About this 2ct lab-grown marquise diamond

This 2ct lab-grown marquise sits in the two to three carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG846656721 or 846656721. Listed at 13 retailers as of November 1, 2026, with prices from £277 to £1,155, a £878 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.
