The GIA clarity scale is divided into 11 specific grades ranging from flawless (FL) the very best, down to heavily included (I-1, I-2, and I-3). Clarity grades ranging from VVS-1 down to SI-2 contain microscopic inclusions that require a minimum of 10X magnification to be seen. These inclusions formed in the Earth under intense heat and pressure.

GIA, AGS, EGL-USA, IGI, and HRD lab grading reports are featured on our Exceldiamonds web site.

This is the diamonds reaction to ultraviolet light. The most common color fluorescence is blue and is graded by GIA on a scale of None, Faint, Medium, and Strong. In lower color diamonds such as K, L, and M, strong fluorescence will make the stone face up whiter and thereby provides excellent value for your money. Contrary to popular reports, strong fluorescence does not negatively affect a diamonds color or transparency.
