Lab Grown Diamond Care: How to Clean and Protect Your Jewelry

A lab grown diamond is exactly as hard as a mined one — a perfect 10 on the Mohs scale — so the stone itself is nearly indestructible. What dulls a ring is never the diamond wearing out; it's film. Lotion, soap, skin oil and everyday grime build up on the facets and block light. The care routine below keeps the sparkle at day-one levels and protects the part that is actually delicate: the setting.

The 5-minute home cleaning routine

Do this weekly for daily-wear rings and monthly for occasional pieces. Avoid toothpaste, baking soda and abrasive cleaners — they don't harm the diamond but they scratch gold and strip rhodium plating from white gold.

When to take your ring off

About ultrasonic cleaners

Home ultrasonic machines are popular, and for a solid solitaire in perfect condition they're fine occasionally. But the vibration can loosen stones in pavé or halo settings, shake a stone with a feather inclusion, or finish the job on a prong that was already weakened. Our rule: ultrasonics are for your jeweler's bench, where someone checks the setting before and after. At home, soap and a soft brush do everything safely.

The annual check-up that saves diamonds

Prongs wear down microscopically every day — it's normal. Once a year, have a jeweler check prong tips, tighten any loose stones and give the piece a professional clean. This single habit is the difference between a ring passed down for generations and a diamond lost down a drain. PEGAFFI pieces include a complimentary annual inspection and clean — book it with your order number.
