About this 0.99ct lab-grown marquise diamond

This 0.99ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG777632813 or 777632813. Listed at 3 retailers as of October 30, 2026, with prices from £598 to £791, a £193 spread on the same certified stone. The Diamond Guys lists it at £791. 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.
