About this 2ct lab-grown marquise diamond

This 2ct lab-grown marquise sits in the two to three carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG844645751 or 844645751. Listed at 3 retailers as of November 1, 2026, with prices from £207 to £1,155, a £948 spread on the same certified stone. Brilliant Earth lists it at £1,155. 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.
