This 3.04ct 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 LG848634173 or 848634173. Listed at 7 retailers as of October 28, 2026, with prices from £1,422 to £4,637, a £3,215 spread on the same certified stone. Rare Carat lists it at £4,637. 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.
