This 1.44ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG841676786 or 841676786. Listed at 17 retailers as of October 30, 2026, with prices from £183 to £1,097, a £914 spread on the same certified stone. Brilliant Earth lists it at £1,097. 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.
