This 1.21ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG846699703 or 846699703. Listed at 11 retailers as of November 1, 2026, with prices from €230 to €1,152, a €922 spread on the same certified stone. Reve Diamonds lists it at €1,152. 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.
