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 standard cut grade and certified by IGI LG591336302. 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.
