About this 0.9ct lab-grown marquise diamond

This 0.9ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836614544 or 836614544. Listed at 15 retailers as of November 4, 2026, with prices from £187 to £966, a £779 spread on the same certified stone. Brilliant Earth lists it at £966. 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.
