About this 1.14ct lab-grown marquise diamond

This 1.14ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG546298663 or 546298663. Listed at 14 retailers as of October 29, 2026, with prices from €171 to €996, a €825 spread on the same certified stone. MOH London lists it at €996. 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.
