This 0.53ct lab-grown marquise sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG662421614 or 662421614. Listed at 19 retailers as of October 30, 2026, with prices from £149 to £889, a £741 spread on the same certified stone. Reve Diamonds lists it at £889. 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.
