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 VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG811664150 or 811664150. Listed at 6 retailers as of October 26, 2026, with prices from €362 to €964, a €602 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.
