Lab grown diamonds or mined diamonds , both are real diamonds.

Each is composed of pure carbon with identical physical, chemical, and optical properties. Even professional gemologists cannot distinguish them by sight alone - only advanced instruments in a gem lab can determine their origin.

Any Difference?

Professional Certification

Every RAGAZZA lab grown diamond is carefully graded by GIA or other international institutions and comes with its own certificate, affirming its authenticity and unique identity - so you can own brilliance with confidence.
