This 3.07ct 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 LG847676282 or 847676282. Listed at 22 retailers as of October 27, 2026, with prices from £1,278 to £5,760, a £4,482 spread on the same certified stone. Brilliant Earth lists it at £5,760. 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.
