This 1.56ct lab-grown marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG607343674 or 607343674. Listed at 28 retailers as of October 31, 2026, with prices from £305 to £1,412, a £1,108 spread on the same certified stone. With Clarity lists it at £1,412. 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.
