About this 2.01ct lab-grown marquise diamond

This 2.01ct 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 LG841639355 or 841639355. Listed at 3 retailers as of November 4, 2026, with prices from £215 to £914, a £699 spread on the same certified stone. Rare Carat lists it at £914. 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.
