Investing in lab-grown diamond jewellery is a commitment to sustainable luxury and timeless elegance. Whether it is an engagement ring, a pair of brilliant studs, or a delicate pendant, these pieces are designed to last a lifetime. However, even the hardest substance on earth requires a dedicated approach to caring for your jewellery to maintain its fire and scintillation.
Because lab-grown diamonds are chemically, physically, and optically identical to mined diamonds, they are susceptible to the same everyday “enemies”: oils from your skin, lotions, dust, and household chemicals. To ensure your treasures remain as radiant as the day you unboxed them, follow this comprehensive guide.

1. Understanding Your Lab-Grown Diamonds
Before diving into the cleaning process, it is important to understand what you are protecting. Lab-grown diamonds rate a 10 on the Mohs scale of hardness, making them incredibly durable. However, the metal settings (such as 14k gold, 18k gold, or platinum) are much softer. Properly caring for your jewellery involves protecting both the stone and the precious metal that holds it in place.
2. The Golden Rule: Regular Cleaning at Home
You don’t need expensive equipment to keep your diamonds sparkling. In fact, a major part of caring for your jewellery is the simple, regular maintenance you can do at home.
The Gentle Soak Method
For routine maintenance, follow these steps every two weeks:
- The Solution: Mix warm (not boiling) water with a few drops of mild, fragrance-free dish soap.
- The Soak: Place your jewellery in the solution for 20 to 40 minutes to soften accumulated oils.
- The Scrub: Use a brand-new, extra-soft toothbrush to gently scrub the stone, especially the pavilion (bottom part).
- The Rinse: Rinse under warm running water (ensure the drain is plugged!).
- The Dry: Pat dry with a lint-free microfibre cloth.

3. What to Avoid: Substances That Harm
When caring for your jewellery, you must be aware of substances that can damage the metal settings or create a stubborn “skin” over the gemstone.
- Chlorine and Bleach: Never wear your pieces in a swimming pool or hot tub. Chlorine can weaken gold alloys and may lead to prongs snapping off.
- Lotions and Perfumes: Apply your makeup and perfume before putting on your pieces.
- Abrasive Cleaners: Avoid toothpaste or baking soda, as these can micro-scratch the surface of gold and platinum.
4. Safe Storage Practices
How you store your pieces is a vital component of caring for your jewellery. Because diamonds can scratch other gemstones and metals, you should use:
- Individual Compartments: Use a fabric-lined box with separate sections.
- Soft Pouches: Store pieces in individual microfibre or velvet pouches.
- Avoid the “Jumble”: Never throw rings and necklaces into a single bowl.
5. Maintenance for Specific Metal Types
Effective habits for caring for your jewellery often depend on the metal it is set in:
- White Gold: May need to be “re-rhodiumed” every 1–2 years to maintain its bright white finish.
- Yellow and Rose Gold: A simple polishing cloth designed for gold can restore the shine between deep cleans.
- Platinum: While durable, it develops a “patina” over time. A professional jeweler can buff it back to a mirror-like glow if preferred.

6. Lifestyle Tips: When to Take It Off
Caring for your jewellery also involves knowing when to set it aside. “Last on, first off” is the golden mantra:
- At the Gym: Heavy lifting can warp the shape of a ring and loosen settings.
- Gardening and Cleaning: Manual labor exposes your pieces to harsh impact and abrasive dirt.
- Sleeping: Remove jewellery before bed to prevent prongs from snagging on sheets.
7. The Importance of Professional Inspections
Professional inspections are a key part of long-term caring for your jewellery. You should visit a jeweler at least once a year to:
- Check Prong Integrity: Ensure the prongs are tight to prevent the loss of a stone.
- Ultrasonic Cleaning: Remove dirt from crevices that a toothbrush cannot reach.
- Steam Cleaning: Blast away stubborn oils for a “factory-fresh” fire.
8. Travelling with Your Pieces
Don’t forget about caring for your jewellery while you are on the move. Use a dedicated travel organizer that keeps necklaces flat to prevent tangling and rings secured in padded slots. Never put valuable pieces in checked luggage.
Conclusion
Lab-grown diamonds are a marvel of modern technology. By following these mindful habits for caring for your jewellery, you can ensure your pieces remain a sparkling legacy for generations to come.
Remember: A clean diamond doesn’t just look better it performs better. Start caring for your jewellery with intention today, and it will continue to reflect light with maximum fire and brilliance for a lifetime.
