What Are Lab-Grown Diamonds?

Lab-grown diamonds are real diamonds, just like the ones found in nature — but grown using modern technology that mimics the natural diamond formation process. They have the same physical, chemical, and optical properties as mined diamonds, and are graded by the same independent labs like IGI.

What sets them apart? They're ethical, sustainable, and a smarter choice for conscious luxury lovers. No mining. No conflict. Just pure brilliance—grown with intention.

How to Care for Your Lab Diamond Engagement Ring

To keep your lab diamond ring looking its best, treat it with the same love it symbolizes. Gently clean it using warm water, mild soap, and a soft cloth or brush. Avoid harsh chemicals, ultrasonic cleaners (if your ring includes pavé or side stones), and don’t wear it during heavy work or workouts.

We also recommend a professional cleaning and inspection once a year—because brilliance deserves maintenance too.
