You are bidding on a 1.01 ct ROUND BRILLIANT cut loose diamond stone with F color and VS2 clarity. For someone seeking a completely colorless diamond, "F" diamonds offer the best value. This diamond will appear completely clean and white, yet is relatively less expensive than "D" and "E" color stones, which also reside in the "Colorless" category.VS diamonds (which stand for "Very Slightly Included") have inclusions that are too small to detect with the human eye. Sometimes these inclusions can be seen with a 10x "loupe" (pronounced "loop"), but in most cases a 30x microscope is needed to clearly identify the tiny clarity characteristics of this diamond. VS diamonds are the safest choice for anyone who demands a diamond totally free of visible inclusions.
