About this 1.2ct lab-grown heart diamond

This 1.2ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG837622437 or 837622437. Listed at 15 retailers as of October 29, 2026, with prices from €208 to €927, a €720 spread on the same certified stone. MOH London lists it at €927. 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.
