This 0.99ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG809686126 or 809686126. Listed at 22 retailers as of October 27, 2026, with prices from £125 to £863, a £738 spread on the same certified stone. Queensmith lists it at £863. 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.
