About this 0.98ct lab-grown marquise diamond

This 0.98ct lab-grown marquise sits in the just-under-one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831659313 or 831659313. Listed at 5 retailers as of October 30, 2026, with prices from £148 to £622, a £475 spread on the same certified stone. Frank Darling lists it at £622. 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.
