At World Minerals International, we employ a multi-stage verification process to guarantee the authenticity and quality of every diamond we supply. Our testing protocol includes:

1. Professional Thermal Conductivity Testing: Using advanced diamond testers, we verify the stone’s unique heat dispersion properties to distinguish it from simulants like cubic zirconia or moissanite.

2. UV Fluorescence Examination: We analyze each diamond’s fluorescence under ultraviolet light—a key natural characteristic that aids in authentication.

3. Microscopic Inclusions Analysis: Our gemologists examine internal features and inclusions under magnification, confirming natural formation versus synthetic alternatives.

4. Electrical Conductivity Check: Specific testing to differentiate diamonds from moissanite, which exhibits similar thermal but different electrical conductivity.

5. Certification & Documentation:Each certified diamond is accompanied by authenticated gemological reports detailing its 4Cs (Cut, Color, Clarity, Carat) and origin.
