A few drops of mild soap (like Marseille soap or gentle dish soap) 

• A soft brush (baby toothbrush or soft makeup brush) 

• A clean, dry microfiber cloth 

✧ Step-by-step diamond cleaning 

1. Soak your jewelry for 10–15 minutes in soapy water. 

1. Gently brush the diamond, especially underneath the setting. 

1. Rinse with lukewarm water. 

1. Dry with a microfiber cloth, dabbing rather than rubbing. 

💡 Recommended every 2 to 4 weeks for frequently worn pieces. 

✧ What to avoid at all costs 

• Harsh chemicals (bleach, vinegar, acetone) 

• Ultrasonic machines at home, especially for pieces with delicate stones 

• Storing diamonds together, as they can scratch each other 

✧ Extra care tips 

• Store each diamond piece in a padded box or individual pouch 

• Remove your jewelry before cleaning, swimming, sports, or showering 

• Have the settings checked once a year to avoid stone loss 

✧ And for more delicate pieces? 

If your diamond ring includes softer gemstones (like emeralds or opals), avoid soaking. Prefer dry cleaning methods or consult our experts.
