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), with a very-good cut grade and certified by IGI LGG1215709. Listed at 5 retailers as of November 6, 2026, with prices from €195 to €926, a €731 spread on the same certified stone. Taylor and Hart lists it at €926. 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.
