About this 2.5ct lab-grown marquise diamond

This 2.5ct 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 LG754595348 or 754595348. Listed at 32 retailers as of October 30, 2026, with prices from £1,587 to £10,926, a £9,339 spread on the same certified stone. Do Amore Diamonds lists it at £10,926. 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.
