This 1.01ct lab-grown heart sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG831690528 or 831690528. Listed at 19 retailers as of October 30, 2026, with prices from €149 to €826, a €677 spread on the same certified stone. MOH London lists it at €826. 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.
