This 1.3ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG841650990 or 841650990. Listed at 5 retailers as of October 24, 2026, with prices from £373 to £1,202, a £829 spread on the same certified stone. Brilliant Earth lists it at £1,202. 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.
