This 1.28ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG847616073 or 847616073. Listed at 9 retailers as of October 29, 2026, with prices from £146 to £853, a £707 spread on the same certified stone. MOH London lists it at £853. 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.
