About this 1.22ct lab-grown heart diamond

This 1.22ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG849618831 or 849618831. Listed at 5 retailers as of October 29, 2026, with prices from £307 to £823, a £516 spread on the same certified stone. MOH London lists it at £823. 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.
