About this 0.81ct lab-grown heart diamond

This 0.81ct lab-grown heart sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG787667443 or 787667443. Listed at 3 retailers as of October 29, 2026, with prices from £228 to £1,007, a £778 spread on the same certified stone. MOH London lists it at £1,007. 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.
