What Excellent cut, F color and VS1 clarity mean

Cut decides how much a diamond sparkles. Excellent is the top cut grade, so light returns brightly through the top of the stone. F sits in the colorless range (D, E, F), so the stone shows no visible warmth, even in white gold or platinum. VS1 means tiny inclusions that are typically only visible under 10x magnification, not to the naked eye.

Lab grown, real diamond

A lab grown diamond is chemically, physically and optically the same as a mined diamond: real carbon crystal, the same hardness and the same fire. The difference is where it was grown, and the price.
