6. How do I know that my Signature Diamond is Natural and NOT Lab-Grown?

There are 2 major differentiating signs.

1. The diamond grading reports clearly indicate whether the stone is a Natural diamond or Lab-grown diamond.
2. Black by Brian Gavin, Brian Gavin Signature, Blue, and other collections of natural Brian Gavin Diamonds, bear the respective Brian Gavin logo/mark on the girdle edge. In contrast, our Premium lab-grown diamonds only bear the document number and the words LAB GROWN so that the origin is unmistakable.
