This 1.82ct lab-grown marquise sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG621448526 or 621448526. Listed at 18 retailers as of November 1, 2026, with prices from £300 to £1,300, a £1,000 spread on the same certified stone. MOH London lists it at £1,300. 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.
