The report certificates grade the diamond. For natural diamonds, the GIA certificate report is the gold standard. For lab grown diamonds, we recommend IGI.
Report
GIA IGI GCALFluorescence refers to whether or not a stone will produce a color reaction when exposed to long-wave ultraviolet (UV) light (such as the light that comes from black light). None and faint is considered more desirable for diamonds graded D through G, and medium and strong can make diamonds H color and lower look whiter.

The symmetry of a diamond refers to the shape, placement and alignment of the facets. With poor symmetry the facets may have external imbalances that can misdirect light as it travels within the stone. Look for "Very good" and "Excellent" symmetry.
