This 1.38ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG790613901 or 790613901. Listed at 12 retailers as of October 23, 2026, with prices from £346 to £1,642, a £1,296 spread on the same certified stone. Do Amore Diamonds lists it at £1,642. 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.
