This 3ct lab-grown marquise sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG835602889 or 835602889. Listed at 4 retailers as of October 31, 2026, with prices from £1,337 to £4,865, a £3,528 spread on the same certified stone. Taylor and Hart lists it at £4,865. 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.
