This 1.52ct lab-grown marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG731540769 or 731540769. Listed at 26 retailers as of October 27, 2026, with prices from £355 to £2,246, a £1,892 spread on the same certified stone. Brilliant Earth lists it at £2,246. 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.
