This 1.25ct 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 LG825656351 or 825656351. Listed at 17 retailers as of October 28, 2026, with prices from £170 to £1,455, a £1,285 spread on the same certified stone. Do Amore Diamonds lists it at £1,455. 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.
