This 1.42ct 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 LG852642865 or 852642865. Listed at 7 retailers as of November 1, 2026, with prices from €299 to €1,032, a €733 spread on the same certified stone. MOH London lists it at €1,032. 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.
