About this 2.03ct lab-grown marquise diamond

This 2.03ct lab-grown marquise sits in the two to three carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818684450 or 818684450. Listed at 10 retailers as of October 30, 2026, with prices from £1,446 to £4,953, a £3,508 spread on the same certified stone. With Clarity lists it at £4,953. 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.
