About this 1.09ct lab-grown heart diamond

This 1.09ct 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 LG808638928 or 808638928. Listed at 21 retailers as of October 26, 2026, with prices from €205 to €972, a €766 spread on the same certified stone. Brilliant Earth lists it at €972. 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.
