The Diamond Atelier • Care Guide

A diamond’s brilliance is its most captivating feature. However, because diamonds have a natural affinity for grease, they easily attract oils from your skin, lotions, and soaps. Over time, this creates a film that blocks light from entering the stone, causing it to look dull. To keep your Type IIa lab-grown diamond sparkling like the day you received it, a regular cleaning routine is essential.
The Expert-Approved Cleaning Method
You do not need expensive chemicals or ultrasonic machines to clean your ring. In fact, the safest method is also the simplest. We recommend cleaning your jewelry once a week using these four steps:
- Prepare a Soaking Solution: Fill a small bowl with warm (not boiling) water and add a few drops of mild, fragrance-free dish soap. Avoid moisturizing soaps, as they contain oils that will leave a residue.
- The 20-Minute Soak: Place your ring in the solution and let it soak for 20 to 30 minutes. This softens the accumulated dirt and oils trapped behind the stone or within the prongs.
- The Soft Brush Rule: Use a new, baby-soft toothbrush to gently scrub the diamond. Pay close attention to the pavilion (the underside of the stone), as this is where most dirt collects. Do not use firm bristles, as they can scratch the gold setting.
- Rinse and Pat Dry: Rinse the ring under warm running water (ensure the drain is closed!). Dry the piece with a lint-free microfiber cloth to prevent water spots.
Chemicals to Avoid
While lab-grown diamonds are incredibly durable (ranking 10 on the Mohs scale), the 14k and 18k gold they are set in can be sensitive to harsh chemicals. To protect the integrity of your setting, never use:
- Bleach or Chlorine: These can literally break down the alloys in your gold, making the setting brittle and prone to breaking. Always remove your ring before swimming in a pool.
- Abrasives: Toothpaste or baking soda may seem like good cleaners, but they are abrasive enough to dull the polish of your gold over time.
When to See a Professional
While home cleaning is great for daily maintenance, we recommend a professional inspection once a year. A jeweler can check your prongs to ensure they haven't loosened, ensuring your diamond remains securely held for decades to come.
