This 1.31ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LGG1215709 or G1215709. Listed at 2 retailers as of October 28, 2026, with prices from €411 to €964, a €553 spread on the same certified stone. MOH London lists it at €964. 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.
