About this 2.54ct lab-grown marquise diamond

This 2.54ct lab-grown marquise sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG837626930 or 837626930. Listed at 9 retailers as of October 28, 2026, with prices from £1,003 to £3,164, a £2,161 spread on the same certified stone. Rare Carat lists it at £3,164. 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.
