This 0.99ct 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 LG775617113 or 775617113. Listed at 9 retailers as of October 25, 2026, with prices from £310 to £808, a £498 spread on the same certified stone. MOH London lists it at £808. 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.
