This 0.78ct lab-grown marquise sits in the just-under-one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG816645995 or 816645995. Listed at 17 retailers as of November 1, 2026, with prices from $146 to $846, a $700 spread on the same certified stone. MOH London lists it at $846. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
